NetWorker Components
Several components make up the NetWorker environment and provide the ability to
protect against data loss.
The following figure illustrates the main components in a NetWorker environment.
Figure 1 NetWorker components
NMC Server
The NetWorker Management Console (NMC) server or Console server is a Java-based
application and database server. The NMC Server manages all NetWorker Servers and
Clients. The NMC Server provides reporting and monitoring capabilities for all
NetWorker Servers and Clients in the environment. The NMC Server relies on the
NetWorker Authentication Service for user account authentication.
Datazone
A NetWorker datazone is composed of a single NetWorker Server, its clients, and
storage nodes. You can add additional datazones as backup requirements increase.
NetWorker Server
The NetWorker Server is a collection of processes and programs that are installed on
a host that performs NetWorker services. The NetWorker Server also acts as a
storage node and can control multiple remote storage nodes.
NetWorker client
A NetWorker client is a physical or virtual computer on which you install the
NetWorker client software on. The NetWorker client computer can be any computer
in a datazone that contains data you want to back up. The NMC server, NetWorker
server, and NetWorker storage node hosts are also NetWorker clients.
to use NetWorker REST API, and the NetWorker REST API Reference Guide provides a
full description of the API resources.
Restricted datazones
Restricted datazones provide NetWorker administrators with the ability to organize a
NetWorker environment into a multi-tenancy configuration.
In a multi-tenancy configuration, each restricted datazone contains one NetWorker
server and other associated NetWorker resources. Global administrators oversee the
setup and management of several restricted data zones and assign tenant
administrators with access to a restricted datazone. A tenant administrator can only
manage NetWorker resources within an assigned restricted datazone.
Virtual environments
The NetWorker Vmware Integration Guide provides more information on the virtual
environment solutions from Networker.
NetWorker services
The main services and programs for the NetWorker Server are the NetWorker Storage
Node, NetWorker Client, and the NetWorker Management Console (NMC) server.
This section includes information on the NetWorker services, and how to start and
stop the services.

floating windows that can be viewed simultaneously. The following table describes the
various types of information available in the docking panel, and the details each one
provides.
Sessions Allows you to customize whether to display all session types, or only
certain session types. The information that is provided depends on
which session type you select. For example, if you select Save
Sessions, the window lists clients, save sets, groups, backup level,
backup start time, duration of the backup, devices, rate, and size.
Sessions window on page 57 provides more information.
Alerts Lists the priority, category, time, and message of any alerts. Alerts
pane on page 58 provides more information.
Devices Lists devices, device status, storage nodes, libraries, volumes, pools,
and related messages. Devices pane on page 59 provides more
information.
Operations Lists the status of all library and silo operations, including nsrjb
operations that are run from the command prompt. Also lists user
input, libraries, origin, operation data, operation start time, duration of
the operation, progress messages, and error messages.
Log Lists messages that are generated by the NetWorker server, including
the priority of each message, the time the message was generated,
the source of the message, and the category. Log window on page
62 provides more information.
Sessions window
Use the Sessions window to view the sessions that are running on a NetWorker
server. You can change the view of this window to display these sessions:
The Sessions pane below the Policies/Actions pane provides details on individual
save, recover, clone, and synthetic full sessions by client.
To view all sessions or to limit the list of sessions by the session type, click the tabs at
the bottom of the Sessions pane. Session types include:
l Save
l Recover
l Clone
l Browse
l Synthetic Full/Rehydrated Sessions
l All
To change the displayed session types go to View > Show, and select the type of
sessions to display. To display all sessions currently running on the NetWorker Server,
regardless of type, select All Sessions.
You can stop a session (backup, synthetic full backup, clone, and recovery sessions)
from the Monitoring window, even if the session was started by running the
nsrworkflow command.
To stop a session, right-click the workflow in the pane, and select Stop from the list
box.
Alerts pane
The Alerts pane displays alerts that are generated by a particular NetWorker server or
Data Domain system that has devices that are configured on the NetWorker server.
The Alerts pane includes priority, category, time, and message information.
An icon represents the priority of the alert. The following table lists and describes
each icon.
When items on the Alerts pane are sorted by the Priority column, they are sorted in
alphabetical order based on the label of the icon.
Removing alerts
Remove individual alert messages from the Events tables by removing them from the
Events table. To delete a message in the Events table, right-click the message, and
select Dismiss.
About this task
Note: The alert message remains in the Log window in the NetWorker
Administration program.
Devices pane
The Devices pane allows you to monitor the status of all devices, including NDMP
devices. If the NetWorker server uses shared and logical devices, the window is
adjusted dynamically to present a set of columns appropriate for the current
configuration.
The Devices pane provides the following information:
l Status of the operation.
l Name of the device.
l Name of the storage node that contains the device.
l For tape devices, the name of the library that contains the device.
l Name of the volume in the device.
l Name of the pool that is associated with the volume.
l Last message generated for the device.
l Whether the operation requires user input.
For example, a labeling operation may want the user to acknowledge whether the
system should overwrite the label on a tape.
Entering user input on page 61 provides instructions on how to deal with a user
input notification.
If the current server configuration includes a shared device, a Shared Device Name
column appears on the Devices pane. The name of the shared device appears in the
Shared Device Name column. If other devices for that configuration are not shared
devices, then the Shared Device Name column is blank for those devices. Only a
single device per hardware ID can be active at any particular moment. The information
for inactive shared devices is filtered out, and as a result, only one device per
hardware ID is presented on the window at any time.
An icon represents the device status. The following table lists and describes each icon.
When you sort items in the Devices pane by the Status column, NetWorker sorts the
devices in alphabetical order based on the label name of the icon.
Operations window
The Operations window displays information about device operations. It provides the
following information:
l Status of the operation.
l Name of the library.
l Whether the operation requires user input.
For example, a labeling operation may want the user to acknowledge whether the
system should overwrite the label on a tape. Entering user input on page 61
provides instructions on how to deal with a user input notification.
l The origin, or source, of the operation.
For example, the interface, nsrjb or the NetWorker server.
l Time the operation started.
l Type of operation.
l Duration of the operation.
l Status messages from the operation.
l Any error messages.
NOTICE Only the last error message of the operation appears in the Error
Messages column. Move the mouse pointer over the cell containing the last
error message to display the entire list of error messages.
The operation status is represented by an icon. The following table lists and describes
each of the icons.
When items on the Operations window are sorted by the Status column, they are
sorted in alphabetical order based on the label of the icon.

Scheduling backups
Perform scheduled backups to automatically backup client data on an ongoing basis.
Data protection policies enable you to define the client resources, schedule, and other
settings for the backup. The client resources and backup storage resources must also
be configured.
Procedure
1. Configure the backup storage resources:
a. Configure the storage node that will own the backup storage devices.
b. Configure the backup storage device.
c. Create a label template for labeling volumes, or use one of the preconfigured
label templates.
d. Create media pools for sorting and storing backup data.
Backup Target on page 75 provides more information on configuring backup
storage resources.
2. Configure one or more client resources for each client computer by using either
the Client Backup Configuration Wizard or the Client Properties dialog box.
When you configure a client resource, you specify backup settings for the
client, including:
l The save sets for the client, which define the data to back up on the client.
l Whether to automatically restart failed backups from a known good point,
which is called checkpoint restart.
l Whether to bypass the storage node and send backup data directly to AFTD
or DD Boost storage devices, which is called Client Direct.
l Directives that control how the NetWorker server processes files and
directories during the backup.
l Probe resources for probe-based backups, where the NetWorker server
probes the client for a user-defined script before the backup starts.
l Whether to back up each save set for the client by using multiple parallel
save streams.
l Backup command customizations.
Client resources on page 475 provides more information on configuring client
resources.
b. Create a policy.
Policies provide a container for the workflows, actions, and groups that
support and define the backup.
where:
l -s NetWorker_server—Specifies the name of the NetWorker Server. Use
this option when you use the nsrlogin command on a NetWorker host that
is not the NetWorker Server.
l -H authentication_host—Specifies the name of the NetWorker
Authentication Service host. Use this option when you use the nsrlogin
command on a NetWorker host that is not the NetWorker Server. This
option is only required when you do not use the -s option.
l -P port—Specifies the NetWorker Authentication Service port number.
Use this option when you do not use the -s option and when the NetWorker
Authentication Service does not use the default port number 9090 for
communications.
l -t tenant— Specifies the tenant name that the NetWorker Authentication
Service should use to verify the username and password. When you omit this
option, NetWorker Authentication Service uses the Default tenant to verify
the user credentials.
l -d logindomain—Specifies the domain name that the NetWorker
Authentication Service should use to verify the username and password with
an external authentication authority. When you omit this option, the
NetWorker Authentication Service uses the local user database to verify the
user credentials.
l -u username—Specifies the username that the NetWorker Authentication
Service should validate to generate a token.
l -p "password"—Specifies the password that the NetWorker
Authentication Service should use to verify the username. If you do not
specify the password, the nsrlogin command prompts you to provide the
password.
For example, to generate a token for user Konstantin in the idddomain domain
and the idd tenant, type the following command:
Authentication succeeded.
account that does not have the required privilege, a message similar to the
following appears:
Permission denied, user must have the 'Operate NetWorker'
privilege'.
Results
The CLI command uses the authenticated token, until the token expires. By default
the token expiration period is 480 minutes or 8 hours. When the token expires and the
user tries to run a CLI command, the command fails with a permissions error and a
message similar to the following appears to indicate that the token has expired:
Security token has expired
To resolve this issue, run the nsrlogin command again to generate a new
authenticated token.
Note: To revoke the user token and enable the CLI commands to use the Users
attribute in the Usergroups resources to authenticate users, use the nsrlogout
command. The nsrlogout UNIX man page and the NetWorker Command
Reference Guide provides detailed information about the nsrlogout command.
l Review the NetWorker daemon.raw log file on both the NetWorker server
and client hosts. Use the nsr_render_log program to review the log file in a
readable format. The NetWorker Command Reference Guide describes how to
use the nsr_render_log program.
The location of the daemon.raw file is different on Windows and UNIX:
n On Windows, the log file appears in the C:\Program Files\EMC
NetWorker\nsr\logs directory.
n On UNIX, the log file appears in the /nsr/logs directory.
l To determine the cause, refer to the Troubleshooting chapter.
l Review the operating system log files (Application event log on a Windows
client) for more information.
The UNIX man pages describe how to use the save program.

Label templates
The NetWorker server creates a unique label for each volume by applying a label
template. This section describes how label templates and media pools are used to sort,
store, and track data on media volumes.
2. Labels the volume with the name specified in the Volume Name attribute by using
one of the following:
l The next sequential label from the label template that is associated with the
chosen pool.
If a recyclable volume from the same pool is relabeled, the volume label name
and sequence number remain the same, but access to the original data on the
volume is destroyed. The volume becomes available for new data.
l An override volume name that was entered by the user.
Attribute Guidelines
Name Keep the label name consistent with the media pool name, so that the label
name reflects how the data is organized. For example, a label template
Attribute Guidelines
named "AcctFull" would identify volumes that belong to a media pool called
"Accounting Full."
/\*?[]()$!^;’"’~<>&|{}:-._
Fields A label template is made up of one or more fields. Each field, or component,
provides a layer of specificity to your organizational structure. There can
be any number of components, but it is best to keep the template simple
with as few as necessary. The label cannot exceed 64 characters.
Each range includes a start value, a dash (-), and an end value. The
start value and the end value must have the same number of
characters. For example, use 01-99 (not 1-99) or aaa-zzz (not aa-zzz).
The order in which you enter each component of the Field attribute is
important.
The NetWorker Server applies each component in a left-to-right order,
starting with the first one entered.
Separator Choose the symbol to appear between component entries. Use the period,
dash, colon, or underscore to separate each component of the label
template. If label components do not have separators (for example,
AA00aa), the labels can be difficult to read.
Next Choose the next sequence number to write on the label that the
NetWorker Server places on a volume (according to the template).
l To force a label to start the label scheme at a particular point, type a
start label value. The server continues to generate labels from that
point on, according to the rules of the template.
l To have the NetWorker Server generate the first label, leave this
attribute blank.
The following table lists examples of number sequences for volume labels.
az.00...az.99,
ba.00,...ba.99
zz.00,...zz.99
The label template should allow for expansion of the backup media storage system.
For example, it is better to create a template for 100 tapes and not use all of them,
than it is to create a template for only 10 tapes and run out of labels. When the server
reaches the end of the template numbering sequence, it wraps to the starting value.
For example, after zz.99 (used for the 67,600th label), the next label the server uses
is aa.00 for label 67,601.
Note: When the NetWorker server recycles a volume, the volume label does not
change if the volume remains in the same media pool. That is, if a volume labeled
Dev.006 is recycled, it will retain the volume label Dev.006 and will not receive a
new label with the next sequence number. The original data on the volume,
however, will be overwritten by the new data.
jupiter.001
Consider that the simpler a convention is, the easier it can be understood by operators
and administrators.
The maximum length for a volume name is 63 characters. With advanced file type
devices (adv_file), the maximum length is 60 characters.
Each volume should have a physical (adhesive) label attached to it. Since the
NetWorker server keeps track of the backups and which volumes they are on, you can
name the volumes with any convenient name. For example, you can label your volumes
1, 2, 3, or Monday.1, Tuesday.1, Wednesday.1. You can assign a volume any name as
long as each one is unique.
The adhesive label on the volume should match the name generated by NetWorker.
For example, if you physically label a volume mars.1, its NetWorker name should also
be mars.1.
Media pools
NetWorker uses media pools and volume labels to sort backup and clone data on
media.
Media is a specific collection of volumes to which the NetWorker server writes data.
For example, a tape volume or a Data Domain device. A volume is identified with a
unique label based on user configurable label templates.
Media pools act as filters that tell the NetWorker server which backup volumes should
receive specific data. The NetWorker server uses media pools along with label
templates to track what data is on which specific volume. When you use a barcode-
enabled tape library, the NetWorker server uses media pools along with the volume
barcode Labels to track which data is on a specific volume.
Note: NetWorker does not use media pools for backup and clone operations to
deduplication devices.
Data Domain Default Clone Receives clone data to DD Boost devices only.
NetWorker Data Domain Boost Integration Guide
provides more information about how to use
NetWorker with DD Boost devices.
DD Cloud Tier Default Clone Receives clone data on DD Cloud Tier devices
only. NetWorker Data Domain Boost Integration
Guide provides more information about how to
use NetWorker with DD Cloud Tier devices.
defined in the Action resource. Additionally, the Pool resource contains 8.2.x legacy
attributes that provide you with the ability to define backup data criteria for the pool.
How and when NetWorker uses the attributes values defined in the Pool, Action, and
Client resources to determine which backup pool will receive data depends on the
value that you select in the Client Override Behavior attribute of the Action resource:
l Client Can Override—The value in Pool attribute of the client resource takes
precedence over the Destination pool value that is defined in the Action resource.
NetWorker does not use the values that are defined in the Client, Save set, and
Levels attributes of the Pool resources when deciding which pool receives backup
data for a client.
l Client Can Not Override—The value defined Destination Pool attribute in the
Action resource takes precedence over the value that is defined in the Pool
attribute of the Client resource. NetWorker does not use the values that are
defined in the Client, Save set, and Levels attributes of the Pool resources when
deciding which pool receives backup data for a client.
l Legacy Backup Rules—Enabled for migrations only. NetWorker uses the values
that are defined in the Client, Save set, and Levels attributes of the pool resource
to determine which pool receives backup data from a client. The values that are
defined in the Client, Save set, and Levels of the pool resource take precedence
over the Destination Pool value that is defined in the Action resource, and the
Pool value that is defined in the Client resource.
Note: You cannot modify the legacy attributes in the migrated Pool resources.
The following table summarizes how NetWorker determines which pool receives the
backup data, which is based on the configuration of the Action, Client, and Pool
resource attributes.

In this example, NetWorker sends the backup data for SQL_clnt and Exchange_clnt to
App_backups, the pool that is defined in the backup action.
A Protection group contains two clients, SQL_clnt and Exchange_clnt. The workflow
that is associated with the protection group contains a backup action.
In this example, NetWorker sends the backup data for SQL_clnt and Exchange_clnt to
Backups, the pool that matches the level Full backup criteria.
A Protection group contains two clients, SQL_clnt and Exchange_clnt. The workflow
that is associated with the protection group contains a backup action.
In this example, NetWorker sends the backup data for SQL_clnt and Exchange_clnt to
the Default pool because a pool does not exist with legacy attributes that match the
configuration for the backup data.
other criteria to determine which pool of volumes receives the data from a full backup
of the mnd.corp.com client.
The NetWorker Server uses the following media pool selection criteria:
1. Groups attribute (highest precedence)
2. Clients attribute
3. Save sets attribute
4. Levels attribute (lowest precedence)
When data matches the attributes for two media pools, for example, Client and Level,
the data is written to the media pool specified in the Client attribute. For example, in
the case where the data from the client matched the criteria for two different media
pools, the data is routed to the media pool that accepts data from the mnd.corp.com
client.
The following table details the hierarchy that the NetWorker Server uses to determine
media pool selection when a conflict arises. For example, the media pool criteria for
Groups takes precedence over the media pool criteria for Clients, Save sets, and
Levels. If data does not meet the criteria for any customized pool, NetWorker writes
the data to the Default media pool.

Attribute Definition
Auto Media Select this attribute to perform automated media verification
Verify while data is written to a volume labeled for this media pool.
Auto media verification provides more information.
Max parallelism Increase the value to define the maximum number of
simultaneous save streams that NetWorker writes to each
device in the pool. The default value for this attribute is 0,
which means that the attribute has no effect on other
parallelism settings. When you set the Max parallelism
attribute to 1, a prolonged delay might occur between the
backup of save sets. To resolve this issue, increase the Max
parallelism attribute for the pool resource. However, when
you increase the pool parallelism value, the time to recover
data on the volume increases.
Note: For AFTD and DD Boost devices, the Max nsrmmd
count attribute value for a device affects the Max
parallelism attribute. For example, consider an AFTD
device (AFTD_1) that has a Max sessions attribute value
of 20 and a Max nsrmmd value of 4. Now suppose a
backup pool with a Pool parallelism attribute of 1 selects
AFTD_1 . The total number of save sessions that
NetWorker can start for AFTD_1 is 4, one for each
nsrmmd process. Tape and FTD devices can only spawn
one nsrmmd process at a time, so if the previous
example used a tape device, then the total number of
save sessions would be 1.
Attribute Definition
Max volumes Defines the maximum number of recyclable volumes that
to recycle NetWorker can relabel during each automatic relabel
process. The default value is 200.
Recycle start Select this attribute to start the automatic relabel process of
now recyclable volumes for this pool immediately after you create
the pool. The default value is No.
Store index For archive pools only. Select this attribute to configure an
entries archive pool that creates client file index entries for the
archive save sets. Clear this option to configure an archive
pool that will not create client file index entries for the
archive save sets.

12. Optionally, on the Restricted Data Zones tab, from the restricted datazone list,
select the restricted datazone in which to add the pool.
13. Click OK
If any of the settings for a new media pool match an existing media pool, this
message appears:
If this message appears, review the media pool configuration and modify any
overlapping criteria.
14. If you did not select a label template when you create the media pool, a
message appears that tells you that NetWorker creates a label template for the
media pool, click OK.
Auto media verification
If the Auto Media Verify attribute is enabled, the NetWorker server verifies data
written to tape volumes from this media pool. This attribute does not apply to AFTD,
file type and Data Domain devices.
Data is verified by repositioning the tape volume to read a portion of the data
previously written to the media. The data read is compared to the original data
written. This feature does not verify the entire length of the tape.
If the data read matches the data written, verification succeeds.
Media is verified when the following occurs:
l A volume becomes full while saving and it becomes necessary to continue on to
another volume.
l A volume goes idle because all save sets being written to the volume are complete.
When a volume fails verification, it is marked full so that the server will not select that
volume for future saves. The volume remains full until it is recycled or a user marks it
not full. If a volume fails verification while the server is attempting to switch volumes,
all save sets writing to the volume are terminated.
Auto media verification should not be used to verify the integrity of the data written to
the entire tape. To fully verify the data written to the tape, either restore the tape
contents or clone the data.
Automatically relabeling volumes in a media pool
About this task
Automatically relabeling a recyclable volume provides the following benefits:
l You can relabel volumes outside of the backup window without the need for a
scripted solution.
l NetWorker has access to appendable volumes at the time of a backup or clone,
which results in faster backup and clone completion times.
Eligible volumes will not be relabeled if the volume is loaded in a device that is:
l Disabled
l In use by an nsrmmd process (for example, during a restore operation)
l In read-only mode
l Busy
When NetWorker automatically relabels a volume, message to the following appears in
the daemon.raw file on the NetWorker server:

listed above will have the SCSI-3 method applied to them:
l Inquiry data VPD page

l Mode sense page
0x1d, byte 2 bit 0 indicates WORM tape present
Byte 4, bits 0,1: label restrictions include
- 00 indicates no overwriting allowed
- 01 indicates some labels can be overwritten
l Byte 5, bits 0,1: filemark overwrite restrictions
- 0x02: any filemark at EOD can be overwritten except for
the one closest to the beginning of the tape
- 0x03: any filemark at EOD can be overwritten
The WORM and DLTWORM attributes determine whether or not the NetWorker
software will back up to a write once-read many (WORM) tape. You can apply these
tape attributes to any pool.
Note: Various Quantum drive models (SDLT600, DLT-S4, and DLT-V4) have the
ability to create WORM tapes from ordinary blank DLT tapes supported by that
particular drive. You cannot recycle an existing NetWorker tape to create a
DLTWORM volume without first having bulk-erased the tape. When the
DLTWORM attribute is set, labeling one of these drives into a WORM pool causes
the Quantum drive to make the current tape a WORM tape.
Savegroups that belong to pools that have either the WORM or DLTWORM attribute
set, are considered to be WORM savegroups.
How to identify WORM media
Since WORM media cannot be reused, the tapes are uniquely identified as such so
that they are only used when required. As shown in this figure, a (W) is appended to
the volume names displayed in the Volumes window. If a volume is both read-only and
WORM, an (R) is appended to the volume name.
Figure 11 Identifying WORM tapes in the NetWorker Console
Note: Since WORM tapes can only be used once, attempting to relabel a WORM
tape always results in a write protection error. With the exception of pool
selection and relabeling, the NetWorker software treats WORM tapes exactly the
same as all other types of tape.
Attribute Description
WORM pools only hold WORM tape By default, the NetWorker software only
allows WORM tapes into WORM pools.
Deselecting this option lets you add new

option when:
Procedure
1. In the Administration window, click Media.
2. In the left pane, select Media Pools.
3. In the right pane, select the appropriate pool.
4. Right-click and select Properties.
5. Click the Configuration tab and select one of these WORM tape handling

Storage nodes
Storage nodes (including the NetWorker server) are host computers with attached
storage devices. A storage node has the physical connection and ownership of the
attached devices, but the NetWorker server maintains the client file index and media
database. With the NetWorker software, client data can be routed directly to a
storage node’s storage devices without the data first going to the NetWorker server.
A storage node may be a client of the NetWorker server, although this is not a
requirement. However, the storage node must have the NetWorker client software
installed.
From the NetWorker server, typical storage tasks can be performed, such as:
l Mounting and labeling volumes for the storage node devices.
l Configuring NetWorker resources associated with the storage nodes.
Only users who have the Configure NetWorker privilege can add to or change the
configuration of the NetWorker server, media devices, and libraries. The NetWorker
Security Configuration Guide provides more information.
Requirements
To operate the NetWorker software with storage nodes, certain requirements must be
met.
l On UNIX systems, this software must be installed on the storage nodes. The
packages must be installed in the following order:
1. NetWorker client software
2. NetWorker storage node software
l On Windows systems, the Storage Node Option must be installed. The Storage
Node Option installs both the NetWorker client and storage node software.
Licensing
The NetWorker Licensing Guide provides information on NetWorker licensing support
for storage nodes.
To modify the Save Mount Timeout and Save Lockout attributes, perform the
following steps.
Procedure
1. In the server’s Administration interface, click the Devices button.
2. Select View > Diagnostic Node.
3. Right-click the remote device and select Properties.
4. Select the Advanced tab.
5. Modify the attributes as appropriate and click OK.
You can apply this feature to all NetWorker clients or to selected clients. This feature
has two options:
l Max sessions—Distributes save sessions that are based on the setting in the Max
sessions option in the storage node device resource. This is the default
distribution method. The Max sessions option is more likely to concentrate the
backup load on fewer storage nodes.
l Target sessions—Distributes save sessions that are based on the setting defined
in the Target sessions option in each storage node device resource. The Target
sessions option is more likely to spread the backup across multiple storage nodes.
When you select the Max sessions option, the NetWorker server distributes the save
sessions for a client among eligible storage nodes as follows:
1. Identifies the available storage nodes in the NetWorker client’s storage node
affinity list.
2. Uses an available device on the first storage node in the list that is working below
its Target sessions level.
3. When all devices on the first storage node are running at their target sessions level
but some are running below their max sessions level, then NetWorker uses the
least loaded device.
4. Continues until all available devices on all storage nodes in the client’s storage
node affinity list are in use.
When you select the Target sessions option, the NetWorker server distributes save
sessions among eligible storage nodes as follows:
1. Identifies the available storage nodes in the storage node affinity list for the client.
2. Uses an available device on the first storage node in the list that is working below
its Target sessions level.
3. When all devices on the first storage node are running at their target sessions
levels, continue to the next storage node even if some devices are running below
their max sessions level.
4. When all devices on all eligible storage nodes are running at their target sessions
level, use the least loaded device that is running below its max session value.
5. Continues to send data to the least loaded device that is running below the max
session value, until all devices on all available storage nodes are running at their
max session levels.
Note the following performance considerations for storage node load balancing:
l Depending on the configuration of the backup environment, there is a potential to
shorten the backup times by using the device Target sessions option rather than
the device Max sessions option. However, using the device Target sessions
option with the checkpoint restart feature can result in slower recovery times
because a single save set is more likely to be spread across multiple storage nodes.
l It is recommended to use the default values for Max sessions as lowering these
values can impact performance.
l Each NetWorker client has a storage node affinity list. The Save sessions
distribution feature can only distribute a backup session for a client to multiple
storage nodes when the client resource has two or more storage nodes in its
storage node affinity list. The storage node affinity list is specified on the Globals
(2 of 2) tab in the NetWorker Client Properties window.
l If you select Max sessions, then you can still override this value for selected
NetWorker client resources by setting the Save session distribution attribute
in the client resource.
5. Click OK.
Multiplexing
Multiplexing is the ability to write multiple data streams simultaneously to the same
storage device. It is often more efficient for the NetWorker server to multiplex
multiple save sets to the same device. There are also times when limiting the number
of data streams to a particular device improves performance of the NetWorker
environment.
Use the Target sessions, Max sessions, and Pool parallelism attributes to increase or
limit the number of data streams that NetWorker writes to a device.
Target sessions
Use the Target sessions attribute on the Configuration tab of the Device resource to
define the optimal number of backup sessions to assign to an active device.
Target sessions is not a hard limit; to set a hard limit for the number of sessions that a
particular device can accept, use the Max sessions attribute.
The Target sessions attribute aids in load balancing devices by determining when the
NetWorker software should write save streams to a device.
When a save session starts, the following actions occur:
l If a device is already receiving the number of backup sessions determined by the
target sessions value, the NetWorker server uses the next underutilized device for
the backups.
l If all available devices are receiving the number of backup sessions determined by
their target sessions value, the NetWorker server overrides the set value and uses
the device with the least activity for the next backup session.
Because it is often more efficient for the NetWorker server to multiplex multiple save
sets to the same device, rather than write each save set to a separate device, the
NetWorker server attempts to assign to each device a number of save sets, up to the
value of target sessions, before assigning a save set to another device.
NOTICE When the NetWorker software assesses how many devices need to be
involved in multiple save streams assignments with the same storage node, the
device with the lowest target session value is used as a reference.
Max sessions
The Max sessions attribute on the Configuration tab of the Device resource defines
the maximum number of save sessions for a device. The max sessions value is never
less than the target sessions value. It is recommended to use the default values for
Max sessions as lowering these values can impact performance.
left unattended by running processes. If Dynamic nsrmmds is set to No, then the
NetWorker starts all available nsrmmd processes. Static mode along with the “mmds
for disabled devices” option provides greater control on the nsrmmd firewall ports.
They ports are attended by running processes.
Note: You must ensure that the sum of storage node devices nsrmmds count
should not exceed 655.
AFTD
Advanced file type devices (AFTDs) support concurrent backup and restore
operations and require the NetWorker DiskBackup Option (DBO) license. AFTDs are
supported for the following configurations:
l A local disk on a NetWorker storage node.
l A network-attached disk device that is NFS-mountable to a NetWorker storage
node running a Linux or UNIX operating system.
l A network-attached disk device that is CIFS-mountable to a NetWorker storage
node running on Windows.
The Client Direct feature enables NetWorker clients to back up directly to AFTDs over
a CIFS or NFS network, bypassing the storage node. For Client Direct backups, the
storage node manages the devices but does not handle the backup data unless the
Client Direct workflow is not available.
DD Boost devices
DD Boost devices reside on Data Domain storage systems that have the DD Boost
features enabled. These devices are similar to AFTDs except they store backup data in
a highly compressed and deduplicated format. The DD Boost API accesses the DD
Boost devices over a network. NetWorker can perform DD Boost backups through
either the NetWorker storage node workflow or the Client Direct file access workflow.
The Client Direct workflow enables NetWorker clients with distributed segment
processing (DSP) and network access to deduplicate their own backup data and send
the data directly to the DD Boost devices. This method bypasses the storage node and
frees up network bandwidth. The storage node manages the devices but does not
handle the backup data workflow if the Client Direct workflow is available.
If Client Direct backup is not available, NetWorker automatically routes the backup
through the storage node where it is deduplicated and sent to the DD Boost devices
for storage. Restore operations work similarly. If Client Direct is not available for a
restore, then NetWorker performs a traditional storage node recovery.
This guide does not cover DD Boost operations. The NetWorker Data Domain Boost
Integration Guide provides details on DD Boost devices
Example environment
The following figure shows various backup-to-disk options deployed in a mixed
operating system environment.
l Linux/UNIX Storage Node A writes its backups to either of the following:
n The AFTD through an NFS connection to Disk Device 1.
n The AFTD on Local Disk 1.
l Windows Storage Node B uses a CIFS connection to back up to the NAS AFTD on
Disk Device 2.
l Data Domain system C writes its backups to a DD Boost device on Local Disk 2.
l Archive operations are not currently supported for Client Direct backups.
\\fileserver\aftd1
fileserver:/aftd1
l If you are setting up a UNIX/Linux storage node, specify the NFS path first.
For example:
fileserver:/aftd1
\\fileserver\aftd1
The following figure shows an example set of paths for a CIFS AFTD.

d. Click OK.
4. In the navigation tree, right-click Devices, and select New Device Wizard.
5. In the Select the Device Type window, select AFTD and click Next.
6. In the Select Storage Node window, specify the path to the storage directory
that will contain the AFTDs.
a. In the Storage Node list, select the storage node that you will use.
b. If the directory for the intended AFTDs is on a different storage node or a
remote storage system, select Device storage is remote from this Storage
Node and type the Network Path of the remote host directory that will
contain the devices.
For example, if the storage node is a Microsoft Windows system and you use
a CIFS AFTD on a remote storage system host, this path could be something
like the following:
\\dzone1_storhost2.lss.corp.com\share-1
This storage path is not a device. It is the directory location in which the
shared devices are to be created.
7. In Browse or Manual, select which option you will use to specify the pathnames
of the devices:
l Browse Storage Node or network path. The next wizard step will prompt
you to browse and add the devices.
l Manually enter local or remote device paths. Select this to skip the
browse step and manually type unique names for the devices you want to
add:
n For remote devices, type the device paths relative to the Network Path
that you specified for the storage directory. For example:
cifsaftd-1
cifsaftd-2
n For local devices, type the absolute paths to these devices. For example:
C:\cifsaftd-1
C:\cifsaftd-2
Multiple devices for a single volume configuration on page 122 provides
details for shared volumes.
8. If the storage host is remote from the storage node, in the Authentication
area, type the appropriate Username and Password to access the storage
directory.
9. Click Next.
10. If you selected the Browse option in the previous window:
a. In the Select the Device Path window, verify that the storage node shows
the path of a storage directory.
b. Add devices to the storage directory by clicking New Folder and typing
unique device names. For example:
cifsaftd-1
cifsaftd-2
c. If Client Direct backup will be used, follow the details in Considerations for
Client Direct clients on page 109.
d. In Target Sessions specify the number of sessions that a nsrmmd data
mover process on the device will handle before another device on the host
will take the additional sessions. Use this setting to balance the sessions
among nsrmmd processes.
If another device is not available, then another nsrmmd process on the same
device will take the additional sessions.
Typically, set this attribute to a low value. The default value is 4 for AFTDs.
It may not be set to a value greater than 60.
e. In Max Sessions specify the maximum number sessions the device may
handle. If no additional devices are available on the host, then another
available storage host takes the additional sessions, or retries are tried until
sessions become available.
The default value is 32 for AFTDs, which typically provides best
performance. It cannot be set to a value greater than 60.
Note: The Max Sessions setting does not apply to concurrent recover
sessions.
f. Click Next.
12. In the Label and Mount device window, if you select the Label and Mount
option, specify the attributes for:
l Pool Type.
l Pool to use.
d. Click OK.
4. In the navigation tree, right-click Devices and select New.
The Create Device window opens, with the General tab selected. The Identity
area might show a default device name in the Name field.
rd=remote_snode_hostname:device_name
For example:
rd=snode-1:aftd-1
NFS_host:/path
where:
l NFS_host is the hostname of the NFS file server
l path is the NFS-mountable path that is exported by the file server
This format is required to allow Client Direct access for Windows or non-
root UNIX clients.
Note: Non-root Client Direct access to an NFS AFTD is supported
only with the NFSv3 protocol and AUTH_SYS authentication on the
NFS host. For Client Direct access to an AFTD when the backup
client is able to run as root on the AFTD host, provide a mount point
or automounter path.
/mnt/aftd-1
/net/storho-1/snode-1/aftd-1
where:
n aftd-1 is the storage device directory name
n storho-1 is the storage system hostname
n snode-1 is the storage node hostname
The first path enables the storage node to access the device via its
defined mount point. The second path enables Client Direct clients to
use the automounter path to directly access the device, bypassing the
storage node.
6. In the Status area, ensure that the Auto Media Management tape feature is
not enabled.
7. In the Cleaning area, leave the options for cleaning at their default (disabled)
settings, so that automatic cleaning is not invoked.
8. Select the Configuration tab.
9. In the Save Sessions area, set the number of concurrent save sessions
(streams) and the number of nsrmmd (data mover) processes the device may
handle:
l Target Sessions is the number of sessions that a nsrmmd process on the
device will handle before another device on the host will take the additional
sessions. Use this setting to balance the sessions among nsrmmd processes.
If another device is not available, then another nsrmmd process on the same
device will take the additional sessions.
Typically, set this attribute to a low value. The default values are 4 for
AFTDs and 6 for DD Boost devices. It may not be set to a value greater than
60.
Multiple devices for a single volume configuration on page 122 provides
details on volume sharing.
l Max Sessions is the maximum number sessions the device may handle. If no
additional devices are available on the host, then another available storage
host takes the additional sessions, or retries are attempted until sessions
become available.
The default values are 32 for AFTDs and 60 for DD Boost devices, which
typically provides best performance. It cannot be set to a value greater than
60.
The Max Sessions setting does not apply to concurrent recover sessions.
l Max nsrmmd count limits the number of nsrmmd processes that can run on
the device. Use this setting to balance the nsrmmd load among devices. The
default value is 4.
To modify this value, first adjust the sessions attributes, apply, and monitor
the effects, then update max nsrmmd count.
At least one nsrmmd process is reserved for restore or clone operations.
10. In the Local Backup area, leave Dedicated Storage Node at No (the default).
11. In the Remote Host area, if an NFS path is specified in the Device Access
Information, then type a Remote User name and Password.
The remote username is the name of the user on the NFS server. It is
recommended that you also specify the numeric user id (UID) of that user. Do
this by appending a colon (:) and the UID after the username, for example,
user_name:4242.
Note: If the device username is changed after labeling, manual action may
be required to change the owner of all files and directories in the AFTD.
NetWorker will try to perform this automatically during the next operation,
however the ability to do so depends on the security configuration of the
file server where the AFTD storage resides.
d. Click OK.
4. In the navigation tree, right-click Devices and select New.
The Create Device window opens, with the General tab selected. The Identity
area might show a default device name in the Name field.
rd=remote_snode_hostname:device_name
For example:
rd=snode-1:aftd-1
E:\aftd-1
\\snode-1\aftd-1
The first path enables the storage node to access the device via its local
drive. The second path enables Client Direct clients to access the device
directly, bypassing the storage node.
l For a CIFS-mounted AFTD, specify the complete paths of the directory
that is created by using the Universal Naming Convention (UNC), for
example:
\\CIFS_host\share-point-name\path
6. In the Status area, ensure that the Auto Media Management tape feature is
not enabled.
7. In the Cleaning area, leave the options for cleaning at their default (disabled)
settings, so that automatic cleaning is not invoked.
8. Select the Configuration tab.
9. In the Save Sessions area, set the number of concurrent save sessions
(streams) and the number of nsrmmd (data mover) processes the device may
handle:
l Target Sessions is the number of sessions that a nsrmmd process on the
device will handle before another device on the host will take the additional
sessions. Use this setting to balance the sessions among nsrmmd processes.
If another device is not available, then another nsrmmd process on the same
device will take the additional sessions.
Typically, set this attribute to a low value. The default values are 4 for
AFTDs and 6 for DD Boost devices. It may not be set to a value greater than
60.
Multiple devices for a single volume configuration on page 122 provides
details on volume sharing.
l Max Sessions is the maximum number sessions the device may handle. If no
additional devices are available on the host, then another available storage
host takes the additional sessions, or retries are attempted until sessions
become available.
The default values are 32 for AFTDs and 60 for DD Boost devices, which
typically provides best performance. It cannot be set to a value greater than
60.
The Max Sessions setting does not apply to concurrent recover sessions.
l Max nsrmmd count limits the number of nsrmmd processes that can run on
the device. Use this setting to balance the nsrmmd load among devices. The
default value is 4.
To modify this value, first adjust the sessions attributes, apply, and monitor
the effects, then update max nsrmmd count.
At least one nsrmmd process is reserved for restore or clone operations.
10. In the Local Backup area, leave Dedicated Storage Node at No (the default).
11. In the Remote Host area, if a network path is specified in the Device Access
Information, then type a Remote User name and Password.
12. Click OK when the configuration is complete.
13. If a new password for an AFTD is provided, unmount and re-mount the device to
ensure that the change takes effect.
remote storage nodes, the Name attributes for the three devices, each created
separately, might be specified by different aliases as follows:
aftd-1a
rd=dzone1-sn2:aftd-1b
rd=dzone1-sn3:aftd-1c
The Device Access Information for each of these aliases would specify a single
directory that must be specified as a valid complete path. For example, if a directory is
named “aftd-1” on the storage host named “storho1,” the path might be specified as
follows:
l If the storage node uses an automounter:
/net/storho1/dzone1/aftd-1
l If the storage node uses an explicit system mountpoint, you might specify one of
the following paths:
n /mnt/storho1/dzone1/aftd-1
n /mnt/dzone1/aftd-1
n storho1:/dzone/aftd-1
2. In the Pools field, select the media pool to be used for the device.
A label for the storage device is generated and displays in the Volume Label
field. The label name is based on the label template for the selected pool.
It is recommended to use a pool that is dedicated to AFTD backup devices only.
Immediately following the message, the action that is associated with the "Filesystem
Full — Recover adv_file Space" notification occurs. By default, the action for this
notification uses the nsrim command to delete expired save sets. If enough space is
cleared, the backup continues. If the recycle setting for the volume is manual, then the
expired save sets are not removed from the volume.
The AFTD deletes expired save sets depending on the retention policy and the recycle
setting. If sufficient storage space is not available after 10 minutes from when the
expired savesets begin deletion, the associated "Filesystem Full—Waiting for adv_file
Space" notification action occurs. By default, an email notification is sent to the root
user on the NetWorker server on UNIX and Linux, and a message is logged in the
media log file in NetWorker_install_path\logs on Windows.
When the notification is sent, and the message is logged in the media log file, the
backup stops until space is available for the backup to continue. You can create
customized notifications to change and expand how the NetWorker software behaves
when an "AFTD Filesystem Full" notification occurs. Custom notifications can also run
custom scripts and other programs to expand the capacity of existing AFTDs.
The chapter "Reporting NetWorker Datazone Activities" provides more information
about how to configure notifications.
In the Console Administration interface, the AFTD Percentage Capacity displays in the
Configuration tab of the Properties window of a device, when Diagnostic Mode is
enabled.
To enable Diagnostic Mode, select View > Diagnostic Mode.
NOTICE If your device uses compression or deduplication, you can still use the
AFTD Percentage Capacity attribute however, the device will be marked as having
reached its threshold prematurely. In this case, there will be more unused space
on the disk than expected. This is because the threshold limit is based on the
amount of data being protected without accounting for the effect of compression
or deduplication.
Disabling a device
Disabling a device prevents further operation of the device. The device may be re-
enabled to restore old data, which is retained but not active.
Procedure
1. In the NMC window for your NetWorker server, click the Devices view and
select the Devices folder in the navigation tree.
2. In the Devices table, right-click the device to be disabled and select Unmount.
3. Right-click this unmounted device and select Enable/Disable to disable.
4. Inspect the Enabled column of the table to verify that the device is disabled.
Deleting a device
The procedure for deleting a device includes an option for also erasing the volume
(access path) that stores the device’s data. The volume can be erased only if no other
device in the system shares the volume.
About this task
Procedure
1. In the NetWorker server Device view, click Devices in the navigation tree.
2. In the Devices table, right-click the device to be removed and select Delete.
A confirmation window appears.
l Perform concurrent recoveries from the command line by using the recover
command, either by using multiple -S options to identify multiple save sets, or
running multiple recover commands concurrently.
When you recover data from an AFTD, NetWorker recovers the save sets
concurrently. You can recover multiple save sets to multiple clients simultaneously and
you can clone save sets from an AFTD to two different volumes simultaneously.
b. In the Data Domain DDBoost Username field, type the username of the
Data Domain user.
c. In the Data Domain DDBoost Password field, type the password of the
Data Domain user.
In DDOS 6 and later, the default password expires in 90 days. To receive
system alert reminders for password change, run the command user
password aging set <boost_user> max-days-between-change 99999.
b. Under Pool, perform one of the following tasks to select the pool:
l Select Create and use a new pool, and type the pool number in the text
box.
l Select Use an existing pool, and select the pool from the drop-down list
box.
The inquire command and the Scan for Devices operation do not detect more than 128 tape
devices
By default, the Linux st kernel module only configures up to 128 SCSI tape devices
(/dev/nst).
When the number of SCSI tape devices exceeds the kernel value ST_MAX_TAPES, the
following error may appear in the /var/log/messages operating system log file:
st:Too many tape devices (max. 128)
The inquire command or the Scan for Devices option in NMC only displays the
maximum number of st devices (/dev/nst) defined by the ST_MAX_TAPES value.
To resolve this issue, edit and recompile the st module of the Linux kernel to increase
the maximum number of allowable st devices that are created by the OS to exceed the
default value. The Linux documentation provides details on how to reconfigure,
rebuild, and install the kernel.
As of HP-UX 11iv3, two different addressing modes are supported: LEGACY and
AGILE. The inquire program lists devices using the B.T.L. notation for the LEGACY
addressing mode, for example:
scsidev@B.T.L.
For the AGILE addressing mode, it lists devices using the DSF notation, for example:
/dev/rtape/tape106_BESTnb
The following error message may appear when you use the scanner -i command to
label the tape when unsupported media is used:
scanner: error, tape label read, No more processes (11)
scanning for valid records …
read: 0 bytes
read: 0 bytes
read: 0 bytes
Note: You can manually change the mode of a volume to recyclable. Changing the
volume mode on page 529 provides information about changing the mode of a
volume.
You can configure a media pool to automatically relabel recyclable volume at a user
defined time and interval. Automatically relabeling volumes in a media pool on page 93
provides more information about configuring the automatic relabel process for
recyclable volumes in a media pool.
VTL licensing
The NetWorker Licensing Guide provides information about NetWorker licensing
support for a Virtual Tape Library.
(max sessions=4) results in deduplication ratios that are 12%-24% below the non-
multiplexed rate (max sessions=1).
l Typically, deduplication ratios are initially low when you increase max sessions and
device block size due to re-priming and re-analysis overhead, following which
efficiency improves.
l Heavily used Data Domain systems, with 75% or more disk space that is already
used, can suffer impaired performance when used with multiple sessions.
l As a best practice, do not use client-side or server-side encryption during backup
to the Data Domain system.
Note: If you shut down the NetWorker server in step 1, you can run the
nsradmin command with the -d resdir option. This option uses the
NetWorker resource database, resdir, without opening a network
connection.
For example, on UNIX/Linux or Microsoft Windows systems, run the following
command:
nsradmin -i input_file.txt
where input_file.txt is a text file that contains the following lines that you can
customize to the own environment:
option regexp: on
. type: nsr device; media type: LTO Ultrium-3; media family:
tape; name: /dev/rmt*
update max sessions: 4; target sessions: 4; device block size:
512KB
touch /nsr/debug/nibmp
touch /nsr/debug/nibmp_My Pool
Persistent binding
Persistent binding guarantees that the operating system always uses the same SCSI
target ID for SAN devices, regardless of reboots or other events, by statically mapping
a target's WWN address to a desired SCSI address. On some operating systems, this
is done by default, while on others it has to be set manually. The operating system
documentation provides further information.
In most cases, persistent binding should also be set on the Host Bus Adapter (HBA) by
using the configuration utility that comes with the Fibre Channel HBA. The HBA
device driver documentation provides details.
Persistent binding is required for consistent library operations within NetWorker,
because the NetWorker server communicates with the library controller over a SCSI
address that is chosen during initial library configuration. If the SCSI address changes,
the library will become unavailable. In this case, disable the library and change the
“control port” address to reflect the new SCSI address of the library controller.
If devices have already been configured in NetWorker prior to enabling persistent
binding on the host, delete existing devices from the library resource and perform a
re-scan of devices followed by a reconfiguration of the tape library.
Persistent naming
Persistent naming is used to ensure that the operating system or device driver of a
server always creates and uses the same symbolic path for a device (referred to as
device file).
After you create persistently named device files and they are present on the host,
enable the Use persistent names option when scanning for tape devices from the
NetWorker Management Console.
If devices have already been configured in NetWorker prior to enabling persistent
naming on the host, delete existing devices from the library resource and perform a
re-scan of devices followed by a reconfiguration of the tape library.
Configure libraries
A library resource must be created on a storage node for each library, including silos,
that you want to use with NetWorker. Because the NetWorker server is also a storage
node, this procedure applies to a NetWorker server and all storage nodes. You can
configure a library either automatically with the Configure All Libraries wizard or
manually with the user interface.
Before you create devices, you must create the storage node that will manage the
devices. Storage nodes on page 98 provides details. When you create the new
devices, you can use NetWorker to perform a device scan, which searches for new
devices across multiple storage nodes.
NetWorker can only automatically create tape devices that have serial numbers. Use
the inquire or sn commands to determine if a device returns a serial number. UNIX
man page and the NetWorker Command Reference Guide provides detailed information
about how to use the inquire and sn commands.
NetWorker can automatically configure the following library types:
l SCSI
l NDMP
l ACSLS Silo
Use the jbconfig command to configure a library that contains tape devices or a
robotic arm that does not have serial numbers. Use the jbconfig command to
configure IBM tape libraries that are controlled through the use of the IBMs tape
driver. This is because the device autodetection code uses the internal lus driver to
control libraries.
Note: Before you create devices on a storage node, update the devices to the
most recent firmware and driver versions.
l A specific network interface can be used between the NetWorker server and the
storage node when scanning for devices. Identifying a specific network interface
for device scan operations on page 145 provides more information.
Procedure
1. In the Console window, click Enterprise.
2. In the navigation tree, select a NetWorker server.
3. In the Name column of the Host detail table, double-click NetWorker. The
NetWorker Administration window for the selected server opens. Note that
while multiple NetWorker Administration windows can be open
simultaneously, each one displays information about only one host or server.
4. In the Administration window, click Devices.
5. In the navigation tree:
a. Right-click the server name, and select Scan for Devices.
b. Click the storage node to be scanned.
c. If the appropriate storage node is not listed, click Create a New Storage
Node.
d. When creating a new storage node, replace the default value in the Name
field with the fully-qualified domain name or short name of the new storage
node.
e. Fill in any required information, such as whether to scan for SCSI or NDMP
devices and whether to search all LUNs.
f. Click Start Scan. To monitor the scan activity, click Monitoring, then select
the Log tab. Any relevant status information is displayed there.
6. Return to the Devices navigation tree to view the refreshed device information
(configured and unconfigured):
l To display SCSI and NDMP libraries available to the NetWorker server,
select Libraries in the navigation tree. Any available library or silo appears in
the Libraries detail table.
l To display stand-alone devices available to the NetWorker server, select
Devices in the navigation tree. Any available stand-alone device appears in
the Devices detail table, along with devices available in libraries.
l To display the libraries and devices that are available to a storage node,
select the storage node in the navigation tree. Available storage nodes
appear in the table. Double-click a storage node to see its details, along with
the devices that are available in the storage node.
manually. The NetWorker software scans the barcode label during the labeling
process and updates the media database with the new volume name and its
associated barcode label.
l Do not use identical barcode labels for any of the NetWorker volumes. The use of
identical labels defeats the purpose of using barcode labels, which is to facilitate
the inventory process and ensure label accuracy.
l Volume names must be unique on the NetWorker server. Give each volume a
unique volume label. If a second volume is labeled with an existing barcode label
and the Match Barcode Labels attribute in the library’s properties is enabled, the
NetWorker server displays an error message and does not allow the second
volume to be labeled. The error message identifies the library slots containing the
two volumes with identical labels and the barcode label.
To correct this problem, either apply a different label to one of the volumes and
restart the labeling process, or disable the Match Barcode Labels attribute in the
library’s properties while labeling the second volume.
l It is not necessary to label existing volumes with barcode labels if they are stored
in a vault or offsite for long periods. These volumes are rarely, if ever, inventoried.
l Before using barcode labels on existing volumes, affix the barcode labels to them.
Then, load and mount each volume individually, so that the NetWorker server can
match the barcode label with the existing volume label.
l Record the volume label on the tape.
l A variety of barcode labels can be purchased from third-party vendors. Choose
from among numeric labels, alphanumeric labels, or a special combination of
numbers and characters. Furthermore, barcode labels can be ordered to match a
current volume labeling scheme.
l Use a consistent labeling scheme. If volumes are labeled with the server name and
an extension such as “001,” order a range of labels starting with
“server_name.001” and ending with “server_name.100”, or as wide a range as
necessary. Instructions for barcode labels should be provided with the library
hardware documentation. Contact the hardware manufacturer with questions
about barcode labels. A consistent labeling scheme helps better organize and track
volumes. It also facilitates the inventory process if all of the volumes, use barcode
labels.
Labeling volumes
The NetWorker software applies a label template to create a unique internal label for
each volume. The label corresponds to a pool and identifies the pool for the volume
during backup and other operations.
Several preconfigured label templates are supplied with the NetWorker software. You
cannot delete these preconfigured label templates. Naming label templates on page 79
provides more information.
When you label a volume, the labeling process:
l Writes a label on the volume.
l Adds the volume label to the media database.
l Prepares tape media to have data written to it.
When you re-label tape, the data on the tape is effectively gone.
During data recovery, the server requests the volume that contains the required data,
identifying the required volume by the name with which it was labeled.
Label templates
Several preconfigured label templates are supplied with the NetWorker software.
These preconfigured label templates cannot be deleted. Naming label templates on
page 79 provides more information about label templates and preconfigured label
template.
Labeling or re-labeling library volumes
Labeling volumes in a library is time-consuming, so consider labeling volumes before it
is time to back up or recover files. When a volume is re-labeled, that volume is
initialized and becomes available for writing again.
Procedure
1. In the Administration window, click Devices.
2. In the left pane, select Libraries.
A list of libraries appears in the right pane.
3. Right-click the library and select Label.
Details for the selected library appear, including divided tables for devices and
slots. The Label Library Media dialog box also appears.
4. From the Target Media Pool list, select the pool for the volume.
The pool determines the label template that is used to label the volume.
5. To require manual recycling of the volume, select Allow > Manual Recycle.
With manual recycling, the volume is not automatically marked as recyclable
when all save sets expire. You must manually mark the volume as recyclable.
NOTICE A volume that has been set to manual recycle retains that setting,
even after the volume is re-labeled. You must explicitly reset the volume to
automatic recycle by right-clicking the volume in the Media window,
selecting Recycle, and then selecting the Auto option.
Reconfiguring a library
Use this procedure to reconfigure a tape library.
Before you begin
To reconfigure a library or to add or remove access paths to the devices in a library,
use an account with the Configure NetWorker privilege. This includes access paths
that allow libraries to be shared.
About this task
Note: The following procedure does not support adding NDMP devices to a non-
NDMP library if both the NDMP server and the NetWorker storage node are on
the same host. Instead, use the jbedit command.
Procedure
1. Run Scan for Devices, in case a device path has been added to, or removed
from, the library since the latest scan.
2. In the server’s Administration window, click Devices.
3. Select Libraries in the navigation tree. The Libraries detail table appears.
4. In the navigation tree, right-click the entry for the library to be reconfigured, or

necessary, or using the buttons at the right side of the area (Check All, Clear
All, Reset).
Drives that are already configured to be used by the library display check marks
in the boxes that are adjacent to their names:
Reset a library
A library must be reset each time the library and the NetWorker software become out
of sync. A library reset can be done using either the Administration interface or the
command prompt.
Resetting a library in the Administration interface
To reset a library in the Administration interface:
Procedure
1. In the Administration window, click Devices.
2. Open the Libraries folder in the navigation tree. The Libraries detail table
appears.
3. Select a library in the navigation tree or double-click a library in the Libraries
detail table to open the double-paned Library Operations view.
The library’s drives are listed in the pane on the left in the Device column. The
library’s slots are listed in the pane on the right.
4. Right-click a library in the Device column, and select Reset. You are prompted
to reset the library.
5. Click Yes. The Library Operation window appears and displays this message:
6. Click OK.
Deleting libraries
The library's devices remain, and can still respond to NetWorker operations (such as
monitoring, labeling, deletion, and so on) after the library definition is deleted. A
deletion of a library deletes the library, not its devices.
About this task
Procedure
1. In the server’s Administration interface, click Devices.
2. Select Libraries in the navigation tree. The Libraries detail table appears.
3. In either the navigation tree or in the Libraries detail table, right-click the entry
for the library to be deleted, and select Delete.
4. When prompted, click Yes.
This message appears:
"Are you sure you want to delete this jukebox? If so, please
re-attempt
deletion within a minute."
Library notifications
The NetWorker server uses notifications to send messages about NetWorker events.
Several preconfigured notifications, such as the following, provide information about
various situations:
l Volumes in the library are 90% full
l Library needs more volumes to continue
l Library has a mechanical problem
l Library device needs cleaning
l Cleaning cartridge needs attention.
The NetWorker software automatically mounts a required volume as long as the
volume is loaded in the library. If a recovery operation requires a volume that is not
loaded in the library, the Tape mount request 1 notification sends an alert to
Monitoring > Alerts, with a request to do something with a specific volume.
After a library problem is corrected, it might be necessary to mount a volume so the
NetWorker server can continue to back up or recover files.
for adding and removing volumes and may cause the server information to become out
of sync with the library. Normally, you should use the NetWorker server procedures
for adding and removing media, rather than the library's front panel display. This is
more efficient and guarantees that the server and the library will be in sync.
About this task
If it is necessary to use the library's front panel display to add and remove volumes.
Note: When a library is partitioned, the NetWorker software does not become
aware of the partitioning. This means that the entire physical library will be
disabled, not just one partition.
Procedure
1. In the Properties window for the Library, on the General tab, set Status
Enabled to Service.
Note: Putting the library in service mode will cancel all operations or wait
for operations to complete that cannot be canceled, and then put the library
into disabled mode.
2. Once the library is in disabled mode, use the library's front panel to add and
remove tapes.
3. In the Properties window for the Library, on the General tab, set Status
Enabled to Enabled.
4. Inventory the library. Inventorying library volumes on page 160 has information
about inventorying libraries.
c. Click OK.
5. To unmount the volume:
a. Right-click the device or the volume in the double-paned table view of the
library and select Unmount.
l The Library Operation window displays this message:
6. Click OK.
6. In the Devices column, right-click the library in which the volume was manually
inserted, and select Inventory. The Inventory Library window appears.
7. Type the slot number of the volume in both the First and Last field of the Slot
Range.
8. Select Operation Type: either Slow/Verbose (the default) or Fast/Silent.
l When Slow/Verbose is selected, the Supply Input option and icon on the
Operations screen of the Monitoring window can be used to confirm the
choice to relabel a volume. The device path appears in the Device field.
l When Fast/Silent is selected, the Supply Input option and icon are not
available, and relabeling proceeds automatically, without user input. The
device path does not appear in the Device field. Entering user input on page
61 provides details.
9. Click OK.
l The Library Operation window displays this message:
The library operation has started.
l The Monitoring > Operations screen displays its status.
The NetWorker software then inventories the specified slot.
10. Mount the inventoried volume.
NOTICE Unlabeled tapes may not be mounted for inventorying. Unlabeled
tapes can only be mounted to be labeled. An attempt to mount an
uninventoried volume by using unlabeled media results in an I/O error. The
volume will also be ejected.
Library maintenance
Periodically clean a storage library to keep it working correctly. The NetWorker server
provides automatic cleaning of devices located in libraries. The server does not
support automatic cleaning for stand-alone devices. Cleaning is an option set during
configuration.
The service mode feature allows a library to be taken offline temporarily for cleaning
or other maintenance.
Tape alert
The TapeAlert feature provides, among other things, diagnostic information for
devices for which hardware cleaning is enabled.
NetWorker provides the following attributes for tape device cleaning:
l Cleaning required
l Cleaning interval
l Date last cleaned
When the Common Device Interface (CDI) is enabled, TapeAlert attributes provide
tape drive status. SCSI Commands must be selected for the CDI attribute on the
Configuration tab of the relevant device’s Properties. If CDI cannot be enabled,
TapeAlert is not supported.
Devices that are capable of TapeAlert perform constant self-diagnostics and
communicate the diagnostic information via the nsrmmd program to logs that can be
viewed in the Monitoring task.
The following TapeAlert attributes are found in the device’s Properties, on the Volume
tab.
l TapeAlert Critical: Displays critical diagnostic information, such as for media or
drive failure, when user intervention is urgent and data is at risk.
l TapeAlert Warning: Displays a message when the media or device needs servicing.
l TapeAlert Information: Displays status information.
The following table describes the nature of the tape alert levels.
Warning X X
Informative X
The messages indicate tape and drive states related to tape drive read/write
management, cleaning management, or drive hardware errors.
Informative messages
Informative messages indicate status information:
l A data or cleaning tape is nearing its end of life.
l A tape format that is not supported.
Note: When automatic cleaning is enabled, a diagnostic message to indicate
that a drive needs cleaning initiates NetWorker drive cleaning.
Warning messages
Warning messages indicate the following types of drive errors:
l Recoverable read or write errors occurred.
l Media is at end of life.
l Read-only tape format is in the drive.
l Periodic cleaning is required.
Critical messages
Critical messages are warnings that a drive might be disabled and requires immediate
attention to avoid data loss:
l Unrecoverable read or write errors occurred.
l Tape is marked read-only.
l Drive require immediate cleaning.
l Drive is predicting hardware failure.
Informative and warning messages should clear automatically by nsrmmd once the
reported issue is handled.
Critical messages about hardware errors are not cleared by nsrmmd because they
might indicate intermittent hardware problems.
Option Description
-a Add a drive or device.
The NetWorker Command Reference Guide or the UNIX man page provides a detailed
description of the jbedit command, its options, and associated diagnostic messages.
Device ordering
The NetWorker server uses logical device names assigned by the operating system
when communicating with devices. It is possible for the operating system to re-
associate logical device names with the physical addresses of the devices, generally
after rebooting the host or after plug-and-play events. This may cause device
reordering, where the physical device will have a different device filename. As a result,
tape devices configured in the NetWorker software no longer match the names of the
devices as recognized by the operating system.
If device reordering occurs, the NetWorker software is unable to use any affected
drives until the configuration is manually corrected.
The NetWorker server detects device reordering events by comparing the current
serial number of the device to the serial number of the device at configuration. If the
serial numbers do not match, the NetWorker server stops all operations on that device
and an error message will be posted, similar to the alert identified for device serial
number mismatch in the table Preconfigured notifications on page 711. CDI must be
enabled for this functionality. Setting the common device interface on page 172
provides more information about enabling CDI.
Detecting device ordering issues
To determine if there is a problem with device ordering in your environment, you first
determine if the device order that appears in nsrjb output matches the device order
from the inquire and sjisn commands, then verify that the device configuration within
your NetWorker configuration conforms to this.
Procedure
1. Execute the inquire command with the -cl option to determine the device
path, scsi address, and serial number of the device.
2. Execute the sjisn command to determine the current order of the devices:
sjisn scsidev@bus.target.lun
where bus.target.lun is the SCSI address of the robotic arm returned by the
inquire command in step 1, for example, 1.2.0.
3. Match the serial numbers of the devices in the sjisn output to the device names
that correspond to these serial numbers in the inquire -cl output. This will give
you the current device order by device filename.
4. Execute the nsrjb command to determine the order of devices as configured
in NetWorker. Drive entries towards the end of the nsrjb output list the device
order as configured in NetWorker.
5. Compare the device ordering as determined in step 3 and step 4. If the device
ordering in these two steps do not match, the device ordering has changed and
the library will need to be reconfigured.
Drive ordering change corrections
After a drive ordering change has taken place and the NetWorker software is no
longer correctly communicating with devices, you can correct the problem within your
NetWorker configuration by using the NetWorker Console or the jbedit command line
program.
Using NetWorker Console to correct drive ordering changes
You can correct drive ordering changes by using the NetWorker Console.
Procedure
1. Ensure that you have a current backup of the resource database.
2. Delete the library resource in the NetWorker Console. Deleting libraries on page
152 provides details.
3. Rescan the library. Scanning for libraries and devices on page 142 provides more
information.
Using the jbedit command to correct drive ordering changes
You can correct drive ordering changes by using the jbedit command.
Procedure
1. Use the jbedit command with the -d option to delete devices from the
NetWorker configuration.
2. Use the jbedit command with the -a option to add the devices again.
Library configuration using the jbedit command on page 164, or the UNIX man
page for jbedit or the NetWorker Command Reference Guide provides more
information about the jbedit command.
An Event ID for the error is also created, which will be removed along with the alert
when the problem is resolved. You can resolve the problem and clear the error
message.
Procedure
1. Disable the drive.
2. Perform one of the above procedures to correct the problem.
3. Re-enable the drive, and retry the operation that was being performed prior to
receiving the error.
Results
The Alert will be removed and the event dismissed.
Tape drive number reordering (Microsoft Windows only)
If more than one tape drive is attached to the NetWorker server when both the server
and drives are shut down, restart all of the tape drives, either before or immediately
after the NetWorker server is restarted. If Windows does not locate all of its
previously configured tape drives at the time of startup, it automatically reassigns the
tape registry name.
For example, assume that these three tape drives are attached to the server:
l The first one, \\.\Tape0, is a 4 mm tape drive.
l The second, \\.\Tape1, is an 8 mm tape drive.
l The third, \\.\Tape2, is also an 8 mm tape drive.
If only the second and third tape drives are restarted, Windows reassigns the tape
registry numbers so that the second storage device becomes \\.\Tape0 and the third
storage device becomes \\.\Tape1. The tape registry numbers no longer match the
defined storage devices within the NetWorker software. As a result, the server
mishandles the drives and their volumes.
It might be easier to leave a nonoperational drive (device) attached to the server until
a replacement is available. If the drive is removed, the name must be deleted, and then
the new drive must be added.
To disable the drive, select No for the Enabled attribute in the device’s Properties.
Device calibration
For information about the frequency and method for calibrating the loading
mechanism for the device, refer to the library manufacturer’s documentation.
Windows hardware. This could lead to I/O errors in both write and read states on the
device. In order to use both operating systems, it is necessary to determine a block
size that is acceptable to both.
NOTICE In NetWorker 8.0.1 and later, the default block size for an LTO device
increases from 128 KB to 256 KB. When NetWorker labels a new or used volume in
an LTO device and the Device block size attribute of the device is handler default,
the label operation uses a 256 KB block size.
Determining the allowable block size
You can determine the allowable block size by checking the Properties window of a
mounted volume while in Diagnostic Mode.
Procedure
1. In the server’s NetWorker Administration interface, click Devices.
2. Select View > Diagnostic Mode.
3. Open the Libraries folder in the navigation tree and select the drive that
contains the mounted volume with the block size being checked. The drive’s
detail table appears.
4. Right-click the drive in the detail table, and select Properties. The Properties
window appears.
5. Select the Volume tab. In the Loaded Volume area, one of the displayed
volume attributes is the Volume Block Size.
6. Click OK.
Solving block-size compatibility problems
About this task
Note: It is also possible to solve problems with block-size compatibility by
changing the block size for an entire device type. The change, however, must be
made on each storage node where it is to be available. Once the block size is
changed, it affects only those volumes that are labeled after the change. Volumes
can be relabeled to use the new block size, but if they contain data that should be
saved, be sure to clone the data beforehand to a volume that already uses the new
block size.
Procedure
1. In the server’s NetWorker Administration interface, click Devices.
2. Select View > Diagnostic Mode on the menu bar.
3. Open the Libraries folder in the navigation tree and select the drive that
contains the mounted volume with the block size being checked. The drive’s
detail table appears.
4. Right-click the drive in the detail table, and select Properties. The Properties
window appears.
5. Select the Advanced tab. In the Device Configuration area, the currently
configured Device Block Size value is displayed.
6. Select the appropriate Device Block Size value.
7. Click OK.
Setting the block size for a device type
Procedure
1. Change the block size:
l On UNIX, change the block size by setting this environment variable to the
greatest common value for both systems. For example:
where:
n MEDIA_TYPE is the backup device type available to the NetWorker
server (also found in the Media Type attribute on the General tab of the
device’s properties). The media type syntax must be all uppercase, with
underscores (_) replacing blank spaces and hyphens. Therefore, a device
displayed in the NetWorker software as "8mm Mammoth-2" would be
listed as:
8MM_MAMMOTH_2
n value must be a multiple of 32 KB, with a minimum value of 32 KB.
l On Microsoft Windows only, install a later model HBA, or upgrade to drivers
that can support up to 128 KB blocks. Windows also accepts the same
environment variable format as UNIX to set block size.
2. Restart the NetWorker server in order for changed environment variables to
take effect.
Device block size for read and write operations
The block size for a volume is defined during the label operation. The label operation
uses the value defined in the Device block size attribute for the Device or the value
defined by the appropriate block size environment variable.
The block size for both read and write operations uses the block size defined in the
volume header during the label operation rather than the device block size.
Block-size mode (UNIX/Linux only)
Ensure that the block size mode for tape devices that are used with NetWorker
software is set to variable. Otherwise, data recovery might fail. The procedure for
setting the device block size varies depending on the operating system.
The operating system’s documentation provides information about setting the tape
device block size in the operating system.
l NSR_DEV_TAPE_FILE_SIZE_MEDIA_TYPE
l NSR_DEV_LOAD_TIME_MEDIA_TYPE
l NSR_DEV_LOAD_POLL_INTERVAL_MEDIA_TYPE
l NSR_DEV_LOAD_TRY_LIMIT_MEDIA_TYPE
l NSR_DEV_DEFAULT_CAPACITY_MEDIA_TYPE
where:
MEDIA_TYPE is the backup device type available to the NetWorker server.
Note: The media type syntax must be all uppercase, with underscores (_)
replacing blank spaces and hyphens. For example, a device displayed in the
NetWorker software as “8mm Mammoth-2” would be listed as:
8MM_MAMMOTH_2
To determine the media type, right-click the device an select the General tab.
The Media Type attribute contains the media type that should be used in
these environment variables.
NSR_DEV_BLOCK_SIZE_MEDIA_TYPE
NSR_DEV_BLOCK_SIZE_MEDIA_TYPE is organized in units of kilobytes. This
environment variable will cause NetWorker to override the default block-size setting
defined for the tape drive in the operating system. The value set must be a multiple of
32, with a minimum value of 32. Maximums are determined by platform, SCSI driver,
and device.
For example:
NSR_DEV_BLOCK_SIZE_4MM_20GB=64
For information about using this environment variable to set block-size compatibility
between UNIX and Microsoft Windows. SCSI data block size issues between UNIX and
Windows on page 166 provides more information.
NSR_DEV_TAPE_FILE_SIZE_MEDIA_TYPE
NSR_DEV_TAPE_FILE_SIZE_MEDIA_TYPE is organized in units of
NSR_DEV_BLOCK_SIZE_MEDIA_TYPE and is the number of blocks written between
filemarks. These filemarks are used to locate a particular spot on the tape during
recovery, and more filemarks generally lead to faster positioning. For example:
NSR_DEV_TAPE_FILE_SIZE_TZ89=512
On UNIX and Linux platforms, the NetWorker software writes a filemark by closing
and reopening the tape device, which takes one or two seconds. If this value is too
small, throughput could be slowed and recoveries may take longer to complete.
On Microsoft Windows platforms, the NetWorker software writes asynchronous
filemarks. This setting has a minimal effect on performance.
NSR_DEV_LOAD_TIME_MEDIA_TYPE
NSR_DEV_LOAD_TIME_MEDIA_TYPE is the number of seconds that nsrmmd polls
and waits for a drive to become ready after the library inserts a tape into the device.
NSR_DEV_LOAD_POLL_INTERVAL_MEDIA_TYPE is used to set the number of
seconds nsrmmd waits between polls during load time.
If the value of NSR_DEV_LOAD_TIME_MEDIA_TYPE is too short, there could be
unnecessary load failures. If it is too long, then labeling new tapes takes longer than
necessary. The minimum allowable value is 10 seconds. The maximum value is 600
seconds. For example:
NSR_DEV_LOAD_TIME_DTL8000=300
NSR_DEV_LOAD_POLL_INTERVAL_MEDIA_TYPE
NSR_DEV_LOAD_POLL_INTERVAL_MEDIA_TYPE is the number of seconds that
nsrmmd waits between each attempt to read a newly inserted tape. The minimum
allowable value is 1 second, the maximum value is 30 seconds. For example:
NSR_DEV_LOAD_POLL_INTERVAL_DLT=10
NSR_DEV_LOAD_TRY_LIMIT_MEDIA_TYPE
NSR_DEV_LOAD_TRY_LIMIT_MEDIA_TYPE is the number of times that nsrmmd will
attempt to open a drive. The nsrmmd program will poll the drive until the limit set in
NSR_DEV_LOAD_TIME_MEDIA_TYPE is reached. After the limit is reached, it will
retry until the NSR_DEV_LOAD_TRY_LIMIT_MEDIA_TYPE is reached. The default
value and minimum allowable value is 2, the maximum value is 120.
NSR_DEV_LOAD_TRY_LIMIT_DLT=4
NSR_DEV_DEFAULT_CAPACITY_MEDIA_TYPE
NSR_DEV_DEFAULT_CAPACITY_MEDIA_TYPE is the size of the particular tape used
to base the percent full calculation. This variable value has no effect on the actual tape
capacity. Any integer value is allowed, with a KB, MB or GB designation to indicate a
range of values. Any value less than 200 MB will be overridden by the normal default
capacity. There is no obvious maximum, with the only practical limitation being the
actual storage size. For example:
NSR_DEV_DEFAULT_CAPACITY_DTL7000=12GB

l A drive that always reports a fixed number of failures before correctly mounting
and reading a tape, even if the tape is not damaged, can cause a failure loop. In
this example, ensure that the Max Consecutive Errors value is higher than the
number of times that particular drive fails before working correctly.
Re-enabling a device
Once the number of retries equals the Max Consecutive Errors value, the device
becomes disabled. After the problem that disabled the device has been fixed, the

Procedure
1. When the NetWorker computer is idle, remove any volume from the disabled
drive and ensure that the drive is in good working order.
2. In the Administration window, click Devices. The Devices detail table appears.
3. Right-click the drive to be reenabled, and select Properties. The Properties
window appears.
4. In the Status area of the General tab, set Enabled to Yes.
5. Click OK.
1. If the disabled drive is part of a library, it might be necessary to reset the
device. To do this:
6. From the command prompt, change the path to the directory that contains the
NetWorker binaries.
7. Type this command:
nsrjb -HE
NOTICE A device retains it enabled or disabled status in the Properties
window and in the Devices detail table regardless of whether its storage
node is enabled or disabled. Therefore, it is possible that the storage node
Properties window is set to disabled while its devices appear to be enabled
in the GUI.
Silo libraries
This section describes silos and silo devices. Silos and libraries are managed similarly
by NetWorker software.
A silo tape library (STL) is a peripheral that usually contains many storage devices.
Silos libraries have a robotic controller that moves tape media between slots and
devices. Silos do not use a SCSI interface to access and control the media
movements. Media movements are controlled by a separate host that is called the silo
server. The silo server uses silo management software to manage media movement
requests over the network. The silo vendor provides the silo management software.
The silo server cannot be the same computer as the NetWorker server.
The silo can be shared among many applications, systems, and platforms. As with
libraries, silos make data and media operations more automatic. Silos can load, change,
and manage volumes, and clean the devices automatically.
NetWorker only supports silos that use the Automated Cartridge System Library
Software (ACSLS) Manager software.
Tape Library Interface (STLI), which must be installed on the NetWorker server that
uses the silo.
To access the volumes and devices in a silo, the NetWorker server sends a request to
the silo management software, in the form of an STLI call. For example, to mount a
volume in a silo device, the NetWorker media service sends a request to the silo
management software to mount the volume into a particular device in the silo. The silo
server responds to the request and mounts the volume in the requested device.
The silo management software controls many of the operations that NetWorker
software controls with a library. For example, the silo management software keeps
track of the slot where each silo volume resides, and might control the deposit and
withdrawal of volumes, as well as automated cleaning of silo devices.
Installing a silo
Procedure
1. Install the silo management software on the silo server.
2. If required, install the STLI library on the NetWorker server. For more
information, refer to the documentation from the silo vendor.
For example, for a NetWorker server or storage node running Windows to
control an STK silo, the libattach program must be installed.
On UNIX systems, do not install the STLI library because all the necessary
software is installed when the NetWorker software is installed.
3. Ensure that the NetWorker server is properly connected to the media devices in
the silo.
4. Add the silo. Configuring silo libraries on page 175 provides further details.
The Configure All Libraries wizard appears, and allows the user to step
through library configuration, including the following input (some of which is
filled in by default):
l Library type (select STL Silo).
l Adjust the Enable New Device option, if required.
l Current server sharing policy (use maximal sharing with Dynamic Drive
Sharing [DDS]).
l Storage nodes on which the libraries should configure. You can select a
storage node to see its details that are displayed. If the appropriate storage
node is not listed, click Create a New Storage Node. When creating a
storage node, replace the default value in the Name field with the name of
the new storage node:
a. Update storage node properties, if required.
b. Type the Silo Controller count, which sets the number of silos to be
configured for the selected storage node. The default is 1. If a silo count
of greater than one is selected, then a library name and hostname must
be typed for each one.
c. Type the Hostname of the silo controller.
d. (Optional) Use the Test Silo Controller Connectivity button to see
whether the connection to a silo controller works. Use it once for each
silo. If the connection to a given silo fails, an error message appears.
4. Click Start Configuration after filling in the requested information. The
Configuration window displays a message that the Configure All Libraries
process has started, and that the configuration activity can be viewed by
checking the Monitoring > Log screen for status.
5. Click Finish on the Configuration window to close the configuration wizard. If
problems occur during configuration, then the Back button on the
Configuration window becomes active, which allows the user to return to the
input screen to adjust input.
6. Click OK.
7. Repeat all steps for each device to be released.
ENV_VAR_NAME = value
export ENV_VAR_NAME
3. Stop and start the NetWorker server daemons in order for the environment
variables to take effect.
Barcode IDs
A list of available barcode-labeled volumes is available from the silo management
software. Refer to the silo manufacturer’s documentation for how to generate the list
of barcode IDs.
To specify a barcode identifier or template for the volumes from a command prompt,
use the -T option with the nsrjb command. The UNIX man page and the NetWorker
Command Reference Guide provides detailed information about the nsrjb command.
Silo volume allocation
When volumes are added, the NetWorker server is directed to the volumes it can use.
NOTICE Because silos can be used by more than one software application, it is
possible that a different application could read or write to volumes that belong to
the NetWorker software. To prevent this from happening, most silo management
software includes methods to limit access to volumes based on the hostname of
the computer on which various programs run. The NetWorker software does not
provide a method for setting up this sort of protection. The silo management
software must configure it.
The addition of a volume causes the NetWorker software to query the silo
management software to verify that the requested volume exists.
If the volume exists, the volume is allocated to the NetWorker software.
Adding a silo volume
Procedure
1. In the Administration window, click Devices.
2. Open the Libraries folder in the navigation tree. The Libraries detail table
appears.
3. Double-click a silo in the Libraries detail table to open the double-paned library
operations view. The silo’s drives are listed in the Device column, and its slots
are listed in the Slot column.
4. Right-click a silo in the Device column, and select Add. The Add Library
Volumes window appears, with the option to select either Template or List for
barcode selection.
5. Select either Template or List to enter barcode volume identifiers.
l The Template option allows the use of wildcards in creating a list of barcode
IDs. Each entry should be on a separate line. For example, to name four
tapes A01B, A02B, A03B, and A04B, type:
A0
1-4
B
l The List option allows the entry of barcode IDs, separately. Each entry
should be on a separate line. For example, type the name for each tape:
A01B
A02B
A03B
A04B
6. Type the appropriate volume identifiers in the Barcodes field.
7. Click OK (or Cancel, to continue adding to the list).
l Click "+" to add an entry.
l Click "<-" to insert above a highlighted selection.
l Click "-" to delete an entry.
The Library Operation window displays this message:
The library operation has started.
The Monitoring > Operations > screen displays the status.
8. Click OK.
The Library detail table displays the added volumes.
Inventory silos
Taking inventory of the volumes in a silo ensures that the mapping between slot
number and volume name is correct, or reconciles the actual volumes in a silo with the
volumes listed in the NetWorker media database.
The slot number of a silo volume is not a numbered slot inside the silo, as it is in a
library. The slot number of a silo volume is the number of the volume’s position in the
list of volumes in a silo.
The tasks for inventorying volumes in a silo are the same as those for a library.
Inventorying library volumes on page 160 provides information about inventorying a
library.
The NetWorker software examines all of the volumes in the silo and compares the new
list of volumes to the NetWorker media database. Then the NetWorker software
produces a message listing any volumes located in the silo that are not in the media
database.
When the NetWorker software inventories a silo, the silo’s barcode label reader reads
the barcode labels on the outside of each volume. When a barcode matches an entry
in the NetWorker media database, the volume does not need to be loaded. The
inventory proceeds rapidly. If, however, the NetWorker software reads a barcode that
does not match any of the entries in the media database, the volume must be mounted
and read in order for a proper inventory to be taken.
Troubleshooting a silo
If the particular silo model does not automatically deposit the volume, then place the
volumes in the insert area, right-click the volume, and select Deposit.
To perform the Deposit and Add operations from a command prompt:
l On silos that require manual depositing, type nsrjb -a -T tags -d
l On silos where the silo management software deposits volumes automatically,
such as StorageTek silos, type
nsrjb -a -T tags
where:
n tags specifies the tags or barcodes of volumes in a remote silo.
n -d performs the manual deposit.
NetWorker software interactions with a silo on page 173 provides more information on
STLIs.
Deallocating (removing) silo volumes
When an STL volume in a silo is no longer needed, the volume can be deallocated from
the silo. Deallocation is basically the same operation as removing a volume from a
library. Although the volume cannot be loaded by the robotic mechanism, the entries
in the NetWorker media database remain intact. If the volume is allocated again,
NetWorker software can retrieve the data from it later.
About this task
Use deallocation when the silo license limits the number of usable slots, or when data
is moved offsite for safer storage. When the license limits the number of slots, it might
be possible to leave the volumes in the silo, if it is certain that the volumes will not be
used by another application. That way, the volumes can easily be added again when
the data on them must be accessible.
The allocation operation is not automatic. The volumes must be manually allocated
again and reinventoried to let the NetWorker server access the data. If the volume is
to be removed from the silo for offsite storage, it must be removed with NetWorker
software and then ejected from the silo by using the silo management software.
Procedure
1. Unmount the volume from the device. Volume mounting and unmounting on
page 154 provides instructions on unmounting volumes.
2. In the Administration window, click Devices.
3. Open the Libraries folder in the navigation tree. The Libraries detail table
appears.
4. Double-click a silo in the Libraries detail table to open the double-paned library
operations view. The silo’s drives are listed in the Device column.
5. Right-click a silo in the Device column, and select Remove.
The Remove Library Volumes window appears, with the option to select either
Template or List for barcode selection.
NDMP libraries
NDMP libraries or devices are accessed by using the NDMP protocol and are typically
used by network attached storage (NAS) systems. These devices do not allow direct
access to control from the host operating system. Control and data movement is
performed over the network by using the NDMP protocol.
The NDMP guide provides more information.
Introduction to DDS
DDS controls application requests for tape media and allows the NetWorker server
and all storage nodes to access and share all attached devices.
A system administrator can configure DDS by setting a sharing policy for devices that
are accessible from multiple storage nodes.
There are two terms that are central to the use of DDS are drive and device. Within
the context of DDS, these terms are defined as follows:
l Drive—The physical backup object, such as a tape drive, disk, or file.
l Device—The access path to the physical drive.
Note: NetWorker only supports DDS in a storage area network (SAN) Fibre
Channel environment and not in a direct-connect SCSI environment.
Benefits of DDS
Enabling DDS on a NetWorker system provides these benefits:
l Reduces storage costs—You can share a single tape drive among several storage
nodes. In fact, since NetWorker software uses the same open tape format for
UNIX, Windows, NetWare and Linux, you can share the same tape between
different platforms (assuming that respective save sets belong to the same pool).
l Reduces LAN traffic—You can configure clients as SAN storage nodes that can
send save sets over the SAN to shared drives.
l Provides fault tolerance—Within a SAN environment, you can configure hardware
to eliminate a single point of failure.
l Provides configuration over a greater distance—You can configure a system over
a greater distance than with SCSI connections.
In this figure:
l Storage nodes sn_1 and sn_2 are attached to the library.
l Each storage node, on its own, has access to drive_1 and drive_2.
l With DDS enabled, both storage nodes have access to both drives and can
recognize when a shared drive is in use.
This configuration requires two DDS licenses, one for each drive.
Note: Ensure that all applicable devices can be seen from each storage node by
running the inquire -l command locally on each storage node.
The settings that relate to Reserve/Release and Persistent Reserve are found in a
device’s Properties window, on the Advanced tab. They are visible only when
diagnostic mode is turned on.
The default setting for Reserve/Release is None. Once any other Reserve/Release
setting is selected, it works automatically, without further user intervention. The
Reserve/Release attribute is supported only on Common Device Interface (CDI)
platforms, so if the CDI attribute in a device’s Properties is set to Not Used, then
Reserve/Release settings are ignored.
For newer hardware, once a Reserve/Release setting (other than None) has been
selected, the appropriate Persistent Reserve commands are automatically issued
before a device is opened for reading or writing, and before the device is closed. With
older hardware, a SCSI-2 Reserve command is issued before opening the device, and a
SCSI-2 Release command is issued after the device is closed.
Reserve/Release has these possible settings:
l None (the default)
l Simple
l Persistent Reserve
l Persistent Reserve + APTPL (Activate Persist Through Power Loss)
The Persistent Reserve Key attribute has also been added. It is used with Persistent
Reservation calls.
Hardware ID attribute
The Hardware ID attribute tracks the drives that are shared between multiple hosts.
Device instances that share the same physical drive across multiple hosts have the
same hardware ID. The device autoconfiguration process automatically assigns the
Value Description
Enable All When selected, enables all devices with the same Hardware
ID.
Disable All When selected, disables all the devices with the same
Hardware ID.
Done This value is the default setting. After the server has enabled
or disabled all devices with the same Hardware ID, the
attribute value is reset to Done.
You cannot configure the Shared Devices attribute with the jbconfig program.
l To avoid accidentally filling an FTD, set the Volume Default Capacity attribute to
restrict the size of the device. For example, if a capacity of 100 MB is set, then the
device will be marked full when 100 MB is reached.
l Volume Default Capacity attribute must not be set to a value of more than 4 TB.
l If the Volume Default Capacity of a volume changes, the changes do not take
effect until the FTD is re-created, the directory contents are deleted, and the
volume is relabeled.
NOTICE If the FTD is used before the Volume Default Capacity attribute is set,
then the legacy data on that FTD must be staged or cloned to another device.
Otherwise, this data will be overwritten.
Stand-alone devices
A Device resource must be created for each stand-alone tape device on a storage
node. Stand-alone drives must be configured individually.
Storage nodes must have been created before devices can be configured to be used
by them. Storage nodes on page 98 provides information about storage nodes and
how to create them. Note that all scanning for devices is done at the storage node
level, and can be done across multiple storage nodes. Only devices that have serial
numbers can be autoconfigured. Use the jbconfig command to configure devices
that do not have serial numbers.
Note: Devices must be updated to the most recent firmware and drivers.
6. If the volume is recyclable, a message warns that the named volume is about to
be recycled, and asks whether to continue. Click Yes to re-label and recycle the
volume.
7. After a volume is labeled and mounted in a device, the volume is available to
receive data. Since the NetWorker label is internal and machine-readable, place
an adhesive label on each volume that matches that internal volume label.
Configuring a library to use volumes with barcodes on page 144 provides
information on using barcode labels.
Note: If you are in the process of re-labeling a mounted volume and you
choose not to overwrite the existing label, the volume is left in an
unmounted state. To use this volume, mount it again.
Labeling volumes
The NetWorker software applies a label template to create a unique internal label for
each volume. The label corresponds to a pool and identifies the pool for the volume
during backup and other operations.
Several preconfigured label templates are supplied with the NetWorker software. You
cannot delete these preconfigured label templates. Naming label templates on page 79
provides more information.
When you label a volume, the labeling process:
l Writes a label on the volume.
l Adds the volume label to the media database.
l Prepares tape media to have data written to it.
When you re-label tape, the data on the tape is effectively gone.
During data recovery, the server requests the volume that contains the required data,
identifying the required volume by the name with which it was labeled.
NOTICE A volume that has been set to manual recycle retains that setting,
even after the volume is re-labeled. You must explicitly reset the volume to
automatic recycle by right-clicking the volume in the Media window,
selecting Recycle, and then selecting the Auto option.
Maintenance commands
NetWorker device driver software provides maintenance commands, such as
lusbinfo and lusdebug, that you can use to diagnose problems on tape devices
and autochangers.
The UNIX man page and the NetWorker Command Reference Guide provides detailed
information about how to use these commands.
nsrjb -Hv
4. Inventory: the autochanger:
nsrjb -Iv
The UNIX man page and the NetWorker Command Reference Guide provides detailed
information about the nsrjb command.
To resolve the problem, use the nsrjb -H command to reset the autochanger.
Tapes get stuck in drive when labeling tapes on Linux Red Hat platform
When you label a tape in a DDS configuration on an RHEL NetWorker server, the tape
may become stuck in the drive and display the following error message:
unload failure-retrying 30 seconds
To resolve this issue, set the auto_lock setting attribute to “0” (Off) in
the /etc/stinit.def file for the following drive types:
l Sony AIT-2 and AIT-3
l IBM LTO Gen1
l HP LTO Gen1
l If inquire reports the serial number of the arm, follow the procedure at
Scanning for libraries and devices on page 142 to scan the library for
devices, then enable the library in NMC:
a. In the Administration window, click Devices.
b. Expand the Libraries folder, then right-click the library and select
Enabled/Disable.
l If inquire does not report the serial number or if the scan for devices
operation does not detect the control port change, use the nsradmin
command to change the control port:
a. Log in as root or as Windows administrator on the NetWorker host that
manages the control port.
b. At the command prompt, type nsradmin The nsradmin prompt
appears.
c. To disable the library, type the following commands:
where b.t.l is the bus.target.lun of the library’s robotic arm (as reported
by the inquire command).
f. When nsradmin prompts you to update the resource, type yes.
g. To re-enable the library, type:
To resolve this issue, changes the sleep attributes in the Autochanger resource.
1. Shut down NetWorker services.
2. Shut down and restart the autochanger that contains the TZ89 drives.
3. When the autochanger is back online, restart NetWorker services. NetWorker will
not try to unload the drive again.
4. Use NMC to edit the following autochanger sleep time attributes, and use the
following values:
l Eject Sleep: 18 secs
l Unload Sleep: 40 secs
l Load Sleep: 40 secs
Additional attributes in the Autochanger resource on page 197 provides
information about how to set the sleep attributes.
5. Try to unload the drive again. If the drive fails to unload, repeat this procedure and
increase the sleep times.
To avoid this message, do not enable the CDI attribute for these device types.
Solaris
The st.conf file contains a setting for each device type in use that enables or
disables the SCSI reserve/release feature. The Tape Configuration section of the st
man page provides more information. Use the most up-to-date st driver that is
available for the version of Solaris.
Edit the st.conf file only if one of the following conditions apply:
l The NetWorker configuration includes DDS.
l Solaris st does not support a tape drive that is configured on a Solaris host.
To determine if the Solaris st tape driver supports a tape drive, perform the following
steps:
1. Use the mt command to load a tape in the drive. For example, with the tape device
file 0cbn, the type: mt -f /dev/rmt/0cbn status
l If the output of the mt command includes the line SCSI tape drive or appears
similar to the following, the st tape driver uses generic settings, which do not
support the tape drive:
mt -f /dev/rmt/4cbn status
Vendor 'IBM ' Product 'ULT3580-TD2 ' tape drive:
sense key(0x6)= Unit Attention residual= 0
retries= 0 file no= 0 block no= 0
Tape operations may appear to work in NetWorker but you may run into
problems when you try to recover saved data.
l If the output of the mt command appears similar to the following, the st tape
driver recognizes the drive and uses the correct internal settings to manage
the drive:
mt -f /dev/rmt/0cbn status
HP Ultrium LTO tape drive:
sense key(0x0)= No Additional Sense residual= 0
retries= 0 file no= 0 block no= 0
In this configuration, you must only edit the st.conf file when you use the
drive in a DDS configuration.
AIX
To reset the reserve/release setting on an AIX operating system, use the SMIT
interface.
1. From the Devices menu, select Tapes.
2. Change the value for the RESERVE/RELEASE support attribute from No to Yes.
HP-UX
To reset the reserve/release setting on an HP-UX 11 operating system, perform the
following steps.
1. Change the st_ats_enable kernel variable to a value other than zero.
2. (Optional) Restart the computer to ensure that the operating system implements
the change.
Note: The reserve/release is a fixed setting in HP-UX 10.
When the mt command reports that the tape drive is online, you can use the
scanner command to scan the save set information into the media database
and client file index of the destination NetWorker server.
work list is composed of one or several work items. Work items include client
resources, virtual machines, save sets, or tags. You can chain multiple actions
together to occur sequentially or concurrently in a workflow. All chained actions use
the same work list.
When you configure an action, you define the days on which to perform the action, as
well as other settings specific to the action. For example, you can specify a destination
pool, a retention period, and a target storage node for the backup action, which can
differ from the subsequent action that clones the data.
When you create an action for a policy that is associated with the virtual machine
backup, you can select one of the following data protection action types:
l Backup — Performs a backup of virtual machines in vCenter to a Data Domain
system. You can only perform one VMware backup action per workflow. The
VMware backup action must occur before clone actions.
l Clone — Performs a clone of the VMware backup on a Data Domain system to any
clone device that NetWorker supports (including Data Domain system or tape
targets). You can specify multiple clone actions. Clone actions must occur after
the Backup action.
You can create multiple actions for a single workflow. However, each action applies to
a single workflow and policy.
The following figure provides a high level overview of the components that make up a
data protection policy in a datazone.
Figure 16 Data Protection Policy
Gold policy
The Gold policy provides an example of a data protection policy for an environment
that contains virtual machines and requires backup data redundancy.
Silver policy
The Silver policy provides an example of a data protection policy for an environment
that contains machines where file systems or applications are running and requires
backup data redundancy.
Bronze policy
The Bronze policy provides an example of a data protection policy for an environment
that contains machines where file systems or applications are running.
The following figure illustrates a policy with two different workflows. Workflow 1
performs a probe action, then a backup of the client resources in Client group 1, and
then a clone of the save sets from the backups. Workflow 2 performs a backup of the
client resources in Dynamic client group 1, and then a clone of the save sets from the
backup.
Creating a policy
Procedure
1. In the Administration window, click Protection.
2. In the expanded left pane, right-click Policies, and then select New.
The Create Policy dialog box appears.
3. On the General tab, in the Name field, type a name for the policy.
The maximum number of characters for the policy name is 64.
l Legal Characters: _ : - + = # , . % @
l Illegal Characters: /\*?[]()$!^;'"`~><&|{}
Note: After you create a policy, the Name attribute is read-only.
nsrlog -f policy_notifications.log
l On Linux, to send an email notification, type the following command:
where:
n -s subject—Includes a standard email header with the message and
specifies the subject text for that header. Without this option, the
smtpmail program assumes that the message contains a correctly
formatted email header and nothing is added.
n -h mailserver—Specifies the hostname of the mail server to use to
relay the SMTP email message.
7. To specify the Restricted Data Zone (RDZ) for the policy, select the Restricted
Data Zones tab, and then select the RDZ from the list.
8. Click OK.
nsrlog -f policy_notifications.log
l On Linux, to send an email notification, type the following command:
where:
n -s subject—Includes a standard email header with the message and
specifies the subject text for that header. Without this option, the
smtpmail program assumes that the message contains a correctly
formatted email header and nothing is added.
n -h mailserver—Specifies the hostname of the mail server to use to
relay the SMTP email message.
n recipient1@mailserver—Is the email address of the recipient of the
notification. Multiple email recipients are separated by a space.
8. In the Running section, perform the following steps to specify when and how
often the workflow runs:
a. To ensure that the actions that are contained in the workflow run when the
policy or workflow starts, in the Enabled box, leave the option selected. To
prevent the actions in the workflow from running when the policy or
workflow that contains the action starts, clear this option.
b. To start the workflow at the time that is specified in the Start time
attribute, on the days that are defined in the action resource, in the
AutoStart Enabled box, leave the option selected. To prevent the workflow
from starting at the time that is specified in the Start time attribute, clear
this option.
c. To specify the time to start the actions in the workflow, in the Start Time
attribute, use the spin boxes.
The default value is 9:00 PM.
d. To specify how frequently to run the actions that are defined in the
workflow over a 24-hour period, use the Interval attribute spin boxes. If you
are performing transaction log backup as part of application-consistent
protection, you must specify a value for this attribute in order for
incremental transaction log backup of SQL databases to occur.
The default Interval attribute value is 24 hours, or once a day. When you
select a value that is less than 24 hours, the Interval End attribute appears.
To specify the last start time in a defined interval period, use the spin boxes.
For example, if the Start Time is 7:00 PM, the Interval is 1 hour, and the
Interval End is 11:00 PM., then the workflow automatically starts every hour
beginning at 7:00 PM. and the last start time is 11:00 PM.
4. From the Group Type list, leave the default selection of Clients.
5. In the Comment field, type a description of the group.
6. From the Policy-Workflow list, select the workflow that you want to assign the
group to.
Note: You can also assign the group to a workflow when you create or edit a
workflow.
7. (Optional) To specify the Restricted Datazone (RDZ) for the group, on the
Restricted Datazones tab, select the RDZ from the list.
8. Click OK.
After you finish
Create Client resources. Assign clients to a protection group, by using the Client
Configuration wizard or the General tab on the Client Properties page.
4. From the Group Type list, select Dynamic Clients. For steps 5 to 8, follow the
instructions given in Creating a client group.
l To check connectivity on a specific day, click the Execute icon on the day.
l To skip a connectivity check on a specific day, click the Skip icon on the
day.
l To check connectivity every day, select Execute from the list, and then click
Make All.
The following table provides details about the icons.
14. In the Parallelism field, specify the maximum number of concurrent operations
for the action. This is applicable if multiple rollover is implemented at an action
level.
For Direct-NDMP backups, set the parallelism value to the number of available
NDMP drives.
If you set the parallelism attribute to a higher value, there will not be enough
drives to support all the queued backup save sets. Large save sets might fail
due to the inactivity timeout limit.
When NDMP groups back up simultaneously, divide the number of drives by the
number of groups. Use this value for each of the parallelism attributes.
Setting the parallelism value for the group overrides the parallelism value that is
defined for the NDMP clients.
15. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but
continue with subsequent actions in the workflow, select Abort action.
Note: The Abort action option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types.
l To abort the entire workflow if there is a failure with one of the jobs in the
action, select Abort workflow.
Note: If any of the actions fail in the workflow, the workflow status does
not appear as interrupted or cancelled. NetWorker reports the workflow
status as failed.
16. From the Soft Limit list, select the amount of time after the action starts to
stop the initiation of new activities. The default value of 0 (zero) indicates no
amount of time.
17. From the Hard Limit list, select the amount of time after the action starts to
begin terminating activities. The default value of 0 (zero) indicates no amount
of time.
18. (Optional) In Start Time specify the time to start the action.
Use the spin boxes to set the hour and minute values, and select one of the
following options from the drop-down list:
l Disabled—Do not enforce an action start time. The action will start at the
time defined by the workflow.
l Absolute—Start the action at the time specified by the values in the spin
boxes.
l Relative—Start the action after the period of time defined in the spin boxes
has elapsed after the start of the workflow.
19. (Optional) Configure overrides for the task that is scheduled on a specific day.
To specify the month, use the navigation buttons and the month list box. To
specify the year, use the spin boxes. You can set an override in the following
ways:
l Select the day in the calendar, which changes the action task for the
specific day.
l Use the action task list to select the task, and then perform one of the
following steps:
n To define an override that occurs on a specific day of the week, every
week, select Specified day, and then use the lists. Click Add Rules
based override.
n To define an override that occurs on the last day of the calendar month,
select Last day of the month. Click Add Rules based override.
Note:
n You can edit or add the rules in the Override field.

l Snapshot backup
6. If you create the action as part of the workflow configuration, the workflow
appears automatically in the Workflow box and the box is dimmed.
7. Specify the order of the action in relation to other actions in the workflow:
l If the action is part of a sequence of actions in a workflow path, in the
Previous box, select the action that should precede this action.
l If the action should run concurrently with an action, in the Previous box,
select the concurrent action, and then select the Concurrent checkbox.
8. Specify a weekly or monthly schedule for the action:
l To specify a schedule for each day of the week, select Weekly by day.
l To specify a schedule for each day of the month, select Monthly by day.
9. Specify the days to probe the client:
l To perform a probe action on a specific day, click the Execute icon on the
day.
l To skip a probe action, click the Skip icon on the day.
l To perform a probe action every day, select Execute from the list, and then
click Make All.
The following table provides details on the icons.
14. In the Retry Delay field, specify a delay in seconds to wait before retrying a
failed probe or backup action. When the Retry Delay value is 0, NetWorker
retries the failed probe or backup action immediately.
Note: The Retry Delay option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types. When you specify a
value for this option in other actions, NetWorker ignores the values.
15. In the Inactivity Timeout field, specify the maximum number of minutes that a
job run by an action can try to respond to the server.
If the job does not respond within the specified time, the server considers the
job a failure and NetWorker retries the job immediately to ensures that no time
is lost due to failures.
Increase the timeout value if a backup consistently stops due to inactivity.
Inactivity might occur for backups of large save sets, backups of save sets with
large sparse files, and incremental backups of many small static files.
Note: The Inactivity Timeout option applies to probe actions, and the
backup actions for the Traditional and Snapshot action types. If you specify
a value for this option in other actions, NetWorker ignores the value.
16. In the Parallelism field, specify the maximum number of concurrent operations
for the action. This is applicable if multiple rollover is implemented at an action
level.
For Direct-NDMP backups, set the parallelism value to the number of available
NDMP drives.
If you set the parallelism attribute to a higher value, there will not be enough
drives to support all the queued backup save sets. Large save sets might fail
due to the inactivity timeout limit.
When NDMP groups back up simultaneously, divide the number of drives by the
number of groups. Use this value for each of the parallelism attributes.
Setting the parallelism value for the group overrides the parallelism value that is
defined for the NDMP clients.
17. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but
continue with subsequent actions in the workflow, select Abort action.
Note: The Abort action option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types.
l To abort the entire workflow if there is a failure with one of the jobs in the
action, select Abort workflow.
Note: If any of the actions fail in the workflow, the workflow status does
not appear as interrupted or cancelled. NetWorker reports the workflow
status as failed.
18. Do not change the default selections for the Notification group box. NetWorker
does not support notifications for probe actions and ignores and specified
values.
19. From the Soft Limit list, select the amount of time after the action starts to
stop the initiation of new activities. The default value of 0 (zero) indicates no
amount of time.
20. From the Hard Limit list, select the amount of time after the action starts to
begin terminating activities. The default value of 0 (zero) indicates no amount
of time.
21. (Optional) In Start Time specify the time to start the action.
Use the spin boxes to set the hour and minute values, and select one of the
following options from the drop-down list:
l Disabled—Do not enforce an action start time. The action will start at the
time defined by the workflow.
l Absolute—Start the action at the time specified by the values in the spin
boxes.
l Relative—Start the action after the period of time defined in the spin boxes
has elapsed after the start of the workflow.
22. (Optional) Configure overrides for the task that is scheduled on a specific day.
To specify the month, use the navigation buttons and the month list box. To
specify the year, use the spin boxes. You can set an override in the following
ways:
l Select the day in the calendar, which changes the action task for the
specific day.
l Use the action task list to select the task, and then perform one of the
following steps:
n To define an override that occurs on a specific day of the week, every
week, select Specified day, and then use the lists. Click Add Rules
based override.
n To define an override that occurs on the last day of the calendar month,
select Last day of the month. Click Add Rules based override.
Note:
n You can edit or add the rules in the Override field.
n To remove an override, delete the entry from the Override field.
l If the action is the first action in the workflow, select Create a new action.
l If the workflow has other actions, right-click an empty area of the Actions
pane, and then select New.
The Policy Action wizard opens on the Specify the Action Information page.
2. In the Name field, type the name of the action.
The maximum number of characters for the action name is 64.
l Legal Characters: _ : - + = # , . % @
l Illegal Characters: /\*?[]()$!^;'"`~><&|{}
8. If you create the action as part of the workflow configuration, the workflow
appears automatically in the Workflow box and the box is dimmed.
9. Specify the order of the action in relation to other actions in the workflow:
l If the action is part of a sequence of actions in a workflow path, in the
Previous box, select the action that should precede this action.
l If the action should run concurrently with an action, in the Previous box,
select the concurrent action, and then select the Concurrent checkbox.
10. Specify a weekly or monthly schedule for the action:
l To specify a schedule for each day of the week, select Weekly by day.
l To specify a schedule for each day of the month, select Monthly by day.
11. To specify the backup level to perform, click the icon on each day.
The following table provides details about the backup level that each icon
represents.
To perform the same type of backup on each day, select the backup type from
the list and click Make All.
NetWorker does not support the use of synthetic full backup levels for NDMP
data.
Celerra, Isilon, VNX, Unity, and NetApp filers with NDMP version 4 or later
support token-based backups (TBB) to perform NDMP full and incremental
backups. NetWorker supports the same number of incremental levels that the
NAS vendor supports. Celerra, Isilon, and NetApp documentation provide the
maximum number of incremental levels that the TBB incremental backup can
support.
When you configure TBB after you update the NetWorker server from 7.6 SP1
or earlier, the first incremental backup does not occur until after one complete
full backup.
Filers that do not support TBB, do not support incremental backups. If you
select the level Incr, the NetWorker server performs a full backup.
Verify that the NAS storage vendor supports NDMP incremental backups
before you use this feature.
When you define the retention policy an NDMP client, consider the amount of
disk space that is required for the client file index. NDMP clients with several
thousands of small files have significantly larger client file indexes on the
NetWorker server than a non-NDMP client. A long retention policy for an
NDMP client increases disk space requirements on the file system that contains
the client file indexes.
16. From the Client Override Behavior box, specify how NetWorker uses certain
client configuration attributes that perform the same function as attributes in
the Action resource:
l Client Can Override—The values in the Client resource for Schedule, Pool,
Retention policy, and the Storage Node attributes take precedence over
the values that are defined in the equivalent Action resource attributes.
Note: If the NetWorker policy action schedule is set to the Skip backup
level, the Client can Override option is not honored. For NetWorker to
consider the Client can Override option, change the action schedule to
a different level.
l Client Can Not Override—The values in the Action resource for the
Schedule, Destination Pool, Destination Storage Node, and the
Retention attributes take precedence over the values that are defined in the
equivalent Client resource attributes.
l Legacy Backup Rules—This value only appears in actions that are created
by the migration process. The updating process sets the Client Override
Behavior for the migrated backup actions to Legacy Backup Rules.
19. In the Retry Delay field, specify a delay in seconds to wait before retrying a
failed probe or backup action. When the Retry Delay value is 0, NetWorker
retries the failed probe or backup action immediately.
Note: The Retry Delay option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types. When you specify a
value for this option in other actions, NetWorker ignores the values.
20. In the Inactivity Timeout field, specify the maximum number of minutes that a
job run by an action can try to respond to the server.
If the job does not respond within the specified time, the server considers the
job a failure and NetWorker retries the job immediately to ensures that no time
is lost due to failures.
Increase the timeout value if a backup consistently stops due to inactivity.
Inactivity might occur for backups of large save sets, backups of save sets with
large sparse files, and incremental backups of many small static files.
Note: The Inactivity Timeout option applies to probe actions, and the
backup actions for the Traditional and Snapshot action types. If you specify
a value for this option in other actions, NetWorker ignores the value.
21. In the Parallelism field, specify the maximum number of concurrent operations
for the action. This is applicable if multiple rollover is implemented at an action
level.
For Direct-NDMP backups, set the parallelism value to the number of available
NDMP drives.
If you set the parallelism attribute to a higher value, there will not be enough
drives to support all the queued backup save sets. Large save sets might fail
due to the inactivity timeout limit.
When NDMP groups back up simultaneously, divide the number of drives by the
number of groups. Use this value for each of the parallelism attributes.
Setting the parallelism value for the group overrides the parallelism value that is
defined for the NDMP clients.
22. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but
continue with subsequent actions in the workflow, select Abort action.
Note: The Abort action option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types.
l To abort the entire workflow if there is a failure with one of the jobs in the
action, select Abort workflow.
Note: If any of the actions fail in the workflow, the workflow status does
not appear as interrupted or cancelled. NetWorker reports the workflow
status as failed.
23. From the Soft Limit list, select the amount of time after the action starts to
stop the initiation of new activities. The default value of 0 (zero) indicates no
amount of time.
24. From the Hard Limit list, select the amount of time after the action starts to
begin terminating activities. The default value of 0 (zero) indicates no amount
of time.
25. (Optional) In Start Time specify the time to start the action.
Use the spin boxes to set the hour and minute values, and select one of the
following options from the drop-down list:
l Disabled—Do not enforce an action start time. The action will start at the
time defined by the workflow.
l Absolute—Start the action at the time specified by the values in the spin
boxes.
l Relative—Start the action after the period of time defined in the spin boxes
has elapsed after the start of the workflow.
26. (Optional) Configure overrides for the task that is scheduled on a specific day.
To specify the month, use the navigation buttons and the month list box. To
specify the year, use the spin boxes. You can set an override in the following
ways:
l Select the day in the calendar, which changes the action task for the
specific day.
l Use the action task list to select the task, and then perform one of the
following steps:
n To define an override that occurs on a specific day of the week, every
week, select Specified day, and then use the lists. Click Add Rules
based override.
n To define an override that occurs on the last day of the calendar month,
select Last day of the month. Click Add Rules based override.
Note:
n You can edit or add the rules in the Override field.
n To remove an override, delete the entry from the Override field.
27. From the Send Notifications list box, select whether to send notifications for
the action:
l To use the notification configuration that is defined in the Policy resource to
send the notification, select Set at policy level.
l To send a notification on completion of the action, select On Completion.
l To send a notification only if the action fails to complete, select On Failure.
28. In the Send notification attribute, when you select the On Completion option
or On failure option, the Command box appears. Use this box to configure how
NetWorker sends the notifications. You can use the nsrlog command to send
the notifications to a log file or you can send an email notification.
The default notification action is to send the information to the
policy_notifications.log file. By default, the
policy_notifications.log file is located in the /nsr/logs directory on
Linux and in the C:\Program Files\EMC NetWorker\nsr\logs folder on
Windows.
Use the default mailer program on Linux to send email messages or the
smtpmail application on Windows:
l To send notifications to a file, type the following command, where
policy_notifications.log is the name of the file:
nsrlog -f policy_notifications.log
where:
n -s subject—Includes a standard email header with the message and
specifies the subject text for that header. Without this option, the
smtpmail program assumes that the message contains a correctly
formatted email header and nothing is added.
n -h mailserver—Specifies the hostname of the mail server to use to
relay the SMTP email message.
n recipient1@mailserver—Is the email address of the recipient of the
notification. Multiple email recipients are separated by a space.
from running when the policy or workflow that contains the action is started,
clear this option.
Note: When you clear the Enabled option, actions that occurs after a
disabled action do not start, even if the subsequent options are enabled.
After the retention period expires, the save sets are marked as recyclable
during an expiration server maintenance task.
12. In the Filters section, define the criteria that NetWorker uses to create the list
of eligible save sets to clone. The eligible save sets must match the
requirements that are defined in each filter. NetWorker provides the following
filter options:
a. Time filter—In the Time section, specify the time range in which NetWorker
searches for eligible save sets to clone in the media database. Use the spin
boxes to specify the start time and the end time. The Time filter list includes
the following options to define how NetWorker determines save set
eligibility, based on the time criteria:
l Do Not Filter—NetWorker inspects the save sets in the media database
to create a clone save set list that meets the time filter criteria.
l Accept—The clone save set list includes save sets that are saved within
the time range and meet all the other defined filter criteria.
l Reject—The clone save set list does not include save sets that are saved
within the time range and meet all the other defined filter criteria.
b. Save Set filter—In the Save Set section, specify whether to include or
exclude ProtectPoint and Snapshot save sets, when NetWorker searches for
eligible save sets to clone in the media database. The Save Set filter list
includes to the following options define how NetWorker determines save set
eligibility, based on the save set filter criteria:
l Do Not Filter—NetWorker inspects the save sets in the media database
to create a clone save set list that meets the save set filter criteria.
l Accept—The clone save set list includes eligible ProtectPoint save sets
or Snapshot save sets, when you also enable the ProtectPoint checkbox
or Snapshot checkbox.
l Reject—The clone save set list does not include eligible ProtectPoint
save sets and Snapshot save sets when you also enable the ProtectPoint
checkbox or Snapshot checkbox.
Note: For NAS device, only Snapshot save set is applicable.
15. In the Parallelism field, specify the maximum number of concurrent operations
for the action. This is applicable if multiple rollover is implemented at an action
level.
For Direct-NDMP backups, set the parallelism value to the number of available
NDMP drives.
If you set the parallelism attribute to a higher value, there will not be enough
drives to support all the queued backup save sets. Large save sets might fail
due to the inactivity timeout limit.
When NDMP groups back up simultaneously, divide the number of drives by the
number of groups. Use this value for each of the parallelism attributes.
Setting the parallelism value for the group overrides the parallelism value that is
defined for the NDMP clients.
16. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but
continue with subsequent actions in the workflow, select Abort action.

Protection groups for NetWorker and NMC server backup and maintenance
When you install or upgrade the NetWorker server, the installation or upgrade process
creates a default protection group for the NetWorker server workflows in the Server
Protection policy.
Server Protection group
The Server Protection group is a default protection group to back up the NetWorker
server bootstrap and client file indexes. The Server Protection group is assigned to
the Server backup workflow in the default Server Protection policy. The Server
backup workflow performs a bootstrap backup, which includes the NetWorker server
resource files, media database, NetWorker Authentication Service database, and client
indexes for disaster recovery. The group is a dynamic client group that automatically
generates a list of Client resources for the NetWorker server.
NMC server group
The NMC server group is a default protection group to back up the NMC database,
which the Console Configuration wizard prompts you to create the first time you log
in to the NMC server. The group is a client group that contains the Client resource for
the NMC server and is created during the initial login and configuration of NMC
server. The NMC server group is assigned to the NMC server backup workflow in the
default Server Protection policy.
Note: If you create custom groups for server backup and maintenance, ensure
that they include both the NetWorker server and the NMC server.
Actions in the server database backup and NMC server backup workflows
Workflows enable you to chain together multiple actions and run them sequentially or
concurrently.
The following supported actions can follow the lead action and other actions in a
workflow.
Workflow path from a server database backup action
The Clone action is the only supported action after a server database backup action.
You cannot insert an action before a server database backup action.
The oval icon specifies the group to which the workflow applies. The rounded
rectangle icons identify actions. The parallelogram icons identify the destination pool
for the action.
You can work directly in the visual representation of a workflow to perform the
following tasks:
l You can adjust the display of the visual representation by right-clicking and
selecting one of the following options:
n Zoom In—Increase the size of the visual representation.
n Zoom Out—Decrease the size of the visual representation.
n Zoom Area—Limit the display to a single section of the visual representation.
n Fit Content—Fit the visual representation to the window area.
n Reset—Reset the visual representation to the default settings.
n Overview—View a separate dialog box with a high-level view of the visual
representation and a legend of the icons.
l You can view and edit the properties for the group, action, or destination pool by
right-clicking the icon for the item, and then select Properties.
l You can create a group, action, or destination pool by right-clicking the icon for
the item, and then select New.
Debug 9
Note: The Backup Data Management chapter describes how you can clone save
sets manually by using the nsrclone command.
2. Create a policy. When you create a policy, you specify the name and notification
settings for the policy.
3. Within the policy, create a workflow. When you create a workflow, you specify
the name of the workflow, the schedule for running the workflow, notification
settings for the workflow, and the protection group to which the workflow
applies.
4. Create one or more clone actions for the workflow.
Use a save set group or a query group to specify a list of save sets if cloning occurs as
the head action in a cloning workflow:
l Save set group—Use a save set group in clone-only workflows where you want to
clone a specific list of save sets. Save set groups are similar to the manual clone
operations in NetWorker 8.2.x and earlier.
l Query group—Use a query group in clone-only workflows where you want to clone
save sets on an ongoing basis, based on the save set criteria that you define.
Query groups are similar to the scheduled clone operations in NetWorker 8.2.x and
earlier.
Note: To clone save sets in a backup workflow, use basic client group or a dynamic
client group. Strategies for traditional backups provides detailed information about
how to create clone actions in a traditional backup workflow.
Create multiple protection groups to perform cloning in different ways as part of
separate workflows, or to perform cloning for different save sets on different
schedules. For example:
l Create a basic client group for a workflow that performs a traditional backup of
the a client file system followed by cloning of the save sets that result from the
backup. In this case, concurrent cloning can be enabled.
l Create a query group that identifies full save sets in the last two days to clone.
Creating a save set group
A save set group defines a static list of save sets for cloning or for snapshot index
generation.

AutoStart Enabled box, leave the option selected. To prevent the workflow
from starting at the time that is specified in the Start time attribute, clear
this option.
c. To specify the time to start the actions in the workflow, in the Start Time
attribute, use the spin boxes.
The default value is 9:00 PM.
d. To specify how frequently to run the actions that are defined in the
workflow over a 24-hour period, use the Interval attribute spin boxes. If you
are performing transaction log backup as part of application-consistent
protection, you must specify a value for this attribute in order for
incremental transaction log backup of SQL databases to occur.
The default Interval attribute value is 24 hours, or once a day. When you
select a value that is less than 24 hours, the Interval End attribute appears.
To specify the last start time in a defined interval period, use the spin boxes.
l To specify a schedule for each day of the week, select Weekly by day.
l To specify a schedule for each day of the month, select Monthly by day.
9. Specify the days to perform cloning:
l To clone on a specific day, click the Execute icon on the day.
l To skip a clone on a specific day, click the Skip icon on the day.
l To check connectivity every day, select Execute from the list, and then click
Make All.
The following table provides details on the icons.
l Reject—The clone save set list does not include save sets that are saved
within the time range and meet all the other defined filter criteria.
b. Save Set filter—In the Save Set section, specify whether to include or
exclude ProtectPoint and Snapshot save sets, when NetWorker searches for
eligible save sets to clone in the media database. The Save Set filter list
includes to the following options define how NetWorker determines save set
eligibility, based on the save set filter criteria:
l Do Not Filter—NetWorker inspects the save sets in the media database
to create a clone save set list that meets the save set filter criteria.
l Accept—The clone save set list includes eligible ProtectPoint save sets
or Snapshot save sets, when you also enable the ProtectPoint checkbox
or Snapshot checkbox.
l Reject—The clone save set list does not include eligible ProtectPoint
save sets and Snapshot save sets when you also enable the ProtectPoint
checkbox or Snapshot checkbox.
Note: For NAS device, only Snapshot save set is applicable.
Note: Although the Retries, Retry Delay, or the Inactivity Timeout options
appear, the clone action does not support these options and ignores the
values.
15. In the Parallelism field, specify the maximum number of concurrent operations
for the action. This is applicable if multiple rollover is implemented at an action
level.
For Direct-NDMP backups, set the parallelism value to the number of available
NDMP drives.
If you set the parallelism attribute to a higher value, there will not be enough
drives to support all the queued backup save sets. Large save sets might fail
due to the inactivity timeout limit.
When NDMP groups back up simultaneously, divide the number of drives by the
number of groups. Use this value for each of the parallelism attributes.
Setting the parallelism value for the group overrides the parallelism value that is
defined for the NDMP clients.
16. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but
continue with subsequent actions in the workflow, select Abort action.
Note: The Abort action option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types.
l To abort the entire workflow if there is a failure with one of the jobs in the
action, select Abort workflow.
Note: If any of the actions fail in the workflow, the workflow status does
not appear as interrupted or cancelled. NetWorker reports the workflow
status as failed.
17. From the Send Notifications list box, select whether to send notifications for
the action:
l To use the notification configuration that is defined in the Policy resource to
send the notification, select Set at policy level.
l To send a notification on completion of the action, select On Completion.
l To send a notification only if the action fails to complete, select On Failure.
18. In the Send notification attribute, when you select the On Completion option
or On failure option, the Command box appears. Use this box to configure how
NetWorker sends the notifications. You can use the nsrlog command to send
the notifications to a log file or you can send an email notification.
The default notification action is to send the information to the
policy_notifications.log file. By default, the
policy_notifications.log file is located in the /nsr/logs directory on
Linux and in the C:\Program Files\EMC NetWorker\nsr\logs folder on
Windows.
Use the default mailer program on Linux to send email messages or the
smtpmail application on Windows:
l To send notifications to a file, type the following command, where
policy_notifications.log is the name of the file:
nsrlog -f policy_notifications.log
l On Linux, to send an email notification, type the following command:
where:
n -s subject—Includes a standard email header with the message and
specifies the subject text for that header. Without this option, the
smtpmail program assumes that the message contains a correctly
formatted email header and nothing is added.
n -h mailserver—Specifies the hostname of the mail server to use to
relay the SMTP email message.
n recipient1@mailserver—Is the email address of the recipient of the
notification. Multiple email recipients are separated by a space.
19. From the Soft Limit list, select the amount of time after the action starts to
stop the initiation of new activities. The default value of 0 (zero) indicates no
amount of time.
20. From the Hard Limit list, select the amount of time after the action starts to
begin terminating activities. The default value of 0 (zero) indicates no amount
of time.
21. (Optional) In the Start Time option, specify the time to start the action.
Use the spin boxes to set the hour and minute values, and select one of the
following options from the list box:
l Disabled—Do not enforce an action start time. The action will start at the
time defined by the workflow.
l Absolute—Start the action at the time specified by the values in the spin
boxes.
l Relative—Start the action after the period of time defined in the spin boxes
has elapsed after the start of the workflow.
22. (Optional) Configure overrides for the task that is scheduled on a specific day.
To specify the month, use the navigation buttons and the month list box. To
specify the year, use the spin boxes. You can set an override in the following
ways:
l Select the day in the calendar, which changes the action task for the
specific day.
l Use the action task list to select the task, and then perform one of the
following steps:
n To define an override that occurs on a specific day of the week, every
week, select Specified day, and then use the lists. Click Add Rules
based override.
n To define an override that occurs on the last day of the calendar month,
select Last day of the month. Click Add Rules based override.
Note:
n You can edit or add the rules in the Override field.
n To remove an override, delete the entry from the Override field.
The oval icon specifies the group to which the workflow applies. The rounded
rectangle icons identify actions. The parallelogram icons identify the destination pool
for the action.

right-clicking the icon for the item, and then select Properties.
l You can create a group, action, or destination pool by right-clicking the icon for
the item, and then select New.
Note: The amount of data and length of time that is required to complete the
backup can impact the ability to clone data when the backup and clone workflows
are in the same policy. For example, if the clone action starts before the backup
action completes, there might not be any data yet to clone, or in other cases, only
the save sets that completed at the start time of the workflow is taken into
account. In both cases, NetWorker marks the Clone Workflow as successful, but
there is no guarantee that all the data from the backup workflow was cloned.
2. In the expanded left pane, expand Policies, and then select the existing policy.
3. In the right pane, right-click in the workflow section and select New, and select

8. In the Running section, perform the following steps to specify when and how
often the workflow runs:
a. To ensure that the actions that are contained in the workflow run when the
policy or workflow starts, in the Enabled box, leave the option selected. To
prevent the actions in the workflow from running when the policy or
workflow that contains the action starts, clear this option.
b. To start the workflow at the time that is specified in the Start time
attribute, on the days that are defined in the action resource, in the
AutoStart Enabled box, leave the option selected. To prevent the workflow
from starting at the time that is specified in the Start time attribute, clear
this option.
c. To specify the time to start the actions in the workflow, in the Start Time
attribute, use the spin boxes.
The default value is 9:00 PM.
d. To specify how frequently to run the actions that are defined in the
workflow over a 24-hour period, use the Interval attribute spin boxes. If you
are performing transaction log backup as part of application-consistent
protection, you must specify a value for this attribute in order for
incremental transaction log backup of SQL databases to occur.
The default Interval attribute value is 24 hours, or once a day. When you
select a value that is less than 24 hours, the Interval End attribute appears.
To specify the last start time in a defined interval period, use the spin boxes.
9. In the Groups group box, specify the protection group to which the workflow
applies.
To use a group, select a protection group from the Groups list. To create a
protection group, click the + button that is located to the right of the Groups

save sets.
After the retention period expires, the save sets are marked as recyclable
during an expiration server maintenance task.
20. In the Filters section, define the criteria that NetWorker uses to create the list
of eligible save sets to clone. The eligible save sets must match the
requirements that are defined in each filter. NetWorker provides the following
filter options:
a. Time filter—In the Time section, specify the time range in which NetWorker
searches for eligible save sets to clone in the media database. Use the spin
boxes to specify the start time and the end time. The Time filter list includes
the following options to define how NetWorker determines save set
eligibility, based on the time criteria:
l Do Not Filter—NetWorker inspects the save sets in the media database
to create a clone save set list that meets the time filter criteria.
l Accept—The clone save set list includes save sets that are saved within
the time range and meet all the other defined filter criteria.
l Reject—The clone save set list does not include save sets that are saved
within the time range and meet all the other defined filter criteria.
b. Save Set filter—In the Save Set section, specify whether to include or
exclude ProtectPoint and Snapshot save sets, when NetWorker searches for
eligible save sets to clone in the media database. The Save Set filter list

how NetWorker determines save set eligibility, based on the level filter
criteria:
l Do Not Filter—NetWorker inspects the save sets regardless of the level
in the media database, to create a clone save set list that meets all the
level filter criteria.
l Accept—The clone save set list includes eligible save sets with the
selected backup levels.
l Reject—The clone save set list does not include eligible save sets with
the selected backup levels.
Note: For NAS device, only full backup level is applicable.
23. In the Parallelism field, specify the maximum number of concurrent operations
for the action. This is applicable if multiple rollover is implemented at an action
level.
For Direct-NDMP backups, set the parallelism value to the number of available
NDMP drives.
If you set the parallelism attribute to a higher value, there will not be enough
drives to support all the queued backup save sets. Large save sets might fail
due to the inactivity timeout limit.
When NDMP groups back up simultaneously, divide the number of drives by the
number of groups. Use this value for each of the parallelism attributes.
Setting the parallelism value for the group overrides the parallelism value that is
defined for the NDMP clients.
24. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but

Policy Notifications
You can define how a Data Protection Policy sends notifications in the Policy,
Workflow, and Action resources.
The following table summarizes how the notification settings in each resource work
together.
In the Policy resource, the following notification choices are available:
l Never —Select this option when you do not want to send any notifications.
l On Completion—Select this option when you want to send a notification on
completion of the workflows and actions in the policy.
l On Failure—Select this option when you want to send a notification only if one or
more of the workflows in the policy fail.
When you configure a notification at the policy level, NetWorker applies the
notification to all workflows and actions in the policy that are not configured to send
out notifications.
In the Workflow resource, the following notification choices are available:
l To use the notification configuration that is defined in the policy resource to send
the notification, select Set a policy level.
l To send a workflow notification on completion of all the actions in the workflow,
select On Completion.
l To send a workflow notification only if an action fails to complete, select On
Failure.
When you configure a notification at the workflow level, the setting overrides what
you defined at the policy level.
In the Action resource, the following notification choices are available:
l To use the notification configuration that is defined in the policy resource to send
the notification, select Set a policy level.
l To send a notification on completion of the action, select On Completion.
l To send a notification only if the action fails to complete, select On Failure.
When you configure a notification at the action level, the setting overrides what you
defined at the policy level. If you configured the Workflow resource to send out
notifications, you will receive workflow notifications in addition to action notifications.
Icon Status
Never run
Running
Succeeded
Failed
Probing
When you sort the items on the Policy/Actions pane by using the Status column,
NetWorker sorts the items in alphabetical order that is based on the label of the icon.
Consider the following when a policy/action is in a probing state:
l A message is sent when the group starts and finishes the probe operation.
l The results of the probe operation (run backup/do not run backup) are also
logged.
l Probes do not affect the final status of the group, and the group status does not
indicate the results of the probe.
l If probing indicates that a backup should not run, then the group status reverts to
its state before the group running.
l Check the results of the probe in the Log window to ensure that the probe
indicates that the backup can be taken.
Actions pane
To view a list of all actions, click the Actions tab at the bottom of the Policies pane.
The Policies pane becomes the Actions pane.
The Actions pane provides the following information for each action:
l Overall status
Note: The Actions pane displays the same status icons as the Policies pane.
l Name
l Assigned policy
l Assigned workflow
l Type
l Date and time of the most recent run
l Duration of the most recent run
l Percent complete, for actions that are in progress
l Next scheduled runtime
Right-click an action in the Actions pane, and select Show Details to view details on
currently running, completed, and failed activities for the action.
Monitoring cloning
You can view the status of scheduled clone jobs in the Monitoring window. Status
information includes the last start time of the policy, workflow, or clone action, the
duration of the action, the size of the save set, and the target device, pool, and
volume.
To determine whether a save set on a volume has been cloned, or is itself a clone,
check the search for the save set by using the Query Save Set tab when you select
Save Sets in the Media window.
l Policy_name—is the name of the Policy resource. One folder per policy.
l Workflow_name—is the name of the workflow directory. One folder per action
sequence.
l Action_name—is the name of the action log file within the workflow.
Workflow log files
The policy subdirectory contains raw log files for each workflow and one subdirectory
for each action.
The location and format of the log file on Linux is:
/nsr/logs/policy/policy_name/workflow_name_jobid.raw
where name_jobid is the name of the workflow and the job id of the workflow. Job id is
a value that uniquely identifies a workflow job record in the jobdb.
For example, the log file for a workflow that is called server backup, with a job id of
0010072 appears as follows:
/nsr/logs/policy/server protection/workflow_server
backup_0010072.raw
Use the job id to perform queries of the jobdb with the jobquery command. A
workflow log file can be unrendered or rendered. An unrendered log file has the file
name extension .raw. A rendered log file's extension is .log. Unrendered log files
contain internationalized messages that can be rendered into the local language. The
content of rendered log files has been localized to a single country's language.
View log files provides more information about viewing rendered and unrendered log
files.
Action log files
NetWorker creates a workflow directory for each workflow within the policy directory.
The workflow directory contains log files for each action that is assigned to the
workflow.
The location of the workflow directory on Linux is:
/nsr/logs/policy/policy_name/workflow_name
where:
l policy_name—is the name of the policy that contains the workflow.
l workflow_name—is the name of the workflow.
The workflow directory contains log files for each action that is assigned to the
workflow. The file name appears in the following format:
action_name_job_id.raw
where:
l action_name—is the name of the action.
l job_id—is the job id of the action in the jobdb.
For example, the server backup workflow has three actions: Backup, Clone, and Clone
more. There are three log files in /nsr/logs/policy/server protection/
server backup directory with the following names:
Backup_ 1408063.raw
Clone_1408080.raw
Clone more_1408200.raw
3. Click Yes.
Protection period
You can use protection period to retain the last valid copy of a saveset for a specified
period of time even after it expires and the protection period is more than the
retention policy. This is a nsr data protection attribute and disabled by default.
Protection period is disabled by default. In order to enable this feature, you can check
the enable check box in the policy configuration tab.
Note: The protection period applies to scheduled backup save sets only, and it
does not apply to manual backup save sets. Some NetWorker module backups
might appear to be scheduled backups that are initiated by a policy backup action
but they are manual backups because they are initiated or converted by a
database or application. The NetWorker Module for Databases and Applications
Administration Guide and the NetWorker Module for SAP Administration Guide
provides more details.
Policies
Policies enable you to manage all data protection tasks and the data protection
lifecycle from a central location.
A policy contains one or more workflows, which define the actions that should be
performed, the order for the actions to occur, and the group of Client resources or
save sets on which to perform the actions.
Actions include backups, cloning, client/server connectivity checks, and NetWorker
server maintenance activities.
Editing a policy
You can edit the description, notification setting, and RDZ for a policy.
About this task

information about the workflows and actions within the policy expire in the
jobs database. The default job expiration time is 72 hours. Modifying the
retention period for jobs in the jobs database describes how to change the
default job expiration time.
Workflows
Workflows define a list of actions to perform sequentially or concurrently, a schedule
window during which the workflow can run, and the protection group to which the
workflow applies.
A workflow can be as simple as a single action that applies to a finite list of Client
resources, or it can be a complex chain of actions that apply to a dynamically changing
list of resources, with some actions occurring sequentially and others occurring
concurrently.
You can also define notification settings for a workflow.
After you create actions for a workflow, in the Administration interface, you can see a
map provides a visual representation of the actions on the right side of the Protection
window.
The oval icon specifies the group to which the workflow applies. The rounded
rectangle icons identify actions. The parallelogram icons identify the destination pool
for the action.
You can work directly in the visual representation of a workflow to perform the
following tasks:
l You can adjust the display of the visual representation by right-clicking and

a group, you only see the action types that are allowed in the action
sequence.
7. Click OK.
Deleting a workflow
When you delete a workflow, the deletion process also deletes all actions for the
workflow.
About this task
The group that is assigned to the workflow is not deleted, however. The workflow
assignment for the group is removed from the group properties. You can assign the
group to a different workflow or delete the group.

2. In the expanded left pane, select Policies.
3. Select the policy for the workflow.
4. In the right pane of the window, select the Workflows tab.
Protection groups
Protection groups enable you to define a set of Client resources or save sets.
Note: When you specify multiple tag values, the query uses an OR
operation to match the tags. For example, if you specify Sales and
Support tag values, then the query builds a list of clients that contain
the tag Sales or Support.
l To modify the clients in a Client group, from the Clients table, perform one
of the following actions in the Selected Clients column:
n To add a Client resource to the group, select the checkbox beside the
name of the Client resource.
n To remove Client resources from the group, clear the checkbox next to
the name of the Client resource.
5. Click OK.
Actions
Actions are the key resources in a workflow for a data protection policy. An action is a
task that occurs on a work list. A work list is a list of pending work items, such a group
of Client resources or save sets.
You can chain multiple actions together to occur sequentially or concurrently in a
workflow.
Creating an action
The Policy Action wizard walks you through the steps to create an action. You can
create an action either when you are creating or editing a workflow, or as a separate
process from the workflow configuration.
Before you begin

Querying NSR protection policy workflow and NSR protection policy action
resources without specifying RAP resource types
NSR Protection Policy Workflow and NSR Protection Policy Action are pseudo RAP
resources and encapsulated under NSR Protection Policy RAP resource. Querying
these pseudo RAP resources in nsradmin requires resource type. The nsradmin
command displays the following warning message for these pseudo resources, if
queried without resource type:
All other RAP resources including NSR Protection Policy resource can be queried
without specifying RAP resource Types.
The UNIX man pages and the NetWorker Command Reference Guide provide detailed
information about how to use the nsrpolicy command.

the notifications. You can use the nsrlog command to send the notifications
to a log file.
The default notification action is to send the information to the
policy_notifications.log file. By default, the Protecting virtual
machines policy_notifications.log file is located in the /nsr/logs
directory on Linux and in the C:\Program Files\EMC NetWorker\nsr
\logs folder on Windows.
Use the default mailer program on Linux to send email messages or the
smtpmail application on Windows:
l To send notifications to a file, type the following command, where
policy_notifications.log is the name of the file:
nsrlog -f policy_notifications.log
l On Linux, to send an email notification, type the following command:
mail -s subject recipient
l For NetWorker Virtual Edition (NVE), to send an email notification, type the
following command:
/usr/sbin/sendmail -v recipient_email "subject_text"
l On Windows, to send a notification email, type the following command:
smtpmail -s subject -h mailserver recipient1@mailserver
recipient2@mailserver...
where:
n -s subject—Includes a standard email header with the message and
specifies the subject text for that header. Without this option, the
smtpmail program assumes that the message contains a correctly
formatted email header and nothing is added.
n -h mailserver—Specifies the hostname of the mail server to use to relay
the SMTP email message.
n recipient1@mailserver—Is the email address of the recipient of the
notification. Multiple email recipients are separated by a space.

After the retention period expires, the save set is removed from the client file
index and marked as recyclable in the media database during an expiration
server maintenance task.
13. From the Client Override Behavior list, specify how NetWorker uses certain
client configuration attributes that perform the same function as attributes in
the Action resource:
l Client Can Override—The values in the Client resource for Schedule, Pool,
Retention policy, and the Storage Node attributes take precedence over the
values that are defined in the equivalent Action resource attributes.
Note: If the NetWorker policy action schedule is set to the Skip backup
level, the Client can Override option is not honored. For NetWorker to
consider the Client can Override option, change the action schedule to
a different level.
l Client Cannot Override—The values in the Action resource for the
Schedule, Destination Pool, Destination Storage Node, and the Retention
attributes take precedence over the values that are defined in the equivalent
Client resource attributes.
l Legacy Backup Rules—This value only appears in actions that are created
by the migration process. The updating process sets the Client Override
Behavior for the migrated backup actions to Legacy Backup Rules.
14. From the Success Threshold list, select one of the following to define the
success threshold for a save session:
l Warning—Save sets that complete with warnings are reported as success
with warnings.
l Success—Save sets that complete with warnings are reported as failed.
This is the default value. The number of times NetWorker retries a failed
save set is determined by the value defined in the Retries attribute.
15. Select Apply Lock under DD Retention Lock to enable retention lock for the
virtual machines included in this backup action. Note that the device used for
backing up these virtual machines must also have DD Retention lock enabled.
16. Use the Lock Period spin boxes to specify the duration the virtual machines will
remain on the Data Domain device before the retention lock expires.
17. Click NEXT.
18. Specify a weekly or monthly schedule for the action.
l To specify a schedule for each day of the week, select Weekly.
l To specify a schedule for each day of the month, select Monthly.
19. Click on each day to specify the type of backup to perform.
The backup levels for NetWorker includes the following:
l Full—Perform a full backup on the specified day. Full backups include all
files, regardless of whether the files changed.
l Incr—Perform an incremental backup on the specified day. Incremental
backups include files that have changed since the last backup of any type
(full or incremental).
l Cumulative Incr—Perform a cumulative incremental backup. Cumulative
incremental backups include files that have changed since the last full
backup.
l Logs Only—Perform a backup of only database transaction logs.
l Incremental Synthetic Full—Perform an incremental synthetic backup on
the specified day. An incremental synthetic full backup includes all data that
changed since the last full backup and subsequent incremental backups to
create a synthetic full backup.
To perform the same type of backup on each day, click , and select one of
the following:
l Make All Full
l Make All Incremental
l Make All Cumulative Incremental
l Make All Logs Only
l Make All Incremental Synthetic Full
l Make All Skip
20. (Optional) Select Override Options to configure overrides for the task that is
scheduled on a specific day.
Note: If you select this option, you must configure the overrides using
either fixed dates or recurring dates.
Note:
l You can select multiple override dates.
l In the case of a fixed date pattern, to clear an override schedule, click
on the day that you want to clear the override for and select Clear
Selection. The Clear Selection option is not applicable in the case of
a recurring pattern.
l If the fixed and the recurring pattern is on the same day, the fixed
pattern gets preference. However, if you clear the fixed override
schedule, the recurring pattern is displayed.
l When creating overrides, you cannot select the previous month and
year. You also cannot create fixed overrides for the days before the
current day because the option to change the level is disabled.
l When editing overrides, you can clear existing fixed overrides for the
days before the current day. However, you cannot set any new
overrides because the option to change the level is disabled.
l To abort the entire workflow if there is a failure with one of the jobs in the
action, select Abort Workflow.
30. In the Retries field, specify the number of times that NetWorker must retry a
failed probe or backup action, before NetWorker considers the action as failed.
If the Retries value is 0, NetWorker does not retry a failed probe or backup
action. The default value is 1.
31. In the Retry Delay field, specify a delay in seconds to wait before retrying a
failed probe or backup action. When the Retry Delay value is 0, NetWorker
retries the failed probe or backup action immediately. The default is 1 second.
32. In the Inactivity Timeout field, specify the maximum number of minutes that a
job run by an action can try to respond to the server.
If the job does not respond within the specified time, the server considers the
job a failure and NetWorker retries the job immediately to ensures that no time
is lost due to failures. The default value is 30 minutes.
Increase the timeout value if a backup consistently stops due to inactivity.
Inactivity might occur for backups of large save sets, backups of save sets with
large sparse files, and incremental backups of many small static files.
33. In the Soft Limit field, select the amount of time after the action starts to stop
the initiation of new activities. The default value of 0 (zero) indicates no amount
of time.
34. In the Hard Limit field, select the amount of time after the action starts to
begin terminating activities. The default value of 0 (zero) indicates no amount
of time.

Troubleshooting policies
This section provides information about issues related to the configuration and
management of policy resources.
Remote system error - Cannot assign requested address
This message appears intermittently when a single workflow has more 2000 save sets
and the backup and clone operations occur concurrently. In this scenario the number
RPC connections that the configuration requires exceeds the available number of RPC
ports. To resolve this issue, split the workflow with a large number of save sets into
multiple workflows, up to a maximum of 2000 save sets in each workflow and stagger
the workgroup start times by 30 minutes.
Unable to start because the Group for this workflow is empty
This message appears when you use the Start Individual Client option to start actions
for specific clients in the Server backup workflow. NetWorker does not support the
Start Individual Client option for the Server backup workflow. To resolve this issue,
start all actions for all the clients in the workflow.
Running actions from the command line
NetWorker 19.1 and later provide you with the ability to run actions from a command
line for debugging purposes only.
To debug an action, use the action binary, for example, nsrworkflow, nsrpolicy,
savegrp, or nsrnassnap_index with the following options:
l --policy_name—Specifies the name of the policy that contains the action. This
option is required.
l --workflow_name—Specifies the name of the workflow that contains the action.
This option is not required when a policy only contains one workflow.
l --action_name—Specifies the name of the action. This option is not required
when a workflow only contains one action.
l -Z action_type—Required for the savegrp binary. Specifies the action type of
the action. Supported values are backup:traditional, backup:snapshot and probe. If
you do not specify this option, savegrp defaults to the backup:traditional action
type.
l --driven_by_action—Specifies the source of the input work items for an action,
for example a list of backup save set. Sources include one of the following options:
n jobid—Specifies the jobid of the driving action.
n stdin—Instructs the action binary to read the items from stdin.
n file:absolute_path_to_file—Instructs the action binary to read the items from a
file.
Note: This option is only required when the action is not the first action in a
workflow.
In the following example, a backup of the save set /baz failed for host foo.com. The
name of traditional backup action for the save set is backup. A workflow named
traditional1, which is in a policy named Backup contains the action.

set entries are maintained in
the media database and client
file indexes.
Save sets
The collection of data items that are backed up during a backup session between the
NetWorker server and a Client resource is called a save set.
A save set can consist of the following:
l A group of files or entire file systems.
l Application data, such as a database, or operating system settings.
You can use the predefined save sets for scheduled backups, or specify a list of save
sets to back up for a client resource in the Save set attribute on the General tab of
the Client Properties dialog box.
Predefined save sets include the DISASTER_RECOVERY:\ save set and the ALL save
set.
When you specify a list of save sets for a client resource, the following guidelines
apply:
l For Windows operating systems, use the same pathname case that the Windows
file system uses. Although most file systems are case-independent, the NetWorker
software cross-platform indexing system is case-sensitive. Always specify the
Windows drive letter in uppercase.
l Place multiple entries on separate lines. For example, to back up a log file directory
that is named C:\Docs\CustomerLogs, and all data that is contained in a
directory that is named D:\accounting, type the following entries:
C:\Docs\CustomerLogs
D:\accounting
l For clients that use non-ASCII locales on UNIX platforms, or for Windows clients
that are configured from a UNIX host that uses non-ASCII locales, special
considerations apply when you type a path or file name in the Save set attribute:
n Type the path or file name in the locale that was used when you created the
path or file. If using a different locale when you type a path or file name,
backups fail with a No such file or directory error message.
n Either use the ALL save set in this situation, or log in to the client by using the
correct locale and then configure the client from that computer.
l To back up a UNIX or Linux host that contains path or file names with multiple
locales, create a separate Client resource for each locale. For example, to
configure a multi-locale UNIX host with data in both Japanese and French, create
two different Client resources. One Client resource to define the save sets for the
Japanese data, and one Client resource to define the save sets for the French
data.
UNIX l When the backup starts, the savefs process reads the
contents of the /etc/vfstab file on Solaris clients,
the /etc/fstab file on HP-UX and Linux clients, or
the /etc/filesystems file on AIX clients. The
contents of the file are compared to the currently
mounted file systems and BTRFS sub-volumes. Only
NOTICE When you use the ALL save set for a backup, the NetWorker software
creates a temporary file similar to a directive under each drive. The file name uses
the format drive guid.txt and lists the files that are excluded from the
backup. The file is temporary and is automatically deleted when the backup
completes.
Keywords for scheduled file system backups
You can use special keywords with the ALL save set to define the file systems to
include in a backup. The following table provides a list of the special ALL save sets and
the backup behavior.
Backup levels
You can specify the level of the backup to be performed during scheduled backups.
When you limit the frequency of full backups, you help maintain server efficiency while
still ensuring that data is protected. Different backup levels enable you to balance the
amount of time that is required to complete a backup with the number of volumes that
are required to recover from a disk failure.
The following table describes the available backup levels.
Incremental Results in the back up of the files that have changed since the
last backup, regardless of the level of the last backup.
Cumulative incremental Results in the back up of all files that have changed since the
last full backup.
Logs only Results in the back up of the transaction log for databases
that are created by a NetWorker module. For example, the
NetWorker Module for Databases and Applications, the
NetWorker Module for Microsoft, or the NetWorker Module
for SAP.
Synthetic full Results in the back up of all data that has changed since the
last full backup and subsequent incremental backups, to
create a synthetic full backup.
Skip Skips the scheduled backup. For example, you can skip a
backup on a holiday if no one is available to change or add
more media volumes.
Synthetic full l Faster than a full backup l High load on the storage
node
l Faster recovery
l Requires at least two
l Low load on the server,

l Uses the most volume
l Requires fewer volumes
space
for recovery
l Day 4—A cumulative incremental backup saves all files that have changed since
the full backup on Day 1.
Figure 39 Incremental and cumulative incremental backup levels
To recover all data from a disk failure on Day 4, you need the data from the full backup
from September 30 and the cumulative incremental backup on Day 4. You no longer
need the data from Day 1, 2, and 3, because the volume with the cumulative
incremental backup includes that information.
Performing synthetic full backups also reduces recovery time because the data is
restored from the single synthetic full backup instead of from the last full backup and
the incremental backups that follow it.
Synthetic full backups do not eliminate the requirement for full backups. It is
recommended to perform full backups on a monthly or quarterly basis, and limit the
number of incremental backups.
In this example, the synthetic full backup operation creates the incremental backup at
T4. Then a synthetic full backup is created by combining the full backup at T1 with the
subsequent incremental backups at T2, T3, and T4 to form a synthetic full backup at
T4 + Delta. The save set at T4 + Delta is equivalent to a full backup that is taken at T4.
The T4 + Delta represents a small time change of one or two seconds from the time of
T4, since two separate save sets cannot be assigned the exact same save set time.
For example, if T4 is created at 1334389404, then T4+Delta is created at 1334389405,
with a difference of one second.
The synthetic full save set includes only files that are covered by save sets up to T4 at
1334389404. The incremental backup after the synthetic full backup at 1334389405
includes all changes since 1334389404. Note that the synthetic full backup does not
include the changes since T4, since only one save set can exist at any particular time.
After a synthetic full backup is performed, the next synthetic full backup combines the
previous synthetic full backup and subsequent incremental backups.
Synthetic full backups include only the NetWorker server and storage node. If all the
data is on a few storage nodes, then the network overhead for creating the synthetic
full backup can be drastically reduced when compared to a traditional full backup of
the same save sets.
NOTICE Under most conditions, synthetic full backups can free network
bandwidth and client resources. However, a synthetic full backup might take
longer to run on the storage node than a full backup because incremental backups
are combined into a synthetic full backup. Without proper planning, synthetic full
backups might affect the performance of the storage node.

set ID (instead of the save set name), and the –t and –e options to specify the start
time and end time for the save set, respectively.
The value that you specify for a save set name, client name, file name, or directory
name with nsrconsolidate for a Windows client is case-sensitive because the
NetWorker software cross-platform indexing system is case-sensitive. A best practice
is to always specify the Windows drive letter in uppercase.
When you run multiple nsrconsolidate commands, run fewer commands that
include many save sets instead of multiple commands with fewer save sets. This
strategy helps nsrconsolidate to manage the number of concurrent synthetic full
operations and reduce resource usage. The best number of concurrent synthetic full
operations depends on the following criteria:
l Configuration of the NetWorker server.
l Size of the save sets and number of clients.
l Number of nsrpolicy instances that are concurrently running.
The NetWorker Command Reference Guide or the UNIX man pages provide details on
nsrconsolidate.

Support for concurrent operations
The volume of concurrent VSF operations that a Data Domain system can handle
depends on the model of the Data Domain system and the capacity of the NetWorker
host. The following scenarios have been tested and verified to work:
l Concurrent VSF backups.
l A VSF backup concurrent with a cloning operation.
l A VSF backup concurrent with clone-controlled replication.
mminfo –q syntheticfull –c client -N Queries all synthetic full save sets for the
save_set specified client and save_set.
Backup scheduling
When you schedule backups, you define the days on which backups occur and the
level of backup (full, incremental, and so on) that occurs each day.
Depending on the size of a network, you could perform full backups for all clients
simultaneously. For example, if no one works over the weekend you could schedule full
backups during this time.
Alternatively, you may need to configure backups to balance the backup load on and
increase the efficiency of a NetWorker server. Since full backups transfer large
amounts of data and typically take longer than other backup levels, you might want to
stagger them throughout the week. For example, you could configure backups so that
full backups occur for one group of clients on Sunday, for a second group of clients on
Tuesday, and a third group of clients on Thursday, as illustrated in the following figure.
Figure 42 Staggered weekly backup schedule for multiple groups of clients
Note: Consider using a synthetic full backup in environments with a short backup
window period when you must create a full backup.
period (that is, the retention setting is three months), then you must maintain all the
backup volumes for a three-month period. However, if users expect to be able to
recover data from only the last month, you do not need to maintain as many volumes.
Considerations for large client file systems
At a moderate backup rate of 400 KB per second, a full backup for a client with 10 GB
of data takes about seven hours to complete. Performing a scheduled full backup for
such large client save sets may not be convenient because of the amount of time
required.
For large client file systems, consider scheduling consider separate backups for each
of the client disk volumes. This strategy enables you to back up all the client files, but
not all at once, which is less time-consuming than a full backup of all local data at one
time.
To schedule separate backups of each client disk volume, configure multiple client
resources for the client, and explicitly list one disk volume as the save set for each
client resource. Add each client resource to a different group. Then configure
separate policy workflows to back up each group on a different schedule.
NOTICE When you create explicitly list save sets, any files or file systems not in
that list are omitted from the backup, including any new disk volumes that you add
to the system. Remember to configure backups for any new disk volumes after
you add them.
You can also configure the schedule for a backup action on a monthly basis instead of
on a weekly basis.
Click the icon in the schedule to change the backup level that is performed on that
day. The following table provides details about the backup level that each icon
represents.
Preconfigured schedules
When you override the policy backup schedule for a client resource, you can select or
customize one of the preconfigured schedules that are available when you install or
upgrade the NetWorker software.
The following table describes the preconfigured schedules.

Backup retention
The retention setting for a save set determines how long the NetWorker server
maintains save set entries in the media database and client file indexes. Until the
retention period expires, you can recover client backup data from backup storage
either by browsing the data or by recovering the entire save set.
Removing expired save sets on page 533 describes how to remove save sets from
backup storage after the retention period expires.

7. Click OK.
The following command updates the retention time for save set ID 3315861249 to
two years from the current date and time:
Renamed directories
When you rename a directory, a full backup is performed on all subdirectories and files
of the renamed directory.
If you then rename the directory back to its original name, then files and
subdirectories of the directory are not eligible for backup until the files or
subdirectories are updated or the next full backup occurs.
You can change this default behavior by clearing the Backup renamed directories
checkbox on the General tab of the Client Properties dialog box for a Client
resource. You must select View > Diagnostic Mode in the Administration interface to
access the Backup renamed directories attribute in the Client Properties dialog
box.
When you clear the Backup renamed directories checkbox for a Client resource,
unchanged files and folders under the renamed directory are skipped during a non-full
backup. This behavior can cause unexpected results during a recovery operation. If
you try to recover data under a renamed directory from a date between the time that
the directory was renamed and the next full backup, it may appear that data is
missing. For that recovery period, any files or folders that were unchanged do not
appear under the renamed directory. Instead, they appear under the previous
directory name.
You must leave the Backup renamed directories checkbox selected for clients that
perform synthetic full backups.
Raw partitions
The NetWorker software must have exclusive access to a file system to perform a raw
backup. Close as many applications as possible before doing a raw disk backup. If the
raw partition contains data that are managed by an active database management
system (DBMS), ensure that the partition is offline and the database manager is shut
down. For greater flexibility when backing up partitions that contain DBMS data, use a
NetWorker Module application.
Raw partitions on Windows
Back up raw disk partitions on Windows by specifying the raw disk partition in a save
set with the save command. Identify the raw partition as a physical drive or logical
drive. For example:
General tab of the Client Properties dialog box for the Linux Client resource. The
backup fails if you use the /dev/raw device.
by using the Parallelism attribute in the Client Properties dialog. The default value
for the Parallelism attribute is different for the NetWorker Server than it is for all
other Client resources:
l For the NetWorker Server Client resource, the default value is 12. This higher
default value enables the server to complete a larger number of index backups
during a file system backup of the server or other index backups.
l For all other clients, the default value is 4.
Enabling PSS results in significant performance improvements due to save set
aggregation, where the NetWorker Server starts a single save process per client with
all client save sets that are passed to the single process for various processing
optimizations, such as minimal Windows VSS snapshots and support for the following:
l Four parallel streams are started per save set, subject to any client parallelism
limitations that might prevent all save sets from starting simultaneously.
l The ability to modify the number of parallel streams per save set by defining the
new PSS:streams_per_ss environment variable save operations attribute in the
properties of a Client resource. For example, setting PSS:streams_per_ss=2,*
splits all save sets into two parallel save streams, whereas
PSS:streams_per_ss=3,/data1, 5,/data2 splits /data1 into three parallel save
streams and /data2 into five parallel save streams.
l Automatic stream reclaiming, which dynamically increases the number of active
streams for an already running save set backup to maximize utilization of limited
client parallelism conditions.
Note: It is recommended that you set the client parallelism value to be a multiple
of the PSS:streams_per_ss parameter default value 4 or its largest defined value
when configured. For example, a multiple of 4 is 8, 12, or 16.
Note: Starting with NetWorker 18.1 and later, the number of retries can be set
maximum up to 24 and retry delay can be set maximum up to 3600 seconds from
CLI only.
Troubleshooting PSS
About this task
It is recommended that you troubleshoot PSS with the guidance of Customer Service.
The NetWorker Performance Optimization Planning Guide provides complete details on
PSS requirements and performance benefits.
Procedure
1. Enable detailed logging for the client:
a. Specify the following value for the Backup command attribute on the Apps
& Modules tab of the Client Properties box:
save -v -D7 (or D9 for more detailed logging)
NetWorker l /nsr/logs/daemon.raw
server
l All log files in /nsr/logs/policy/policy_name/ workflow_name/
action_name_sequence#_logs/*
For example, /nsr/logs/policy/Silver/Filesystem/
Backup_032334_logs/*
l /nsr/tmp/savegrp.log
Open files
Open files are a problem that all data backup applications must solve. Open files that
are not backed up correctly represent a potential data loss. They might be skipped,
improperly backed up, or locked.
NetWorker can open files that are owned by the operating system and files that are
owned by a specific application.
When you use VSS technology with NetWorker to create snapshot backups of
volumes and exact copies of files, the backup includes all open files and files that
change during the backup process.
Files owned by the operating system
Most open files that are owned by the operating system can be backed up. However,
some applications can apply operating system locks to open files. These locks prevent
other applications, such as NetWorker software, from writing to or reading from the
open file.
The NetWorker software normally skips locked files and returns the following
message:
save: filename cannot open
Also, the operating system might return a permission denied error.
To back up locked open files, close any open files if possible. To automate this
process, create a pre- and postprocessing backup command that shuts down specific
applications, backs up the open files, and then restarts any applications after the
backup finishes.
You can also use Open File Manager to back up open files.
Files owned by a specific application
The NetWorker software cannot normally back up an open file that belongs to a
specific application, like a database. To back up these open files, use a NetWorker
Module. For example, use the NetWorker Module for SAP to back up open files in an
Oracle database.
Files that change during the backup
If a file changes during a backup, the NetWorker software displays the following
message in the Monitoring window:
warning: filename changed during save
To ensure that the changed file is backed up, either rerun the scheduled backup or
perform a manual backup of the file.
NetWorker Modules can back up these types of files correctly if they are files that are
related to the database that the module is backing up.
Data deduplication
Data deduplication is a type of data compression that removes duplicate information
to reduce the amount of backup data sent to storage devices and reduce the
bandwidth that is required for the data transport. You can implement data
deduplication of NetWorker backup data by storing backups on Data Domain Boost
deduplication devices.
Directives
Directives are resources that contain special instructions that control how the
NetWorker server processes files and directories during backup and recovery.
Directives enable you to customize the NetWorker software, maximize the efficiency
of backups, and apply special handling to individual files or directories.
Types of directives
There are three types of directives.
l Global directives—Stored as resources on the NetWorker server and can be
selectively applied to individual clients by using the Directive attribute of the
Client resource.
l NetWorker User local directive—On Windows clients only, users with local
Windows Administrator or Backup Operator privileges can create a local directive
in the NetWorker User program. A file that is named networkr.cfg on the client
file system contains the directive configuration information. NetWorker uses the
directive that is specified in the networkr.cfg during a scheduled backup, a
backup that is started with the NetWorker User application, and save operations
that do not include the -i option.
l Local directive files—User-created files named nsr.dir (Windows) or .nsr
(UNIX) anywhere on a client file system where they have permission to create
files. These directives apply only to the immediate data within the path where the
directive file is located.
If there is a conflict between directives, global directives are enforced over local
directives. Also, NetWorker User program local directives are enforced over local
directive files (nsr.dir files) on Windows hosts.
NOTICE If you use the Windows BMR feature, implement user-defined directives
with caution. Using such directives in directories with system state files can lead
to an incomplete BMR backup image and potentially render the BMR backup
image unusable. If you create user-defined directives, test the BMR backup image
to ensure that you can recover the Windows system state correctly.
where:
l The directive statement does not contain blank lines.
l directory_specification is the absolute path to the highest-level directory for
which the ASM in the directive applies.
l [+] is optional. The presence of the plus (+) sign indicates that the directive
recursively applies to the directory defined by the absolute path and all
subdirectories.
l ASM is the ASM that specifies the action to take on one or more files in the
current directory.
l pattern is a list of file or directory names, in the current directory on which to
apply the ASM.
The pattern can include multiple names that are separated by spaces, and
wildcards. Wildcards can replace a single character or string of characters.
Directive statements support the use of standard shell command interpreter file
matching patterns. You cannot specify lower-level subdirectories in the pattern.
That is, the pattern must not contain the Unix "/" or Windows "\" directory
separator.
Note: File names are case-insensitive for directives that are applied to
Windows clients.
l save_environment_keyword is a NetWorker keyword that controls how the
current ASM and subsequent ASMs that apply to the current directory and
subdirectories are applied in the directive statement.
l comment is a user-defined description of the directive statement. A hash (#)
character must precede the comment.
Note: If an ASM or pattern name includes a space, enclose the name or argument
in double quotation marks.
The UNIX man page and the NetWorker Command Reference Guide provides detailed
information about directives in the nsr and nsr_directive commands.
l Networker does not support symbolic links in skip directives. Symbolic links are
considered as regular files.
For example, the symbolic link for the file example.dbf is .example.dbf.To
skip the file .example.dbf, you must use +skip: .*.dbf.
l Do not use wildcards in Windows VSS source volume directory mount names.
Defining multiple directory specifications
l Directives that follow a directory specification apply the ASM action to that
directory until the next directory specification.
l Directory specifications that do not contain wildcards take precedence over
directory specifications that contain wildcards. For example, when a directive
encounters a directory that matches a wildcard directory specification and a non-
wildcard directory specification, the directive will only apply the action defined in
the ASM of the non-wildcard directory specification of the directory.
Defining mount points in the directory specification
Directory mount names of Windows VSS source volumes cannot contain wildcards.
For example, you cannot create a directory specification in the format << "*?:\data\*
\" >> . You must specify each drive letter, for example << "C:\data\*\" >>, and
create a separate directory specification for it.
Defining a directory specification for a Windows client system
l File and directory names are case-insensitive.
l If there is a colon (:) in the pathname, enclose the entire path in quotation marks.
Order of execution in the directive
The command that is listed first in the directive takes precedence over the rest of the
commands.
When the first command in the directive is compressasm, then all the files are
compressed. The skip command in the directive is ignored. Example
When the compressasm is positioned at the end of the directive, the commands in
the directive work in the order that is mentioned. The files specified with +skip are
skipped and the rest are compressed. Example
+skip: zzz_DUMMY*
+skip: *.tmp
+skip: .db2diag.log.swp
skip: tmp_mnt
+compressasm -gzip -1: * .* *.*
[ and ] Square brackets Forms an expression. Represents any of the characters enclosed within the square
brackets. For example, the following directory specification includes all user folders
beginning with A or D:
<< */*/users/[AD]*/tmp/ >>
! Exclamation Must be used directly after the opening square bracket in an expression, for
example, [!...]. Matches any single character except for the characters typed after
the !. For example, to match any single character except a, b, and c, type:
[!abc]
- Hyphen When a hyphen is used between two characters within square brackets, it indicates
a range inclusive of those two characters. For example, the following directory
specification includes all user folders beginning with A, B, C, or D:
<< */*/users/[A-D]*/tmp/ >>
Note: Wildcards directives are applied only by the save process in the scheduled
backup workflow. When you skip unwanted mount points using directory
specification wildcard directives with the save set keyword All, save processes
still run for the unwanted mount points. However, the save processes only log
messages that the contents of the mount points were skipped. For example: <<
*/TestFileSystem[5-9]?/ >> +skip: *.
Note: A space appears after the first asterisk (*) in the pattern.
This example uses the skip ASM to instruct the NetWorker server to skip all files that
are named *.o in the SRC directory and all subdirectories. It then uses the forget
keyword to instruct the server to not apply the skip ASM to the SYS subdirectory.
Both the G:\SRC and the G:\SRC\SYS directories must be explicitly specified on
separate lines in the client resource Save Set attribute.
Using the ignore save environment keyword
The following example allows directives in the HOMEDOC directory to be applied to the
preceding example for the ignore keyword:
When the compressasm is positioned at the end of the directive, the commands in the
directive work as expected. The files that are specified with +skip are skipped and the
rest are compressed. For example,
+skip: *.LRG
+skip: *.CAT
+skip: *.TLB
+compressasm -gzip -1: * .* *.*
Global directives
Global directives are stored as resources on the NetWorker server and can be
selectively applied to individual clients by using the Directive attribute of the Client
resource.
Global directives are listed when you select Directives in the expanded left pane of
the Server window in the Administration interface. You can add, edit, copy, and delete
global directives.

Depending on user privileges and the operating system version, the
networkr.cfg file is created in one of the following locations:
l If you are logged in with local Windows Administrator or Backup Operator
privileges, networkr.cfg is created in the root of the system volume
(usually C:\).
l If you are not logged in with local Windows Administrator or Backup
Operator privileges, networkr.cfg is created in %SystemDrive%
For example, the following directive statement skips the C:\TEMP folder on a
Windows system during a backup:

performing a CIS or Windows Search backup:
If you do not specify the ALL save set or the DISASTER_RECOVERY:\ save set in the
Save set attribute for the client, then include the databases as part of a file system
backup:
l To back up a DHCP database, include the %SystemRoot%\System32\dhcp
directory in the Save set attribute of the Client resource for the DHCP server.
l To back up a WINS database, use the Microsoft WINS administrative tools to
configure an automated backup of the WINS database to a local drive on the WINS
server. Then specify the path to the database backup on the local drive in the
Save set attribute of the Client resource for the WINS server.
Hard links
You can back up and recover files with hard links on a Windows client. However, the
hard links of files that are created by using a Portable Operating System Interface
(POSIX) application are not preserved during recovery.
Support for hard links is disabled by default to improve performance.
Backup and recovery of hard links is disabled by default to improve performance. To
enable backup and recovery of hard links on a client, select the Hard links checkbox
on the Globals (2 of 2) tab of the Client Properties dialog box for the Client
resource.
Enable diagnostic mode view by selecting View > Diagnostic Mode in the
Administration window to access the Hard links checkbox.
Microsoft DFS
You can back up and restore Microsoft Distributed File System (DFS) data.
Microsoft DFS is a Windows file system feature that enables you to create a
namespace of shared directories that are physically distributed across a network. With
DFS, you can organize a set of distributed directories logically, according to any
scheme you choose, to provide centralized access to files that reside in a variety of
locations.
DFS junctions
A DFS junction is a DFS root or link:
l A DFS root is a namespace for files and DFS links.
l A DFS link is a connection to a shared file or folder.
DFS junctions are file system objects, not files or directories. Therefore, the
NetWorker software does not treat DFS junctions the same as files or directories for
backup and recovery. However, DFS junctions appear as files and directories in the
NetWorker User program.
DFS backups with the ALL-DFSR save set
The All-DFSR save set includes all DFS related save sets for a backup. Unlike other
all-inclusive save set types, ALL-DFSR is not related to any particular file system.
ALL-DFSR backs up all components that are defined by DFS\FRS writers. Backups
fail if you specify ALL-DFSR for a system where DFS or FRS is not installed.
The syntax for this save set is ALL-DFSR. It is not case sensitive.
The ALL-DFSR save set does not support BBB. BBB only creates backups at the
volume level, and DFSR replication folders can be a subfolder, which creates a
conflict.
Synthetic full backup is not supported with ALL-DFSR.
The ALL-DFSR save set registers the corresponding writer and writer component
nodes under WINDOWS ROLES AND FEATURES. All Replication folders are restored
through these nodes.
Configuring a scheduled DFS backup
About this task
To avoid inconsistencies among the various save sets, configure a scheduled backup
that includes the DFS topology information, junctions, and destination directories.
Alternatively, you can use the ALL-DFSR save set.
NOTICE When a DFS client resource is run for the first time, the save set sizes
should be verified to ensure that they are correct.
To configure a scheduled backup for a DFS:
Procedure
1. In the Administration screen, include the following clients in the NetWorker
group that will back up the DFS:
l The DFS host server
l Any computer where remote DFS destination directories reside
l A domain controller (domain-based DFS only)
For example, you could create a NetWorker group named DFS, then make
each of the preceding clients a member of the DFS group.
2. Enter the following save sets in the Save Set attribute of the DFS host server’s
client resource:
l The DFS root. For example, C:\MyDfsRoot.
l DFS destination directories that reside on the DFS host. For example,
D:\MyLocalDir
Note: DFS destination directories are also be backed up if you enter the
entire volume (for example, D:\) in the Save Set attribute.
3. For clients where remote DFS destination directories reside, enter the
destination directory paths in the Save Set attribute. For example:
E:\MyRemoteDir
E:\MyOtherRemoteDir
E:\
optimized backup. However, it is not recommended that you use this setting because
recovery performance issues might result in an unusable backup. Note also that even
when optimized deduplication backup is enabled, NetWorker will not perform an
optimized backup when the backup path is a subdirectory of the volume, or the non-
optimized deduplication save option is specified in the Save operations field of the
Client resource.
NetWorker supports the data deduplication feature on Windows Server 2012,
Windows Server 2012 R2, Windows Storage Server 2012, and Windows Storage
Server 2012 R2. NetWorker does not support the feature on Windows 8 client
computers or computers that run the older versions of the Windows operating system.
On computers that run the Windows Server operating system, NetWorker supports
the feature on volumes that use the NTFS file system, which can be part of a fail over
cluster, including CSV volumes.
To back up and restore Windows Server deduplication volumes or files, you must use a
NetWorker 8.1 or later client. You can only restore deduplicated backups to computers
that run on supported versions of Windows Server that have the data deduplication
role enabled. The data deduplication role is a child role of File Services, which is a File
and Storage Services role.
Detecting deduplication in a backup
When a deduplication volume is backed up, you can verify the form of the data that
was backed up. This information is identified in the mminfo extended save set
attributes output. To show all extended save set attributes, use the mminfo output
flag -r attrs. Deduplication backups are indicated with
*MSFT_OPTIMIZED_DEDUP_ENABLED:yes.
The UNIX man page and the NetWorker Command Reference Guide provides detailed
information about the mminfo command.
Data Deduplication Backup and Restore
NetWorker supports two types of backup and four types of restores for data stored
on a deduplication volume.
Optimized full-volume backup
Optimized full-volume backups are the default backup type for Windows data
deduplication volumes. The backup type occurs when the non-optimized data
deduplication save option is not specified and the backup path is a mount point, drive
letter or full volume backup. NetWorker full, incremental, and synthetic full backups
are supported with Windows data deduplicated volumes.
The optimized data deduplication files that are part of the backup include:
l Windows data deduplication reparse points
l Chunk store containers and data deduplication meta data files
NetWorker backup does not differentiate whether a volume is configured for data
deduplication, except to add the media database attribute if the volume is
deduplicated. The media database attribute, *MSFT_OPTIMIZED_DEDUP_ENABLED,
is set to true and is saved as part of an optimized data deduplication volume save set.
For Windows BMR, the Windows Server 2012 and Windows Server 2012 R2 data
deduplication writer is not part of the system state. Additionally, data deduplication
volumes can be critical volumes and are supported with Windows BMR.
Unoptimized full and incremental backup
NetWorker creates an unoptimized data deduplication backup under the following
conditions:
l When you specify in the save set attribute of the client resource, a backup path
that is a subdirectory of the volume, except in the case where the subdirectory is
the root of a mount point.
l When you perform a manual backup of the client that does not make up the entire
volume.
l When you specify the string VSS:NSR_DEDUP_NON_OPTIMIZED=yes in the
Save Operations settings of the client resource. If the save operation flag is set to
yes the data deduplication backup is not optimized. If no string is present, or if the
attribute is set to no, a normal volume level backup is performed.
To add this string, perform the following steps:
1. From the NetWorker Administration window, select the Protection menu.
2. In the left navigation pane, select Clients, right-click the client, and then select
Modify Client Properties.
3. On the client Properties text box, select the Apps & Modules tab.
4. In the Save operations field, enter the string and attribute setting and then
click OK.
In an unoptimized data deduplication backup, all files are rehydrated before the
back up is performed. The deduplication chunk store directory is not backed
up.
Windows dedup backups, either optimized or unoptimized, will be corrupt if
they are backed up with VSS off.
Reasons to create an unoptimized data deduplication volume backup include:
l Support restores of a Windows Server 2012 and Windows Server 2012 R2 backups
to an earlier version of Windows Server.
l Support restores of a Windows Server 2012 Windows Server 2012 R2 backups to a
non-Windows computer.
l No support for selective file restores due to insufficient information about the save
set’s restore context.
l No support for save set recovery of a Windows Optimized Deduplication volume
backup. If you see the following sample error message, perform either a complete
save set restore or select files to restore to an alternate location:
Failed to recover save sets: Unable to relocate a Windows
deduplication save set, so will not recover save set
123xxxxxxx. Either restore the whole save set to its
original location or select the files to restore to an
alternate location using the Recover operation.
In the preceding sample error message, "123xxxxxxx" represents the save set ID.
Short filenames
You can back up and recover the short filenames that are automatically assigned by
the Windows filename mapping feature.
Windows filename mapping is an operating system feature in which each file or folder
with a name that does not conform to the MS-DOS 8.3 naming standard is
automatically assigned a second name that does. For example, a directory named
Microsoft Office might be assigned a second name of MICROS~2.
Backup and recovery of short filenames is disabled by default to improve performance.
To enable backup and recovery of short filenames on a client, select the Short
filenames checkbox on the Globals (2 of 2) tab of the Client Properties dialog box
for the client resource.
You must enable diagnostic mode view by selecting View > Diagnostic Mode in the
Administration window to access the Short filenames checkbox.
D:\mount_point_name1
D:\mount_point_name1\mount_point_name2
D:\mount_point_name1\mount_point_name2\ mount_point_name3
To include mount points in a manual backup with the NetWorker User program, select
the checkbox next to the mount point name within the host volume entry in the
Backup window.
To perform a manual backup of nested mount points and their data, perform a
separate backup for each mount point. When you select a mount point in the Backup
window, all files, directories, and nested mount points beneath the mount point are
selected by default. Before you start the backup, clear the checkboxes next to any
nested mount points. Then perform separate backups for the nested mount points.
Overview of VSS
If the NetWorker Module for Microsoft is installed on the client computer, information
in this chapter might be superseded by information in the NetWorker Module for
Microsoft documentation. The NetWorker Module for Microsoft Administration Guide
provides more information about the NetWorker Module for Microsoft.
Volume Shadow Copy Service (VSS) is a Microsoft technology that acts as a
coordinator among all the components that create, archive, modify, back up, and
restore data, including:
l The operating system
l Storage hardware
l Applications
l Utility or backup programs, such as NetWorker software
VSS allows for the creation of a point-in-time snapshot, or temporary copy, of a
volume. Instead of backing up data directly from the physical file system, data is
backed up from the snapshot. In addition, VSS allows for a single, point-in-time
capture of the system state.
NetWorker uses VSS technology to create snapshot backups of volumes and exact
copies of files, including all open files. Databases and files that are open due to
operator or system activity are backed up during a volume shadow copy. In this way,
files that have changed during the backup process are copied correctly.
Shadow copy (snapshot) backups ensure that:
l Applications can continue to write data to the volume during a backup.
l Open files are not omitted during a backup.
l Backups can be performed at any time, without locking out users.
Note: VSS backups do not use snapshot policies, which are required to perform
snapshot backups. The NetWorker Snapshot Management Integration Guide
documentation provides more information.
1. After the writer signals that it has prepared the data, VSS directs the writer to
freeze I/O to the selected volumes, queuing it for later processing.
2. VSS then calls a provider to capture the requested data.
3. The provider, which is either software-based or associated with particular
hardware (for example, a disk array), captures the prepared data, creating a
snapshot (or shadow copy) that exists side-by-side with the live volume. Provider
support on page 415 contains more information.
The process of creating a snapshot involves interaction with the operating system.
The amount of time it takes to create a snapshot depends on a number of factors,
including the writer activity taking place at the time. Once the snapshot is created, the
provider signals VSS, which tells the writer to resume activity. I/O is released to the
selected volumes and any queued writes that arrived during the provider's work are
processed.
The following figure provides a graphical representation of the VSS backup process.
Figure 45 VSS backup process
1. NetWorker software (the requestor) asks VSS to enumerate writers and gather
their metadata.
2. Writers provide an XML description of backup components and define the recover
method.
3. VSS asks which providers can support a snapshot for each of the required
volumes.
4. Requestor asks VSS to createsnapshot.
Provider support
By default, the NetWorker client always chooses the Windows VSS system provider
for backups. If you want to use a hardware provider or a specific software provider for
a particular NetWorker client, enter the following command in the NetWorker client
resource Save Operations attribute:
VSS:VSS_ALLOW_DEFAULT_PROVIDER=yes
When the previous command is specified for a NetWorker client, a backup provider is
selected based on the following default criteria as specified by Microsoft:
1. If a hardware provider that supports the given volume on the NetWorker client is
available, it is selected.
2. If no hardware provider is available, then if any software provider specific to the
given NetWorker client volume is available, it is selected.
3. If no hardware provider and no software provider specific to the volumes is
available, the Microsoft VSS system provider is selected.
Controlling VSS from NetWorker software on page 416 provides more information
about specifying VSS commands for a NetWorker client. VSS commands on page
418 provides information about other VSS commands.
NOTICE Windows Bare Metal Recovery backups always use the Windows VSS
system provider even if the VSS:VSS_ALLOW_DEFAULT_PROVIDER=yes
command is specified for the NetWorker client resource.
Troubleshooting hardware providers
If you have specified the VSS:VSS_ALLOW_DEFAULT_PROVIDER=yes command as
described in Provider support on page 415 and the hardware provider and NetWorker
are incompatible, try one of the following workarounds:
l Uninstall the hardware provider.
l Migrate any data that is backed up by the NetWorker client to a disk LUN (Logical
Unit Number), such as C:\, that is not controlled by a hardware provider. In this
way, the NetWorker client will backup all data using the software provider.
Be aware that if the NetWorker Module for Microsoft is installed on the client host,
then the previously mentioned workarounds may not be required. Refer to the
NetWorker Module for Microsoft documentation for details.
application or service that is being backed up. Writers do not play a role in backing up
the file system.
Writers are currently only available for active services or applications. If a service or
application is present on a system but is not active, information from its writer is not
available. Consequently, a writer can appear or disappear from backup to backup.
Also, NetWorker software maintains a list of supported writers in the NSRLA database
of the client computer. When backing up data, the software checks to ensure that
these conditions exist:
l The writer that is associated with the application is present on the system and
active.
l The writer appears on the list of supported writers in the NSRLA database.
l A user has not disabled the writer.
If these conditions are all true for a particular writer, NetWorker software defaults to
backing up data by using VSS technology. If any of the conditions are false for a
particular writer, the data that is served by that writer is excluded from the backup
operation.
List of supported writers
During a VSS backup operation, NetWorker software validates each writer against a
list of supported writers. As part of a software release, or between releases, there may
be updates to the list of supported writers. The NetWorker E-LAB Navigator provides a
list of the currently supported writers.
Although the server name is not required in the preceding command example, include
the name to ensure that the save command finds the correct server. Separate multiple
Save Operations commands with a semicolon (;).
The NetWorker Command Reference Guide provides more information about the save,
savefs, and nsrarchive commands.
Note: If you change the VSS setting on a client by using the Local Save
Operations dialog box or the command prompt, it does not affect that client’s
VSS setting on the server. Likewise, if you change a client’s VSS setting on the
server, it does not affect the Local Save Operations setting or the command-
prompt VSS setting on the client.
Globally disabling VSS
Use the nsradmin program to disable VSS for all clients globally or only for clients with
a certain Windows operating system.
About this task
To disable VSS for all NetWorker clients, perform the following steps:
Procedure
1. Log in as root or as Windows Administrator on the NetWorker server.
2. Create an input file for the nsradmin command. The input file eliminates
interactive prompting as each client gets updated.
3. Run the nsradmin command and specify the input file.
4. Create an input text file. For example, create a file that is named disable-vss-
nt.txt and type the following into the file:
Example 8 Example: Disable VSS for all NetWorker clientsExample: Disable VSS for all Windows
NetWorker clients
Example 8 Example: Disable VSS for all NetWorker clientsExample: Disable VSS for all Windows
NetWorker clients (continued)
1. Create a text file that is named disable-vss.txt , and then type the following
into the file:
nsradmin -i <path>\disable-vss.txt
1. Create a text file that is named disable-vss-nt.txt , and then type the
following into the file:
nsradmin -i <path>\disable-vss-nt.txt

full recovery on a target host. You cannot recover individual file system objects from a
Windows BMR backup.
Terminology
The following list provides a description of typical Windows BMR backup and recovery
terminology. The road map indicates which steps you must perform before you try a
Windows BMR recovery.
This chapter uses the following terms to describe NetWorker support for Windows
BMR technology:
Bare Metal Recovery (BMR)
The operation that restores the operating system and data on a host after a
catastrophic failure, such as a hard disk failure or the corruption of critical
operating system components. A BMR is an automated process that does not
require the manual installation of an operating system. NetWorker provides an
automated BMR solution for Windows that uses the Windows ASR writer and
other Microsoft VSS writers to identify critical volumes and perform a full
recovery on a disabled computer.
Offline recovery
A restore operation that is performed from the NetWorker Windows BMR boot
image. A BMR recovery is an offline recovery. You cannot select specific files or
save sets to recover during an offline recovery. You must perform an offline
recover to the same or similar hardware.
Online recovery
A restore operation that is performed from the NetWorker User interface or
recover command. An online recovery requires you to start the computer from an
installed operating system and enables you to recover only specific files or save
sets. The topic Recovering file system data provides more information about
online recoveries.
Application data
User data that an application creates, such as log files or a database. For example,
the application data of a SQL server includes databases and log files. You cannot
use Windows BMR to recover the application data. You must back up and recover
application data with NetWorker Module for Microsoft (NMM).
ASR writer
The Volume Shadow Copy Service (VSS) writer that identifies the critical data
that NetWorker must back up to perform an offline recovery.
Critical volume
One of the following:
l Any volume that contains files for an installed service. The volume can be
mounted as an NTFS directory. Exchange 2010 is an example of an installed
service, but the Exchange database and log files are not considered critical.
l Any parent volume with a mounted critical volume.
Recovery
The restoration of the operating system and data for a host after a catastrophic
failure, such as a hard disk failure or the corruption of critical operating system
components. The recovery operation might be an offline recovery (Windows
BMR) or an online recovery.
Non-critical volume
A volume that contains user data and does not contain installed applications that
run as a service.
User data
Data that users generate, typically for the purposes of a business function. For
example, a Microsoft Word document or an Excel spreadsheet. Windows BMR
does not back up or recover user data unless the data resides on a critical volume.
The simplest way to back up all user data is to specify the keyword All in the
backup save set of the client resource. You can recover user data online at any
time (on demand) or after a Windows BMR recovery operation.
WinPE
A bootable stripped-down version of the Windows operating system. The
NetWorker Windows BMR image contains a customized WinPE with NetWorker
binaries and a wizard to control the offline recovery process. WinPE does not
support writers, except for the ASR writer. Therefore, VSS writers are not
available with a NetWorker Windows BMR.
and recovery. Additional backup and recovery procedures are required to backup and
restore application data. The NMM documentation provides specific instructions on
how to backup and recover applications.
You can use Windows BMR to recover a backup from a physical host. You can also use
Windows BMR to recover a VMware virtual machine or VMware CD to a physical host,
VMware virtual machine, or a VMware CD.
NetWorker uses a special save set called DISASTER_RECOVERY:\, a subset of the
ALL save set, to backup all the data that is required to perform a Windows BMR.
NetWorker performs the BMR backup while the Windows operating system is active.
You can recover an offline BMR backup without first reinstalling the Windows
operating system. This action prevents problems that can occur when you restore
operating system files to a running version of Windows.
To support a NetWorker Windows BMR recovery, download the Windows BMR image
from Online Support website. This image enables you to create a bootable Windows
BMR ISO that contains NetWorker binaries and a wizard, which controls the recovery
process.
Note: The NetWorker E-LAB Navigator provides more information about operating
systems support for Windows BMR.
Components of the DISASTER_RECOVERY:\ save set
The DISASTER_RECOVERY:\ save set contains a group of component save sets that
are required to perform a Windows BMR recovery. A full backup of the
DISASTER_RECOVERY:\ save set contains the following components:
l All critical volumes.
l WINDOWS ROLES AND FEATURES:\ (a subset of the DISASTER RECOVERY:\
and ALL save sets).
l System Reserved partition.
l UEFI partition (if available).
NetWorker supports full and incremental backup levels of the
DISASTER_RECOVERY:\ save set. Also, when the Windows BMR recovery operation
recovers data from an incremental backup, the recovery operation recovers all
incremental backups.
The first time NetWorker performs a backup of the DISASTER_RECOVERY:\ save
set, NetWorker performs a level Full backup, regardless of the level that is defined for
the backup.
When you configure a level Incremental backup of the DISASTER_RECOVERY:\ save
set, NetWorker backs up some components of the save set at a level Full, and other
components at an Incremental level.
The following table summarizes the backup level of each save set component of the
DISASTER_RECOVERY:\ save set, when you perform an incremental backup:
During an incremental backup, the backup operation checks both the modification
time and the archive bit to determine if a file must be backed up. The backup
operation ignores the archive bit when you assign the nsr_avoid_archive variable a
value of Yes on the client host. As a result, NetWorker only uses the modification time
to determine which files to back up.
Use the environment variable nsr_avoid_archive with caution. If you use the
environment variable nsr_avoid_archive, test the BMR backup image to ensure that
you can recover the Windows system state correctly. Performing a BMR recovery to a
physical computer provides more information on validating the BMR backup image.
A Windows BMR recovery requires a successful backup of each component save set in
the DISASTER_RECOVERY:\ save set. If one component of the save set fails, then
the backup operation fails. For a scheduled backup, NetWorker retries the
DISASTER_RECOVERY:\ backup. The number of retries that NetWorker performs is
based on the value that is defined in the client retries attribute of the protection group
that the Client resource is assigned to.
Note: In NMC Administration GUI, the Log tab of the Monitoring window, or the
Save Set tab of the Media window displays each component save set of a
DISASTER_RECOVERY:\ backup.
Critical volumes
This topic describes critical volumes and the associated management tools.
NetWorker considers a volume as critical when it contains files for an installed
Windows service. NetWorker also considers the following volumes as critical and will
include the volumes in a DISASTER_RECOVERY:\ backup:
l A non-critical volume that has a critical volume mounted on it, or a non-critical
volume that serves as a parent to a critical volume.
l All volumes on a dynamic disk when one of the volumes critical. If one disk in a
dynamic disk pack is critical, then NetWorker must treat all disks in that pack as
critical. This can substantially increase the number of disks that NetWorker
includes in the BMR backup. It is recommended that you do not install services on
a dynamic disk.
Note: By default, the Windows 2012 System Writer does not report Win32 Service
Files as a part of systems components. As a result, the volumes that contain
Win32 Service Files are not considered critical and the DISASTER_RECOVERY:\
save set will not include a volume that contains files for an installed service. To
configure the Windows 2012 server to report Win32 Service Files as a part of
system components, set the ReportWin32ServicesNonSystemState registry sub
key to 0. Microsoft KB article 2792088 provides more information.
A Windows BMR backup does not back up the following files on a critical volume:
l Files listed in the FilesNotToBackup registry key.
l Files excluded by system writers.
l Files that an application VSS writer backs up. For example, Exchange databases.
Use NetWorker Module for Microsoft Applications (NMM) to backup these files.
NetWorker_install_path\bin>save -o VSS:LCV=yes
Output similar to the following appears:
The following volumes are determined as critical by the system
state writers:
C:\ (disk num 0)
i:\mount\ (disk num 7)
The following volumes are critical because they are parents for
one or more mounted critical volumes:
i:\ (disk num 2)
The following volumes are critical because they are in the
same dynamic disk pack with one or more critical volumes:
H:\ (disk num 4,5)
i:\ (disk num 2)
l Block Based Backups (BBB) do not support the WINDOWS ROLES AND
FEATURES save set.
l You cannot restore the WINDOWS ROLES AND FEATURES save set
simultaneously with data from a file system backup. If you must recover data from
both the WINDOWS ROLES AND FEATURES backup and a file system backup,
restore the file system data first, and then restore the WINDOWS ROLES AND
FEATURES data.
l The NetWorker software automatically backs up AD as a component of the
WINDOWS ROLES AND FEATURES save sets. An AD backup or restore includes
the AD log files, database, patch files, and expiry token.
l You can perform an online recovery of the WINDOWS ROLES AND FEATURES
save set to recover the Active Directory, DFSR, or Windows Server Failover
Cluster services. The topic Online recovery of Active Directory, DFSR, or Cluster
service provides more information.
l If you cancel a deduplication recovery, the state of the recovered data is not
reliable and may contain corrupted data. To ensure that the recovery is correct,
restart the deduplication recovery process.
l The backup operation only confirms that the VSS System Writer exists on the
target host. If the backup operation does not detect the writer, the backup of the
DISASTER_RECOVERY:\ or ALL save set fails. The backup operation does not
track and report any other missing VSS writers.
l You can perform a component level granular restore of the WINDOWS ROLES AND
FEATURES save set with a command line recover or the NetWorker User
application. For example, you can recover the system state and replication folders
separately. You cannot use the NMC Recovery UI to perform a component level
restore.
l Do not restore the WINDOWS ROLES AND FEATURES system state multiple times
in succession without restarting the computer as required. If you do not restart
the computer, you can put the system in an unreliable operational state.
Note: The NetWorker 8.2 and later clients can only recover WINDOWS ROLES
AND FEATURES save sets. If you try to recover a VSS System State save set that
was created with a NetWorker 8.0 SP1 client or earlier, then the Windows host will
not function correctly. To recover VSS system state save sets that are created
with a NetWorker 8.0 SP1 or earlier backup, use the NetWorker 8.0 SP1 or earlier
client to create a backup. It is recommended that you restore the WINDOWS
ROLES AND FEATURES save set from a NetWorker 8.1 or later backup.
the CSV is not on the critical list. NetWorker does not backup the CSV because a CSV
cannot reside in the same shadow copy set with a local volumes.
Applications such as SQL Server and Hyper-V in a Windows Continuous Availability
scenario using CSV are not supported.
The NetWorker Cluster Integration Guide provides more details.
The save set attribute of the Client resource contains the ALL save set and the
backup schedule includes a synthetic full backup on Sundays. The NetWorker client
host has four volumes: two are critical, and two are non-critical.

NetWorker does not support the online recovery of any other Windows service that
the WINDOWS ROLES AND FEATURES save set contains. Unsupported online
recovery of WINDOWS ROLES AND FEATURES components results in an inconsistent
state of the Windows server.
NOTICE When you perform an online recovery, you cannot mark the WINDOWS
ROLES AND FEATURES save set and use the Required Volumes option. To
determine the volume that contains the WINDOWS ROLES AND FEATURES save
set that you want to restore, mark the DISASTER RECOVERY:\ save set, then
use the Required Volumes option. After you determine the required volumes,
unmark the DISASTER RECOVERY:\ save set and mark the WINDOWS ROLES
AND FEATURES save set.
l The target system can access the Windows BMR image as a bootable CD/DVD
volume or from a network start location.
l The target system has the NIC or storage device drivers installed that match the
NIC.
Note: All NIC or storage device drivers must not require a restart to complete
the driver installation process. If the drivers require a restart, then the BMR
recovery process fails and prompts you to install the drivers again.

where:
save_set1 or save_set2 are unique save set names, such as a drive letter (f:\) or
mount point (n:\mountpoint).
Monitoring save operations
When you monitor Windows BMR save operations, for example, by using the
NetWorker Administration > Monitoring > Sessions window, you might notice that
the number of save sessions differ from the number of save sets that appear in the
Save set attribute of the Client resource. This is because NetWorker optimizes
Windows BMR backups to generate the correct number of Windows BMR backup
sessions and save sets.
Cloning considerations
To clone a Windows BMR backup, ensure that you clone all of the critical volumes,
DISASTER_RECOVERY:\, and WINDOWS ROLES AND FEATURES save sets that
were created during the backup operation. While you can clone individual save sets,
you cannot perform a successful BMR recovery unless you recover each save set that
the backup operation created.
To ensure that you clone all of the BMR save sets, review the following information
before you start a clone operation:
l When you use the automatic clone, you enable the Clone attribute on the group
resource that contains the BMR client. The automatic clone operation will clone all
of the required save sets after the scheduled backup operation completes.
Note: Synchronize the NetWorker server and client host clocks before the
backup operation to ensure that all of the save sets are cloned.
l When you use the nsrclone command to perform a manual clone, ensure that
you include the ssid/cloneid for each save set. Use the mminfo or nsrinfo -v
command to report all save set backups that occurred for the Windows client
during the save session. The Command Reference Guide provides detailed
information about using the mminfo and nsrinfo commands.
l When you use the schedule clone function, do not filter on other attributes such as
save set name. Filter only by client name. When you enable automatic cloning for a
backup group that contains the DISASTER_RECOVERY:\ save set, synchronize
the clocks on the NetWorker server and client host clocks across the network to
ensure that NetWorker clones all save sets.
Security considerations
This section describes security issues related to planning Windows BMR backup and
recovery.
NetWorker support for Windows Encrypting File System (EFS)
This topic describes the behavior of EFA and BitLocker after you complete a BMR
with NetWorker.
Windows BMR supports backup and recovery of files and folders encrypted with
Windows Encrypting File System (EFS), and volumes encrypted with BitLocker. After
BMR, the EFS or BitLocker services might be running but the EFS encryption
attributes on files or folders must be re-enabled and BitLocker volumes must be re-
encrypted. Consult Microsoft documentation for steps to encrypt with EFS and
BitLocker.
If a folder is encrypted in Windows, for example, by selecting Folder Properties >
Advanced > Encrypt contents to secure data, it is recovered as encrypted. However,
the encryption attribute is not be set on the folder. You can manually reset the
encryption attribute after the recovery operation. This is a Microsoft limitation.
Windows BMR and third-party encryption tools
This topic provides information on how to correctly validate Windows BMR when you
use a third-party encryption tool.
NetWorker Windows BMR has not been thoroughly tested with third-party drive
encryption products other than Microsoft's BitLocker. If you use a third-party drive
encryption product, then validate the backup and recovery procedures by performing
a Windows BMR backup and recovery to verify that the restored computer is fully
functional. Perform the test against the original hardware and new hardware to
confirm both scenarios. You must learn if any additional steps are required to
reencrypt the drivers after a successful restore.
NetWorker Strong Authentication and Windows BMR recoveries
This topic describes how to use NetWorker strong authentication.
Note: Starting with NetWorker 19.1, BMR can be performed for clients that uses
nsrauth as authentication method.
When you recover a Windows client that uses NetWorker strong authentication
(nsrauth) to communicate with other NetWorker hosts, communications with the
NetWorker server may fail during a Windows BMR recovery. When you perform a
Windows BMR recovery for a host that uses nsrauth authentication only, the Windows
PE image does not have the nsrauth credentials file that the original client used, and it
generates the new credentials. NetWorker server refuses to allow the recovery
operation to complete as it is not aware of the new credentials.
To resolve this issue, before you perform the BMR recovery perform the following
task:
l Delete the NSR Peer Information resource for the NetWorker Client from the
NSRLA database on the NetWorker Server. This will cause the NetWorker Server
to create a new NSR Peer Information resource for the client.
Note: The SQL Server installation media contains the Setup tool.
l Before you start the Windows BMR recovery operation, ensure that you detach
the shared disks. After the Windows BMR recovery operation and the restart
completes, attach the shared disks before you perform the online recovery.
l After an authoritative restore completes, the recovery operation does not bring
the cluster services online on the remote nodes. You must bring the services online
manually.
8. Click Next.
9. On the Specify the Backup Configuration Type window, select Filesystem,
and then click Next.
10. On the Select the NetWorker Client Properties window, configure the
following options:
Option Description
Priority Enables you to control the order in which the NetWorker server
contacts clients for backup. During a backup operation, the
NetWorker server contacts the client with the lowest priority
value first. If you do not specify a priority for the client
resources, then the backup order is random. The default value
is 500.
While the Priority attribute specifies the order of client contact,
many variables affect the order in which clients complete their
backups. For example:
l The backup operation on a client does not begin until the
worklists for each of the save sets on the client are
complete.
l The amount of work can vary greatly from one client to the
next.
l If a client stops responding and times out, then the backup
operation puts the client backup at the end of the backup
order list.
The only way to guarantee that the backup of one client occurs
before the backup of another client is to configure the
workflows for the clients to start at different times.
Option Description
number of physical disks on the client that are included in the
backup.
The NetWorker Performance Optimization Planning Guide
provides more information about recommended client
parallelism values and performance benefits.
Remote Specifies a list of the users that have access to perform remote
Access access operations. For example, users that can perform a
directed recovery of backup data that originated on this host.
Data Domain Specifies the protocol to use if you send the backup data to a
Interface Data Domain Device. Available selections are IP, Fibre Channel,
or Both.
Note: Mac OS X clients only support the IP protocol.
Block Based Enables Block Based Backups for the host. When you select
Backup this option, you must also select the Client Direct.
(BBB) This option applies to Linux only.
Note: The Block Based Backup chapter provides complete
information about how to configure a host for BBB
backups.
Client Direct Allows the client to try to directly connect to the backup
storage device, instead of connecting to a NetWorker storage
node. If a direct connection is not possible, then the backup
operation connects to the NetWorker storage node that you
configure to accept data from the client.
2. Click Recover.
The Source Client dialog box appears.
3. Select the source client of the DISASTER_RECOVERY:\ save set, and then
click OK.
4. Select a destination client, and then click OK.
5. In the Recover window, browse and locate the save set named
DISASTER_RECOVERY:\.
where:
l server_name is the name of the NetWorker server.
l client_name is the name of the client that performed the Windows BMR backup.
l If DNS is not available, that the host can resolve the NetWorker server name
by some method, such as a local hosts file.
l You can see the network interface that is required to communicate with the
NetWorker server. If you cannot see the network interface, use the wizard
to load the required NIC driver.
l You can see the critical and non-critical disks for the host that is to be
recovered. If you cannot see all of the disks, use the wizard to load the
required disk drivers.
Mapped drives
To back up mapped or CIFS drives on a Windows client for either a scheduled or a
manual backup, you must perform additional configuration steps in the Client
resource.
Before you begin
l Create a dedicated client resource for the backups of mapped drives. A common
user account must have access to each mapped drive.
l Create a separate Client resource for backups of local drives.
l Ensure that the Administration window is in Diagnostic Mode. To enable
Diagnostic Mode, from the View menu, select Diagnostic Mode.
Procedure
1. In the NetWorker Administration window, click Protection.
2. In the expanded left panel, select Clients.
3. Right-click the client resource and select Modify Client Properties.
The Client Properties dialog box appears.
4. On the General tab, in the Save set attribute, specify the Universal Naming
Convention (UNC) path of the drive.
Do not specify the drive letter. For example, to specify the accounts directory
on the jupiter server, type \\jupiter\accounts.
5. On the Apps & Modules tab, configure the following attributes:
a. In the Remote user and Password fields, specify a username and the
associated password for an account that has access to the UNC path.
b. In the Backup command box, type save -xL.
c. In the Save operations box, type VSS:*=off
Linux
You can install the NetWorker client, server, storage node, and NetWorker
Management Console (NMC) server software on Linux.
Backup and recovery operations are supported on the following Linux journaled file
systems:
l ext3
l reiserfs
l jfs
l xfs
For ext3 file systems with the journal set to visible, do not back up or recover the
journal. Recovering the journal may cause the file system to become unstable. Use a
directive to ensure that the file system is excluded from a backup. Directives on page
388 provides information on directives.
Solaris
You can install NetWorker client, server, storage node, and NetWorker Management
Console (NMC) server software on the Solaris platform.
The NetWorker software supports local and global zones for a NetWorker client,
server, and a dedicated storage node. You can install and back up a NetWorker client,
server, or storage node on a computer running in a local zone. The NMC and
NetWorker License Manager can only be installed in a global zone.
Note: Extended file attribute data is in the calculation of the save set file size for
Solaris clients. As a result, the save set file size in NetWorker appears to slightly
larger than expected.
NetWorker executables not found for Solaris client
On Solaris client computers, NetWorker executables are installed by default in /usr/
sbin. The search path for root on the NetWorker server must include /usr/sbin.
Otherwise, scheduled backups fail on a client with NetWorker executables in /usr/
sbin because the savefs command is not in the search path.
To solve this issue, edit the search path for root on the NetWorker server to
include /usr/sbin, even if the directory does not exist locally.
Alternatively, specify /usr/sbin in the Executable path attribute on the Globals (2
of 2) tab of the Client Properties dialog box for the Client resource.
HP-UX
You can install NetWorker client, server, storage node, and NetWorker Management
Console (NMC) server software on the HP-UX platform.
Customized backup scripts
On HP-UX, do not use the posix shell (/bin/sh) for customized backup scripts that
are meant to be automatically started by the backup. Use the korn shell (/bin/ksh)
instead.
Symbolic link entries in the fstab file
For HP-UX operating systems, do not use symbolic link entries in the /etc/fstab
file. If you use symbolic links in the fstab file, the backup does not include the file
system to which the symbolic link points.
AIX
You can install the NetWorker client, server, storage node, and NetWorker
Management Console (NMC) server software on the AIX platform.
Note: On AIX, non-root users who are performing a recovery cannot restore group
ownership (the set-group-id-on-execution or setuid permission bit) on
binaries or files. This behavior is to be expected.
For application cluster hosts, type the FQDN of the application cluster host. For
example:
l For an Oracle cluster, type the RAC hostname.
l For an Exchange IP DAG, type the DAG name.

Backup this option, you must also select the Client Direct.
(BBB) This option applies to Linux only.
Note: The Block Based Backup chapter provides complete
information about how to configure a host for BBB

Client Direct Allows the client to try to directly connect to the backup
storage device, instead of connecting to a NetWorker storage
node. If a direct connection is not possible, then the backup
operation connects to the NetWorker storage node that you
configure to accept data from the client.
Option Description
Parallel Save Enables NetWorker to use multiple parallel save streams to
Streams backup each save set defined for the client, to one or more
(PSS) destination devices. PSS does not support Checkpoint Restart
backups.
The following file systems are excluded from the ALL save set. If you manually define
the file system or directories and files for one of these file systems in the Save set
attribute of the Client resource, the backup operation excludes the object:
l For a Solaris sparse or whole root zone client, all mounted file systems in the
sparse or whole root zone that are not normally skipped, such as NFS, are backed
up.
l ZFS file systems are backed up.
l If the save set name includes a symbolic link, a save set recovery is not supported.

on the physical host are skipped.
Note: If you explicitly list a BTRFS sub-volume in the Save set field,
NetWorker will back up the files in the sub-volume, even if the sub-volume
does not appear in the /etc/fstab file. When NetWorker encounters a
sub-directory that has a sub-volume ID that differs from the parent sub-
volume ID, NetWorker will not backup the contents of the subdirectory,
unless you specify the save -x in the Backup command. To back up data
in the subdirectories, perform one of the following tasks:
l Specify save -x in the Backup command field in the client properties
window.
l Explicitly list the path of each sub-volume in the Save set field.
l Mount each sub-volume, include the mount point in the /etc/fstab
file, and then specify ALL or all-btrfs in the Save set field.

Option Description
The default value is different for the NetWorker server than it
is for all other client resources:
l For the NetWorker server client resource, the default value
is 12. This higher default value enables the server to
complete a larger number of index backups during a Server
backup action.
l For all other clients, the default value is 4.
To avoid disk contention for clients other than the NetWorker
server, specify a value that is the same as or fewer than the
number of physical disks on the client that are included in the
backup.

Platform requirements
Checkpoint restart is only supported on Linux and UNIX environments when
performing standard save operations. You cannot use checkpoint restart with block-
based backup or parallel save streams enabled.
Checkpoint restart is not supported on Windows platforms.
Client hostname requirements
Use a consistent convention for all NetWorker client hostnames. Do not configure
client resources with both short and fully qualified domain names (FQDN).
Save set requirements
Backup of the Windows DISASTER_RECOVERY:\ save set is not supported. If a client
with a DISASTER_RECOVERY:\ save set is enabled for checkpoint restart, the
backup fails.
The checkpoint restart option is ignored for index and bootstrap save sets.
Client Direct requirements
Checkpoint restart supports Client Direct backups only to AFTD devices, and not to
DD Boost devices. If a client is enabled for checkpoint restart and a Client Direct
backup is attempted to a DD Boost device, then the backup reverts to a traditional
storage node backup instead.
For Client Direct backups to AFTDs, checkpoints are made at least 15 seconds apart.
Checkpoints are always made after larger files that require more than 15 seconds to
back up.
Performance requirements
Enabling checkpoint restart might impact backup speed, depending on the datazone
environment and configuration.
Checkpoint restart also might increase the size of the index because additional index
records are created for the valid recoverable data. These partial save sets should not
be manually removed from the index.
f. On the Action Wizard Summary page, review the settings for the backup
action, and then click Configure .
for a checkpoint-enabled client, and the backup is automatically restarted from the
checkpoint until the specified number of retries has been exceeded.
The automatic restart must occur within the restart window that you specify for the
workflow for the data protection policy.
Example 1
There are six clients in a group, each with three save sets. The Retries attribute for
the backup is 1. One save set fails and is checkpoint restarted immediately. The
remaining save sets in the group continue to back up. The save set fails a second time.
A checkpoint restart for the save set does not occur because the retry attempt would
exceed the value for the Retries attribute.
When all the save set backup attempts in the group complete, the backup completion
report:
l Provides a list of the successful save sets.
l Reports that the failed partial save set is unsuccessful.
l Reports that the backup failed.
Example 2
There are six clients in a group, each with three save sets. The Retries attribute for
the backup is 2. One save set fails and is checkpoint restarted immediately. The
remaining save sets continue to back up. The partial save set fails a second time and is
checkpoint restarted immediately. This time, the partial save set succeeds.
When all the save set backup attempts in the group are complete, the backup
completion report:
l Provides a list of the successful save sets.
l Reports that the two partial save sets are successful.
l Reports that the backup completed successfully.
The steps to recover data from a single partial save set are the same as save set
recovery from a complete save set. The partial save set contains only files that were
successfully backed up. You cannot browse partial save sets.
When you perform a save set recovery of a partial NDMP save set, the recovery
process recovers all partial save sets in the checkpoint sequence. You cannot recover
data in a partial save set separately from other partial save sets in the checkpoint
sequence.
Use the nsrinfo command to display the contents of a partial save set.
Probe-based backups
You can configure the NetWorker server to search or probe a NetWorker client for a
user-defined script before the start of a scheduled backup operation. A user-defined
script is any program that passes a return code.
About this task
When the NetWorker server detects the script, the NetWorker server runs the script
and interprets two return codes:
l Return code 0 indicates that a client backup is required.
l Return code 1 indicates that a client backup is not required.
NetWorker interprets all other return codes as an error and does not perform a
backup.
Procedure
1. Create the Probe resource script, and save the script in the same directory as
the NetWorker binaries on each client that uses the client probe.
The name of the probe script must begin with save or nsr.
Note: Users are responsible for creating and supporting user-defined
scripts.
f. Click OK.
3. Associate the probe with a Client resource:
a. In the expanded left pane of the Protection window, select Clients.
b. In the right pane, right-click the Client resource, and select Modify Client
Properties.
The Client Properties dialog box appears.
Encryption
You can use either AES encryption or in-flight encryption to encrypt data.
The Advanced Encryption Standard feature (AES encryption) encrypts data both in
transit and at rest on the backup volume.
In-flight encryption secures data that is in transit.
Note: Do not use the in-flight encryption feature and the AES encryption feature
together. Combining the encryption types is redundant and could significantly
increase the duration of the backup.
AES Encryption
You can apply password protection and 256-bit data Advanced Encryption Standard
(AES) encryption to backup and archive data on UNIX and Windows hosts for
additional security.
Note: You can apply password protection alone, AES encryption alone, password
protection and encryption together, or compression alone. You cannot apply
password protection and compression together or encryption and compression
together. Do not apply AES encryption and in-flight encryption together.
When NetWorker uses aes to encrypt the backup data, backup times increase. The
process of encrypting the data increases CPU and memory usage on the backup
client. The impact to CPU and memory resources depends on a number of factors
including the load on the host, network speed, and the number of backup files. A
backup of a single large file requires less resources than a backup of a dense file
system, where NetWorker must access a large number of small-sized files.
Do not use the aes ASM for data encryption when backing up files that are encrypted
by using the Microsoft Windows Encrypting File System (EFS). The backup is
reported as successful, but recovery of the file fails and the following message is
written to the NetWorker log file:
recover: Error recovering
filename. The RPC call completed before all pipes were
processed.
When a backup includes EFS encrypted files, the files are transmitted and stored on
backup volumes in their encrypted format. When the files are recovered, they are also
recovered in their encrypted format.
Password protection
AES Encryption is supported through the use of the aes Application Specific Module
(ASM) based on the password that is defined on the UNIX or Windows host. If a
password is not defined on the host, then data is encrypted with the default password
that is configured for the NetWorker server.
NOTICE You must specify the password to recover password-protected files. If
the password was configured or changed after the backup occurred, then you
must provide the password that was in effect when the file was originally backed
up. Keep password changes to a minimum.
In-flight encryption
In-flight encryption secures data that is in transit. By default, the in-flight encryption
feature is not enabled in NetWorker.
About this task
Backup times might be longer with in-flight encryption than with AES encryption.
Because in-flight decryption occurs on the target NetWorker storage node, CPU and
memory usage could significantly increase. The impact to CPU and memory resources
depends on a number of factors including the load on the host, network speed, and
the number of backup files.
You can enable in-flight encryption from the NMC or from nsradmin.
Note:
l Do not use the in-flight encryption feature and the AES encryption feature
together. Combining the encryption types is redundant and could significantly
increase the duration of the backup.
l Do not use in-flight encryption to backup and recover to Data Domain devices
(DDBoost). Refer to the Data Domain documentation set to configure
DDBoost encryption.
l In-flight encryption is not supported for a client direct backup and recovery
operation from a NetWorker client host over a network to a remote host's
AFTD. If in-flight encryption is enabled, data is not encrypted in-flight over the
network.
Use AES encryption for a client direct save operation from a NetWorker client
host over a network to a remote host's AFTD.
nsradmin -p nsrexec
4. Change the value of the connection encrypted attribute in the NSRLA resource
to enabled.
Type the following line at the nsradmin prompt:
Compression
You can compress backup data to reduce network traffic and backup storage
requirements.
Compressing data for a backup generates less network traffic. However, compression
uses computing resources, so its benefits may be limited on low-powered systems. If
the storage device also compresses data, the result may be that more data is actually
written to tape.
Note: You can apply password protection alone, encryption alone, password
protection and encryption together, or compression alone. You cannot apply
password protection and compression together or encryption and compression
together.
Procedure
1. Configure a password on the Windows host.
a. Open the NetWorker User program.
b. Select Options > Password.
c. Type the password in the Password dialog box and click OK.
2. Open the NetWorker User program and click Backup.
3. Select the data to back up.
4. From the File menu, select Special Handling.
The Special Handling dialog box appears.
5. Select Compress as the handling method for the backup data.
6. Click OK.
7. Click Start to start the backup.
For Client Direct backups to AFTDs, checkpoint restart points are made at least 15
seconds apart. Checkpoints are always made after larger files that require more
than 15 seconds to back up.
l Archive operations are not currently supported for Client Direct backups.

1. Use a text editor to create a script in the networker_installation_dir
\bin directory on Windows clients or the
networker_installation_dir/bin on LINUX or UNIX clients.
The script file must meet the following requirements:
l The name starts with save or nsr.
l The name contains a maximum of 64 characters.
l For Windows, the script file must end with a .bat extension.
l For UNIX, the script file must have executable file permissions.
For example, script file names that meet these criteria include
save_custom_script.bat and nsr_backup_script.bat for windows,
and save_custom_script.sh and nsr_backup_script.sh for Linux and
UNIX.
Reporting policy status and backup job status on page 679 provides more information
about how to review backup job status.
The netstart.txt and set.txt files are placed in the C:\directory. New
information is appended to these files each time a backup is run.

There are three check boxes for the Job control attribute:
l end on job end
l end on process exit
l use process exit code
The following table provides details on exit status reporting depending on the selection
of one or more of the checkboxes.
Selections Description
No selections The nsrpolicy and nsrjobd programs determine the success or
(default behavior) failure of a custom script based on the completion of the save
program (end of job). The following criteria apply:
l If the save job completion status is success, then nsrpolicy
and nsrjobd report that the custom backup job succeeded.
l If the save job completion status is failure, then nsrpolicy and
nsrjobd report that the custom backup job failed.
l If no completion status is received, the custom job output is
examined for completed savetime=savetime lines. If found
and the savetime is a value other than 0 (zero), then the
custom backup job is considered to have succeeded. If the value is
0, then the custom backup job is considered to have failed.
The exit code of the custom script process is not taken into
consideration.
end on job end only A backup job is considered to be ended as soon as an end job message
is received from the save command.
Select this option when you do not want to wait for the postprocessing
commands of the script to end.
end on process exit A backup job is considered to be ended as soon as the started process
only exits. Background processes started by the backup command could
still be running on the client.
Use this option when you want the custom script to start background
processes and you do not want savegrp or nsrjobd to wait for the
processes to complete.
use process exit Only the process exit code is used to determine the success or failure
code only of the job. An exit code of 0 indicates success. Otherwise, the job is
reported as failed.
Use this option when you want the script postprocessing command
status to have an impact on the status of the save backup command
without having to unset the NSR_STD_MSG_FD environment variable.
If the script invokes more than one NetWorker backup command such
as save, then you must still unset the NSR_STD_MSG_FD environment
variable.
Both end on job end Either event can trigger the end of a job.

Selections Description
Both end on job end If an end job message is received before the process exits, then the
and exit status provided by the end job message is used to determine the
use process exit success or failure of the job.
code
5. Optionally, in the Post command attribute, specify the name of the script file
that you require NetWorker to run after a backup of all the save sets for the
client completes.
Note: Do not specify the path to the file.
6. Click OK.
Results
The customized instructions are applied the next time that the client is backed up.
Client resources
A client is both a physical computer with NetWorker client software installed on it and
a NetWorker resource that specifies a set of files and directories to be in a scheduled
backup. A Client resource also controls backup settings for the client, such as the save
sets to back up for the client, the groups to which the client belongs, and whether to
automatically restart failed backups for the client.
You can configure multiple Client resources for a single NetWorker client computer,
although clients with the same save set cannot be in the same group. You might want
to create multiple Client resources for a single client computer in the following
scenarios:
7. To allow a failed backup operation to restart at a known good point before the
point of failure during the backup, select the Checkpoint enabled checkbox.
Configuring checkpoint restart backups on page 457 provides more information
on the requirements for checkpoint restart.
8. From the Directive list, select a directive to control how the NetWorker Server
processes files and directories during backup and recovery.
9. In the Save set box, type the name of the files or directories to back up, or click
the Browse button to browse and select file system objects.
Note: To avoid the over consumption of memory, NetWorker limits the
number of files that you can view when you browse a directory that contain
a large number of files, for example, 200,000 files. When NetWorker
determines that displaying the number of files will exhaust memory
resources, NetWorker will display a partial list of the files and a message
similar to the following appears: Expanding this directory has
stopped because the result has too many entries
When you manually specify the save set value, place multiple entries on
separate lines. For example, to back up a log file directory that is named
C:\log and all the data under the directory that is named D:\accounting,
type the following entries:
C:\log
D:\accounting
Follow the guidelines in the section "Mapped drives" to back up mapped drives
on Windows systems.
To back up all client data, type ALL. For Windows operating systems, the ALL
save set includes the DISASTER_RECOVERY:\ save set, which includes the
WINDOWS ROLES AND FEATURES save set.
NOTICE Some operating systems contain files and directories that should
not be backed up. Use directives to ensure that these files and directories
are not backed up.
Save sets on page 354 provides more information on defining the save sets for
a Client resource.
10. Select the other tabs in the Client Properties dialog box and configure options
as necessary.
11. Click OK.
Results
Verify that the client is enabled for scheduled backups by ensuring that a check mark
appears next to the client in the Scheduled backup column in the right pane for the
client.
Client priority
The Priority attribute on the Globals (1 of 2) tab of the Client Properties dialog box
for a Client resource enables you to control the order in which the NetWorker server
contacts clients for backup.
The attribute can contain a value between 1 and 1,000. The lower the value, the higher
the priority.
You must select View > Diagnostic Mode in the Administration interface to access the
Priority attribute in the Client Properties dialog box.
During a backup operation, the NetWorker server contacts the client with the lowest
priority value first. If you do not specify a priority for the Client resources, then the
backup order is random.
While the Priority attribute specifies the order of client contact, many variables affect
the order in which clients complete their backups. For example:
l The backup operation on a client does not begin until the worklists for each of the
save sets on the client are complete.
l The amount of work can vary greatly from one client to the next.
l If a client stops responding and times out, then the backup operation puts the
client backup at the end of the backup order list.
The only way to guarantee that the backup of one client occurs before the backup of
another client is to configure the data protection policies for the clients to start at
different times.
6. Click OK.
Manual backups
Manual backups enable users to make quick backups of a few files from the client
host.
When you perform a client-initiated or manual backup, by default NetWorker backs up
the data to a volume assigned to the Default pool on the NetWorker server. The
retention policy that is assigned to the data is one year, and the level is manual.
Perform manual backups on Windows by using the NetWorker User program. Perform
manual backups on UNIX and Linux only from the command line.
Note: You cannot perform data deduplication during backups with the NetWorker
User program. You must perform scheduled backups or manual backups from the
command line to perform data deduplication during the backup.
Procedure
1. In the NetWorker User program, click Backup.
The Backup window appears.
2. Select the data to back up.
To back up critical volumes, UEFI, the system reserved partition, and WINDOWS
ROLES AND FEATURES for disaster recovery purposes, select the
DISASTER_RECOVERY save set.
3. Click Start.
The Backup Status dialog box displays the progress of the backup. When the
backup finishes, a Backup completion time message appears.
If the backup fails due to a problem with VSS or a writer, an error message
appears. Use the Windows Event Viewer to examine the event logs for more
information. VSS backup error messages are also written to the NetWorker log
file.
The NetWorker log file in \install_path\logs\networkr.raw contains a
record of every file that was part of an attempted manual backup from the
NetWorker User program. This file is overwritten with the next manual backup.
To save the information in the file, rename the file or export the information by
using the nsr_render_log program.
NOTICE Certain types of corrupt files or errors on computer disk volumes
are not detected. NetWorker might back up this corrupt data. To avoid this
situation, run diagnostic programs regularly to correct disk volume errors.
If you do not specify the -s option with the save command, the files are backed up to
the NetWorker server that is alphabetically listed first in the /nsr/res/servers file
on the client computer.
UNIX man page and the NetWorker Command Reference Guide provides detailed
information about the save command.
BTRFS backups
NetWorker support BTRFS volume backups. When you specify a BTRFS volume or
sub-volume save set, NetWorker performs a recursive back up of the directory tree
that you specified with the save command. When NetWorker encounters a sub-
directory that has a sub-volume ID that differs from the parent sub-volume ID,
NetWorker will not back up the contents of the subdirectory, unless you specify the -x
option with the save command.
export CB_CACHE_LOCATION=cache_dir
export CB_LOG_DIR_LOCATION=log_dir
where:
l cache_dir is the directory that stores backup cache files.
l log_dir is the directory that stores for the backup log files.
Procedure
1. Log in as an administrator on the Windows client computer.
2. Open the NetWorker User program.
3. From the Operation menu, select Verify Files.
4. Select the data items to verify.
5. Click Start.
6. Monitor the data verification progress in the Verify Files Status dialog box.
After the verification is complete, the Verify Status dialog box shows any data
discrepancies.
Clone retention
NetWorker supports the ability to define a retention time for a clone save set that
differs from the original save set.
The following attributes determine the retention time that NetWorker assigns to the
original save set and clone save set.
l Retention policy attribute that is defined for the Client resource.
l Retention policy attribute that is defined for the Action resource that created the
save set.
l Retention policy attribute that is defined for the Pool resource that contains the
save set.
Note: This read-only attribute appears on the Configuration tab of the Pool
resource, when Diagnostic mode is enabled in the NetWorker
Administration window. This is a 8.2.x and earlier attribute, which you cannot
modify.
It is recommended that you define the retention policy for data in the Action resource.
If you define the retention policy for save sets in multiple resources, you might
experience unexpected save set expirations.
Cloning example
In this example, a backup of a client with three data drives creates three save sets.
These save sets are stored on a volume that is accessible through Storage Node A.
Once a cloning action occurs, the copies of these save sets are sent to eligible devices
in the clone pool on Storage Node B.
In this figure:
l A client performs a backup of three data drives to Storage Node A. NetWorker
creates three save sets, one save set for each data drive.
l A clone operation reads the data from the volumes on Storage Node A, and then
copies the save sets to Storage Node B.
Figure 47 Cloning example
n Data validation.
n Verification of the ability to read data from the media.
n Added protection of multiple copies across multiple volumes.
n De-multiplexing of multiplex backups for faster recovery.
Cloning with tape devices provides two benefits which should be considered for every
clone:
l Unlike disk-based devices, tape devices read data in a serial format. This means
that while multiplexing is beneficial from a backup streaming perspective, this is
not the case for recovery.
l If recovery speed is important, the use of clone copies as the source is likely to
result in faster recovery throughput.
Tape clone copies are often the preferred method to read data in a disaster recovery
situation. The ability to acquire, install, and configure a tape unit to read data is often
the first task on a disaster recovery plan.
By creating a copy of the backup on tape, you can eliminate the need for appliances
such as VTLs or disk systems to be in place. This often takes longer to acquire, install,
and configure. However, ensure that the tape copy is a full and complete copy,
without the dependence on other backups or deduplication appliances to complete the
restore operation.
Advantages
The advantages of cloning data to physical tapes include the following:
l Cloning can occur with the disk libraries under NetWorker control with standard
NetWorker policy support. You can use multiple retention policies for different
cloned copies of the data.
l Cloning can occur at the save set and volume level.
Note: NetWorker can clone a single save set, multiple save sets or all of the
save sets on a volume.
l Copying can occur from one tape type (virtual) to another tape type (target tape
library), also known as tape conversion.
l Copying can occur from multiple virtual tapes to a single tape, also known as tape
stacking.
Disadvantages
The disadvantages of cloning data to physical tapes include the following:
l Requires storage node licenses.
l Requires maintenance of front-end SAN infrastructure to a target tape library as
well as the virtual tape library.
l Consumes SAN bandwidth as data must be from virtual tape over the SAN to a
target device on the SAN.
media library. Select View > Diagnostic Mode in the Administration interface to
access the Recover storage nodes and Read Hostname attributes in the Client
Properties dialog box.
NOTICE If the clone source volume is on a remote storage node and is unmounted,
a volume clone operation cannot complete successfully, even if the source volume
is mounted after the clone operation tries to start. The nsrclone program is
unavailable with a message that the server is busy. This issue does not occur when
the storage node is on the NetWorker server (or, not remote) or when you
perform a clone controlled replication (optimized clone) operation.
Cloning operation logic for selecting a read source storage node
The cloning operation uses the following logic to determine the read source storage
node:
1. If the source volume is mounted, then the storage node of the device on which the
volume is mounted is used as the read source except in the following scenarios:
l If the FORCE_REC_AFFINITY environment variable is set to Yes.
l If the volume resides in a Virtual Tape Library (VTL) environment such as a
CLARiiON Disk Library (CDL).
In these scenarios, the NetWorker software ignores whether the source volume is
mounted and behaves as though the volume is not mounted.
2. If the source volume is not mounted or the FORCE_REC_AFFINITY environment
variable is set to Yes, then the NetWorker software creates a list of eligible
storage nodes, based on the storage nodes that meet both of the following
criteria:
l The storage node is listed in the Recover storage nodes attribute of the Client
resource for the NetWorker server.
If there are no storage nodes in the list and the Autoselect storage node
checkbox in the NetWorker server Client resource is clear, then the clone
operation uses the value in the Storage Nodes attribute for the NetWorker
server Client resource.
If there are no storage nodes in the list and the Autoselect storage node
checkbox in the NetWorker server Client resource is selected, then the clone
operation uses autoselect logic to choose the storage node.
l If the requested volume is in a media library, then the storage node is listed in
the Read Hostname attribute for the Library resource is used.
If the Read Hostname attribute for the Library resource is not set, then all
storage nodes on which any device in the library is configured are added to the
list of eligible storage nodes.
Note: If the volume is not in a media library, then the list of storage nodes is
based only on the criterion for storage node settings in the NetWorker
server Client resource.
Example
Consider the following example for a volume that resides in a media library and is not
mounted:
l The Recover storage nodes attribute in the NetWorker server Client resource
lists the following storage nodes in order:
n Storage node F
n Storage node E
n Storage node D
l The Read Hostname attribute for the Library resource is not set, but the following
devices in the media library are configured with storage nodes:
n Device A is configured on storage node D.
n Device B is configured on storage node E.
n Device C is configured on storage node B.
The list of eligible storage nodes is the intersection of the two previous lists (storage
nodes E and D). The order in which the storage node is selected depends on the order
of the storage nodes in the Recover storage node attribute list. In this example,
storage node E is selected first as the read source storage node. If storage node E is
not available, then storage node D is selected.
If no matching storage nodes are found in the intersecting list, then an error is written
to the daemon log file that indicates that no matching devices are available for the
operation. To correct the problem, ensure that at least one matching storage node
appears in both lists.
l If the checkbox is clear, then the clone operation uses the value in the Storage
Nodes attribute of the Client resource for the NetWorker server.
l If the checkbox is selected, then the clone operation uses autoselect logic to
choose the storage node.
You must select View > Diagnostic Mode in the Administration interface to access
the Autoselect storage node attribute in the Client Properties dialog box.
Note: If the volume is not in a media library, then the list of storage nodes is
based only on the criterion for storage node settings in the NetWorker
server Client resource.
l To create multiple clones. For example, clone 1 on disk, clone 2 to tape, each with
specific dependencies, timing, and logic.
Note: When using the scripted cloning feature, use the latest versions of
NetWorker software. This minimizes the complexity of the logic in the cloning
script.
The nsrclone command requires specific privileges which are assigned based on
session authentication. NetWorker supports two types of session authentication.
Token-based authentication, which requires you to run the nsrlogin before you run
the command and authenticates the user that runs the command against entries that
are defined in the External Roles attribute of a User Group resource. Classic
authentication, which is based on user and host information and uses the user
attribute of a User Group resource to authenticate a user. Classic authentication does
not require an authentication token to run the command. For example, if you run the
command without first running nsrlogin, NetWorker assigns the privileges to the
user based on the entries that are specified in the Users attribute of the User Group
resource. When you use nsrlogin to log in as a NetWorker Authentication Service
user, NetWorker assigns the privileges to the user based on the entries that are
specified in the External Roles attributes of the user Group resource. The NetWorker
Security Configuration Guide provides more information about privileges Using nsrlogin
for authentication and authorization provides more information.
l Combination of 2 options:
nsrclone -q "action=backup" -q "policy=Gold" -S -t "1 month ago"

User can add pre-existing group query options along with the newly added query
options . For example, -q group=<>
nsrclone -q "group=DPG" -q "action=backup" -q "policy=Gold" -q "workflow=NMC

The following table provides the descriptions of the options that are used in the
nsrclone command example.
Options Description
-S Specifies that the subsequent nsrclone
options are save set identifiers and not
volumes names.
Options Description
Updates to group, policy, workflow, and action fields in mediadb for a cloned
save set
When a cloned save set is queried for group, policy, workflow or action fields in
mediadb, output of the query can be categorized based on how cloning was carried
out (whether it was run through action or command line).
Action or policy clones- For concurrent, sequential, and scheduled clone types, the
cloned copy displays group, policy, workflow, and action for policy tree under which
clone action is created. For concurrent and sequential clones these fields are same as
backup copy.
Command line clones- Policy, workflow, and action fields are empty and only the
group which is inherited from backup is populated.
save sets from the primary data device ensures that there is always sufficient disk
space available on the primary device to store data.
To manage the staging process, manually stage individual save sets from a command
prompt or you can configure a Staging resource that automatically stages the data.
The Staging resource defines the criteria that the stage process uses to determine
when the data device requires data staging and which save sets are eligible to stage
and in what order.
Based on the configuration of the Staging resource, the staging process performs the
following high level activities:
1. Performs file system checks at an interval that is defined in the File system check
interval attribute to determine:
l If the percentage of used disk space on the source device exceeds the value
that is defined in the High water mark attribute of the Staging resource.
l If the length of time that the save sets have resided on the disk exceeds the
value that is defined in the Max storage period attribute of the Staging
resource.
2. Creates a list of save sets on the source device that are eligible to move to a
destination device.
3. Clones the eligible save sets from the source device to the destination device, and
then updates the media database with information about the save sets on the
destination device. The save set on the destination device retain the same
attributes values, for example retention policy, as the original save set.
4. Removes the original save sets from the source device, recovers disk space on the
source volume for staged save sets, and then removes information about the
original save sets from the media database.
Note: When the staging process encounters an error after successfully cloning
some save sets, the staging process only removes successfully staged save
sets from the source volume before the process ends. Only a single set of save
sets will exist on either the source or destination volumes after staging.
Staging data allows you to accommodate multiple service levels. You can configure a
staging policy that keep the most recent backups on one storage device for fast
recovery and move other backups with less demanding recovery requirements to more
cost-effective slower storage. For example, you can store the initial backup data on a
high performance file type or advanced file type device to reduce backup time. At a
later time, outside of the normal backup period, you use the staging process to move
the data to a less expensive but more permanent storage medium, such as magnetic
tape. After the backup data moves to the other storage medium, NetWorker deletes
the backup data from the file or advanced file type device so that sufficient disk space
is available for the next backup. Staging does not affect the retention policy of backup
data and the staged data is still available for recovery on the destination device.
You can stage a save set from one disk to another as many times as required. For
example, you could stage a save set from disk 1 to disk 2 to disk 3, and finally to a
remote tape device. When the save set is staged to a tape, it cannot be staged again.
However, you could still clone the tape.
The NetWorker Server Disaster Recovery and Availability Best Practices Guide describes
how to recover a bootstrap from the original disk.
Also, if the bootstrap data is not staged from the original disk, the data on the original
disk is subject to the same retention policies as any other save set backup and is,
therefore, deleted after the retention policy has expired.
9. In the Configuration group box, specify the criteria that starts the staging
policy.
The following table summarizes the available criteria that you can define for the
staging policy.
High water mark (%)—Defines the upper used disk space limit. When
the percentage of used disk space reaches the value that is defined in
the High water
mark (%) attribute, NetWorker starts the stage operation to move
save sets from the source disk.
Low water mark (%)—Defines the lower used disk space limit. When
the
percentage of used disk space reaches the value that is defined in the
Lower water mark (%) attribute, NetWorker stops moving save
sets from the source disk.
Save set selection Use this option to rank the order in which NetWorker stages the save
sets, based on save set size or age. Available values include:
l largest save set—Stage the save sets in order of largest save set
size to smallest save set size.
l oldest save set —Stage the save sets in order of oldest save set
to most recent save set.
l smallest save set—Stage the save sets in order of smallest save
set size to largest save set size.
l youngest save set—Stage the save sets in order of most recent
save set to least recent save set.
Max storage period Use this option to start the stage operation based on the amount of
time that a save set has resided on the volume.
Max storage period
unit l Max storage period—Defines the number of hours or days that a
save set can reside on a volume before the stage process considers
the save eligible to move to a different volume.
l Max storage period unit—Defines the unit of measurement for
the value in the max storage period attribute. Available values are
Hours and Days.
The maximum storage period setting is used along with the file system
check interval. Once the maximum storage period is reached, staging
does not begin until the next file system check.
Recover space Use this option to determine when the stage operation removes the
interval successfully staged save set from the source volume.
File system check Use this option to define when NetWorker automatically starts the
interval staging process.
l File System Check Interval—Defines the frequency in which
NetWorker starts the staging process. At every file system check
interval, if either the high water mark or the maximum storage
period has been reached, then staging begins.
l File system check unit—Defines the unit of measurement for the
value in the file system check interval attribute. Available values are
Hours and Days.
authentication, which is based on user and host information and uses the user
attribute of a User Group resource to authenticate a user. Classic authentication does
not require an authentication token to run the command. For example, if you run the
command without first running nsrlogin, NetWorker assigns the privileges to the
user based on the entries that are specified in the Users attribute of the User Group
resource. When you use nsrlogin to log in as a NetWorker Authentication Service
user, NetWorker assigns the privileges to the user based on the entries that are
specified in the External Roles attributes of the user Group resource. The NetWorker
Security Configuration Guide provides more information about privileges, and Using
nsrlogin for authentication and authorization provides more information.
3. Use the nsrstage command to migrate the save sets to another volume.
For example:
nsrstage -m -S ssid/cloneid
Note: When you do not use the -b option to specify a destination clone
pool, the nsrstage command migrates the save sets to a volume in the
Default Clone pool.
UNIX man page and the NetWorker Command Reference Guide provides detailed
information about the nsrstage and mminfo commands.
How to remove incomplete or aborted save sets that the staging process does
not migrate
The stage operation does not move aborted or incomplete save sets to a tape device.
To remove the save sets from the source device, perform the following steps:
1. Manually delete the save set from the media database by typing: nsrmm -d -S
ssid
2. Remove the save sets from the source device by typing: nsrstage -C -V volume
How to resolve the 'nsrstage: device `(staging_volume)' is not enabled' error
Staging fails with this error when either the source or destination device is not ready.
The following error message might also appear:
Error: 'nsrd: media warning: (staging_volume) reading: Badfile
number'
When you see these errors, ensure the following:
l The source device is not in service mode.
l The destination tape device or jukebox is properly synchronized.
Archiving data
The archive process captures files or directories as they exist at a specific time, and
writes the data to archive storage volumes, which are not automatically recycled.
After the archive process completes, you can delete (groom) the original files from
the disk to conserve space.
The client archive program (nsrarchive) creates an archive. The client nsrexecd
service starts this archive.
The following figure illustrates how the NetWorker software archives data.
where:
1. Client file systems
2. Backup data tracking structures
3. Data
4. Media database information
5. File index information
Archive save sets
Archive save sets are similar to backup save sets. The main difference is that there is
no retention period for archive save sets, so the archive save sets never expire.
By default, the archive backup level is always set to full.
Licensing
You must purchase and license the archive feature separately from other NetWorker
software components. The NetWorker Licensing Guide provides more information on
licensing procedures.
Encryption of archive data
If the NetWorker client is set up for encryption with the aes ASM, then archive data is
also encrypted.
Limitations
The following limitations apply to the archive feature:
l You cannot archive the WINDOWS ROLES AND FEATURES save set.
l The Client Direct feature does not support archiving.
Information about archive data is tracked in the media database for the NetWorker
server.
Configuring pools to index archive data
The settings for the archive pool that is used to store archive data determine whether
you index archive data.
When you index archive data, information about individual files in the archive save set
is tracked in the client file index. The client file index entries that are generated during
an archive are backed up to volumes from the default pool during the next scheduled
backup. You can browse and recover individual files from indexed archive save sets.
However, indexed archive data can result in a large client file index that never expires.
When you perform nonindexed archiving, entries are not added to the client file index.
You must recover the entire save set instead of browsing to and recovering individual
files.
Default archive pools
The following default pools are available for archived data:
l Indexed Archive pool
l PC Archive pool
l Archive pool
The Indexed Archive pool and the PC Archive pool support indexed archiving. The
Archive pool supports nonindexed archiving.
You cannot change the settings for these default pools, although you can create
custom archive pools.
If you do not specify a pool to store archived data, the NetWorker software uses the
Indexed Archive pool by default.
Custom archive pools
You can create custom archive pools in the Media window of the Administration
interface. The Store index entries checkbox on the Configuration tab for the media
pool determines whether the archive data written to the volumes in the pool are
indexed. Select the checkbox to perform indexed archiving, or clear the checkbox to
perform nonindexed archiving.
Enabling archiving
After you license the archive service and type the enabler code in the NetWorker
server, all clients for that server are enabled for the NetWorker archive feature by
default. You can specify which clients and users have permission to archive data.
Before you begin
Ensure that the NetWorker Server is in diagnostic mode. To enable diagnostic mode,
from the View menu, select Diagnostic mode.
Procedure
1. To control whether a client can archive data, in the Client Properties window,
on the Globals (2 of 2) tab, perform one of the following actions on the
Archive services box.
l Clear the checkbox to disable archiving for the client.
l Select the checkbox to enable archiving for the client.
You must select or clear the Archive services checkbox for all Client resources
that are associated with the client. You might have multiple Client resources for
a single client. For example, if both the NetWorker module software and the
NetWorker client software are installed on the same computer, there are
multiple Client resources.
2. Add users that should have permission to perform archiving to the Archive
Users user group in the Server window of the Administration interface.
The NetWorker Security Configuration Guide provides details.
Performing a save set recover with NetWorker User on page 566 provides details on
save set recovery.
Procedure
1. Mount the archive volume in the storage device.
2. In the NetWorker User program, select Operation > Archive Retrieve.
The Source Client dialog box appears.
3. Select the source client with the data to recover, and click OK.
The Archive Retrieve dialog box appears.
4. In the Annotation string box, type all or part of the annotation string that you
specified for the save set when it was archived.
Leave the box empty to view a list of all archived save sets for the client.
5. Click OK.
The Save Sets dialog box appears.
6. To view a list of volumes that are required to retrieve the data from this
archived save set, click Required Volumes.
7. To type a new path for the location of the recovered data and to indicate what
the NetWorker server should do when it encounters duplicate files, click
Recover Options.
8. Select the archived save set to recover and click OK.
The Retrieve Status dialog box displays the status of the recovery.
where:
l NetWorker_server is the hostname of the NetWorker server.
l -A annotation specifies the annotation string for the archive save set. You
must specify at least one annotation or save set ID.
Consider an example where archive A is annotated with Accounting_Fed
and archive B is annotated with Accounting_Local. If you type
nsrretrieve -A Accounting, then no match is found and the archive data
is not recovered. If you type nsrretrieve -A ting_L, then the recovery
process recovers the data from Archive B.
l -S ssid/cloneid specifies the archive save set to recover. To recover a
cloned archive save set, specify both the save set ID and the clone ID. You
must specify at least one annotation or save set ID.
Archive request succeeds but generates error when nsrexecd is not running
If the nsrexecd process is not running on a remote client during an archive request
operation, NetWorker reports that the archive operations completed successfully, but
the following error message appears in the daemon.raw file and the archive fails:
To resolve this issue, ensure that you start the nsrexecd daemon on a UNIX client or
the NetWorker Remote Exec service on a Windows client before you perform an
archive operation.

Managing volumes
A volume is a physical piece of media such as a tape cartridge or disk. On file type
devices, a volume is a directory on a file system. Volume management tasks include
changing the mode or recycle policy for the volume, relabeling the volume, removing
volumes from the media database and online indexes, and marking a volume as full for
offsite storage.
If a volume is not mounted when a backup is started, then one of three messages
appears, suggesting that one of these tasks be performed:
l Mount a volume.
l Relabel a volume (only when Auto Media Management is enabled).
l Label a new volume (only when Auto Media Management is enabled).
During file recovery, the NetWorker server requests the volume name. If multiple
volumes are needed to recover the files, the server lists all the volumes in the order of
which they are needed. During the recovery process, the server requests each volume,
one at a time. If a library is used, the server automatically mounts volumes that are
stored in the library.
To manage volumes, you must have the correct permissions that are associated with
the NetWorker server and its storage nodes.
all exceeded their retention periods. Appendable volumes can receive additional
backup data.
Procedure
1. Unmount the volume by right-clicking the device in the Devices window and
selecting Unmount.
2. In the Administration window, click Media.
3. In the left pane, select either Disk Volumes or Tape Volumes.
A list of volumes appears in the right pane.
4. Right-click the volume and select Change Mode.
The Change Mode dialog box appears.
5. Select a mode and click OK.
The new volume mode appears in the Mode column.
6. (Optional) Mount the volume by right-clicking the device in the Devices
window, and selecting Mount.
the volume changes to recyclable. You can relabel and overwrite a recyclable
volume to reclaim backup storage.
l AFTD or Data Domain devices—Entries for save sets that are marked browsable
are removed from the client file index and media database. Entries that are
recoverable are removed from the media database. The expire action removes the
data that are associated with the save sets from the disk volume and reclaims the
disk space.
The NetWorker server maintains one file index for each client computer (regardless of
the number of client resources for the client), and one media database that tracks
data from all clients and all save sets.
Note: For AFTD devices, there might be some instances where the save sets are
not removed. This might happen, if you have any incremental or level backup
dependency with previous backups. The save sets are removed only after all the
dependent incremental or level backup gets into the recyclable mode.
Recovering data
You can recover NetWorker data by using the recover command, the NetWorker
User program on Windows, or the NMC Recovery wizard on the NMC server.
Recovery roadmap
The following figure provides a high-level roadmap of the recovery paths for a
NetWorker Client and Storage Node host.
Figure 51 Recovery roadmap
Hardware information
Maintain up-to-date information on computer hardware as follows:
l File system configuration
l Fully qualified domain names, IP addresses, and hostnames
l For Domain Name System (DNS) clients, maintain the DNS host's internet address
and hostname
l Hard drive configuration
l Media device names
l Hardware vendor
l Configuration information for each piece of hardware, both active and inactive,
within the organization or organizational site
Software information
Maintain up-to-date information on computer software as follows:
l Copies of the original operating system media and patches (and where they are
located)
l Software enabler and authorization codes
l Software vendor contact information and contract number
l The operating system version and patches installed
l Operating system configuration
l Emergency media that can be used to recover a computer if a disaster occurs
l NetWorker bootstrap information for each NetWorker server
l Kernel configuration and location
l Device drivers
l List of any volume mount points
Note: To upgrade the storage node software, first recover the storage node
to its original state and then perform the upgrade.
2. Reinstall any NetWorker backup patches that were installed before the disaster.
3. Re-create any links to NetWorker directories.
4. (Optional) To perform a test recovery to ensure that the recovery process is
functioning correctly, use the recover command.
Note: The NetWorker client software is also installed when you install the
storage node software.
Results
The storage node can now access volumes that contain backups for other computers
on the network. These volumes contain the application and user data that are required
to recover computers that were protected with the NetWorker client software.
l Destination host—The NetWorker host that receives the recover data. The
destination host can be the source host or another NetWorker host in the
datazone.
Recovery types
NetWorker provides you with two types of recoveries.
l Local recover—A single NetWorker host is the administering, source, and
destination host.
l Directed recover—The administering host is the source host or any other
NetWorker host in the datazone. The destination host is not the source host. Use
a directed recovery:
n To centralize the administration of data recoveries from a single host.
n To recover the data to a shared server, when the user cannot recover the data
themselves.
n To recover data to another host because the source host is inoperable or the
network does not recognize the source host.
n To transfer files between two NetWorker hosts.
Directed recoveries
A directed recovery enables a user to recover data to a NetWorker host that differs
from the source of the backup, while retaining the original file ownership and
permissions.
A directed recovery is a restricted NetWorker function available only to user accounts
that have the necessary privileges that are required to perform the directed recovery
operation.
A user with directed recovery privileges can:
l Browse the backup data of all NetWorker clients.
l Recover the data to any NetWorker client.
The following figure provides an example of a directed recovery.
In this figure:
l Saturn is the administering host.
l Neptune is the NetWorker server.
l Mars is the destination host.
l Pluto is the source host (not shown).
l The OS of destination host is the same as a source host.
Host Requirements
Destination Ensure that the destination host:
l Is the same platform as the source host, for example, Linux to Linux, AIX to AIX, or
Windows to Windows.
l Uses the same file system as the source host, for example, XFS to XFS, UFS to UFS,
or NTFS to NTFS.
l Contains an entry for the administering host in the servers file. The NetWorker
Security Configuration Guide provides more information about client-tasking rights and
how to modify the servers file.
l Is configured to accept directed recoveries from a remote host. Ensure that the
Disable Directed Recover attribute is set to the default value No, in the NSRLA
Host Requirements
database. Editing a client NSRLA database on page 823 describes how to edit the
NSRLA database.
l Has the required access rights to receive data.
n If you run the nsrlogin command on the administering host to create an
authenticated recover session, ensure that the External Roles attribute of a user
group with Remote Access All Clients privileges contains one of the following
entries:
Administrator@venus
Administrator@venus
Host Requirements
Administering Ensure that the administering host:
l Is a client of the NetWorker server that contains the backup information. The
administering client can be a different platform from the source and destination
clients.
l Has the required access rights to perform the recover operation.
n If you run the nsrlogin command on the administering host to create an
authenticated recover session, ensure that the External Roles attribute of the
Operators, the Application Administrators, the Database Administrators, or the
Database Operators user group contains one of the following entries:
Windows requirements
NetWorker enables you to perform directed recoveries of data to a local drive on
Windows destination host, when you enable Windows File and Print Sharing option on
the destination host . You cannot perform a directed recovery to a CIFS share.
When you use the recover command on a Windows destination host and the
NetWorker server is also a Windows host, change the account that starts the
NetWorker Backup and Recovery service on the NetWorker server:
l When the NetWorker server and the destination host are in the same domain, start
service with a domain user that is a member of the local Administrators group.
l When the NetWorker server and destination host are not in a domain, or are not in
the same domain, start the service with a local user that meets the following
requirements:
n The same username exists as a local user on the destination host.
n The local user must have the same password on both hosts.
n The local user on the NetWorker server is a member of the local Administrators
group.
Local recoveries
When you perform a local recovery, the administering host is also the source and
destination host. Local recoveries are the simplest way to recover NetWorker data.
Ensure that user account that performs the recovery operation meets the following
requirements:
l Belong to a NetWorker User Group that has the Recover Local Data privilege.
If you use nsrlogin, add the DN or the user or group to the External Roles. If you do
not use nsrlogin, add the account in user@host to the Users attribute. The
NetWorker Security Configuration Guide provides more information.
l Have operating system ownership of the recovered files. The root user on UNIX,
and a Windows Administrator have this privilege.
l Have write privileges to the local destination directories. The root user on UNIX,
and a Windows Administrator have this privilege.
Recover programs
NetWorker provides you with the following tools to recover data.
l NetWorker Recover program—Recover GUI for OS-X hosts.
l NMC Recovery wizard—Recover wizard that you start from the NMC server. The
NMC Recovery wizard provides a NetWorker datazone with a centralized
recovery method.
l The recover command—CLI tool available on Windows, UNIX, and OS-X. Use
the recover command to recover data from a command prompt. To perform
multiple recovery operations in parallel, use multiple recover commands.
l NetWorker User program—Recover GUI for Windows hosts. Use the NetWorker
User program to recover file system data when the administering client is
Windows.
l The scanner command—CLI tool available on Windows, UNIX, and OS-X. Use
the scanner command to recover data from a volume by save set ID (SSID) to
the host that starts the program. To perform multiple recovery operations in
parallel, use multiple scanner commands.
Note: The NetWorker User, NetWorker Recover, and NMC Recovery wizard
programs only recover data sequentially.
l Output sent to stderr and stdout in a recover log file. NetWorker creates one log
file for each recover job. Troubleshooting the Recovery Wizard on page 547
provides more information.
NOTICE NetWorker removes the recover log file and the job information from
the job database based on value of the Jobsdb retention in hours attribute in
the properties of the NetWorker server resource. In NetWorker 9.0.1, the
default jobsdb retention is 72 hours.
b. Display the attributes for the Recover resource that you want to
troubleshoot. For example:
c. Make note of the values in the recover, recovery options, and recover
stdin attributes. For example:
</recoverpath>
</xml>”;
where:
l nw_server.corp.com is the name of the NetWorker server.
l mnd.corp.com is the name of the source NetWorker client.
3. To confirm that the nsrd process can schedule the recover job:
a. To start the recover job, update the Recover resource:
5. When the nsrtask command completes, review the nsrtask output for errors.
6. To confirm that the Recovery UI sends the correct recovery arguments to the
recover process:
a. Open a command prompt on the destination client.
b. Run the recover command with the recover options that the Recover
resource uses. For example:
c. At the Recover prompt, specify the value in the recover stdin attribute.
Note: Do not include the “ ,”, or the ; that appears with the recover
stdin attribute.
b. To set the query to a particular jobid and display the results of the job, type:
print job id: jobid
Where jobid is the jobid of the Recover job that you want to review.
Note: Review the daemon.raw file on the NetWorker server to obtain
the jobid for the recovery operation.
Scanner recovery
The scanner program enables you to recover data directly from a NetWorker volume.
Use the scanner program in the following scenarios:
l To perform a by-file-selection recovery, when the save set information is not in
the client file index.
l To recover data directly from a tape.
l To recover data from an incomplete save set.
NetWorker User program You can select the volume when you perform
a save set recovery.
When NetWorker selects the volume from which to recover data, the recovery
operation uses the following logic:
1. The highest priority is assigned to the volume (clone or original volume) that has a
complete, non-suspect save set status. A complete save set that is suspect has a
higher priority than an incomplete non-suspect save set.
2. If the volumes still have equal priority, then priority is assigned to the mounted
volume.
3. If the volumes are mounted, then priority is based on the media type. The media
types from highest to lowest priority are:
l Advanced file type device
l File type device
l Other (such as tape or optical)
4. If the volumes are not mounted, then priority is based on the media location. The
media locations from highest to lowest priority are:
l Volumes in a library.
l Volumes that are not in a library but are onsite (or, the offsite flag is not
set).
l Volumes that are offsite (or, the offsite flag is set).
To specify that a volume is offsite, use the nsrmm command. For example:
Procedure
1. On the Administration window, click Server.
2. In the left pane of the Server window, right-click the NetWorker server.
3. From the File menu, select Properties.
4. Select the Configuration tab.
5. In the Recover section, select ACL passthrough.
Browsable recovery
A file selection recovery method, or browsable recovery inspects the client file index
that NetWorker creates for the source host, to gather information about backups.
When the recovery process reviews entries in the client file index, you can browse the
backup data and select the files and directories to recover. The retention policy that
NetWorker applies to a backup determines the earliest versions of files and file
systems that are available for recovery. Backup retention on page 378 provides more
information about browse and retention policies.
Use a browsable recovery in the following scenarios:
l To recover a file or directory when you are not certain of its exact name or
location.
l To recover a small number of files or directories. When you select many files and
directories, the process of marking the files for recovery and the recovery process
can take some time to complete, particularly from the NetWorker User program.
l To perform a directed recovery.
l To recover only the files that you select in one or more directories, not all files in a
directory.
Adding information about recyclable save sets to the client file index
Each NetWorker client, including the NetWorker server, has a client file index (CFI).
The CFI is a database that contains information about the files that are in a save set.
When NetWorker adds save set information into the media database and CFI,
NetWorker assigns the save set a retention date, which is based on the retention
policy that is assigned to the backup, clone, or archive. Browsable information about
the save set remains in the CFI until the current date is equal to the retention date.
When the current date is equal to the retention date, NetWorker expires the save set
and identifies the save set as no longer required for recovery, or as eligible for
recycling. When the status of the save set is eligible for recycling, NetWorker removes
the information about the save set from the CFI, and you cannot perform a browsable
recovery of the save set data. Some applications, such as the NetWorker Module for
Databases and Applications, require that a save set is browsable to perform a
recovery.
You can make expired save set files browsable for recovery by adding the save set
information back into the client file index.

Recoverable Information about the save set Information appears only in the media
database. NetWorker does not allow information about some save sets, for
example the bootstrap save set to appear in the CFI for browsing.
Recyclable The save set has expired is eligible for recycling. The save set has exceeded
the defined retention policy.
Incomplete The save set did not complete. NetWorker does not store save set
information about an incomplete save set in a CFI.
where:
l MM/DD/YYYY is the date that is chosen to make the save set browsable
from.
l ssid/cloneid is the save set ID/cloneid.
For example:
When more than one SSID was recorded, repeat this step for all SSIDs.
When more than one SSID was recorded, repeat this step for all SSIDs.
When more than one SSID was recorded, repeat this step for all SSIDs.
2. Query the media database to confirm that the index save set for a client is
recoverable:
where client_name is the name of the client to which this save set is located.
3. Confirm that the value in the fl column is cr for an index backup with the time
frame of the client save set to be restored.
NOTICE If the index save set is not recoverable, the save set expires when
the NetWorker software cross checks the indexes. For example, when the
NetWorker server runs the nsrim -X command.
where ssid is the associated save set id for the data you want to recover.
3. Use the information from the mminfo command for the save set to run the
scanner program. When the save set spans more than one volume, scan the
volumes in the order in which in which they were written:
where:
l mediafile is the starting file number for the save set, obtained from the
mminfo output.
l mediarec is the starting record number for the save set, obtained from the
mminfo output.
l device is the name of the device the volume is loaded in, for example /dev/
rmt0.1 or \\.\Tape0.
4. When the save set spans multiple volumes, the scanner program prompts for a
new volume as needed.
Repopulating the client file index by using the nsrck program
Use the nsrck program to repopulate the client file index with information about all
save sets for the client up to the date and time specified.
Procedure
1. Ensure that the volume containing the index backup is available.
2. Use the nsrck command to repopulate the client file index:
nsrck -L 7 -t MM/DD/YYYY client_name
where:
l where client_name is the name of the client with the data to be recovered.
l MM/DD/YYYY is the backup date of the save set.
For example:
<NetWorker_install_path>\nsr\bin>nsrck -L 7 -t
"11/21/2009" swift nsrck: checking index for 'swift'
9343:nsrck: The file index for client 'swift' will be
recovered.Requesting 1 rec over session(s) from server
Recover completion time: 11/20/2009 1:45:55 PM nsrck:
<NetWorker_install_path>\nsr\index\swift contains 12
records occupying 2 KB nsrck: Completed checking 1
client(s)
When you recover a client file index from a time and date in the past, nsrck
adds the full contents of the index from that time and date to a temporary
subdirectory of the client file index directory. When a time value is not
specified, everything for the specified date (up to 23:59) is included. After the
index has been read from the backup media, the required index data is
integrated fully into the client file indexes and the temporary subdirectory is
removed. The “required index data” includes the indexes from the date
specified to the first full backup that occurred prior to the date specified.
Be aware that if a save set from the specified date runs into the next day, which
would be Nov 22, 2009 in this example, then the index required to browse the
save set will not be recovered. To recover this index, you would have to specify
Nov 22, 2009 as the recovery date as shown in the following command:
nsrck -t "11/22/2009" -L7 swift
A check on the required index date may be necessary if index backups are set to
be taken once daily. When the back up of the index does not take place until the
following day, the date of the following day must be specified.
3. Confirm that the client save sets are now browsable:
NetWorker_install_path\nsr\bin>mminfo -q ssid=4294078835 -r

Adding information about a save set in the client file index and media database
When a volume contains a save set that does not appear in the media database or
client file index, use the scanner command to restore save set information into the
media database and client file indexes.
About this task
Procedure
1. Log in as root or a Windows Administrator.
2. Load the first volume that contains the save set information into an available
device. Ensure the Idle Device Timeout value for the device is 0. Refer to
Unmounting volumes automatically (idle device timeout) on page 155 for details.
3. At the command prompt, run the scanner and specify the name of the device
that contains the volume:
scanner device_name
l To repopulate media database and CFIs with the save set information for all
save sets on the volume, type scanner -i device_name
l To repopulate the media database and client file index with the save set
information for a specific save set , type scanner -i -S ssid
device_name
NOTICE When the volume contains data from an earlier version of
NetWorker, there may be no pool information on the volume. In this
case, the volume is considered to belong to the Default pool. To assign
the volume to another pool, use the -b pool_name option in this step.
When the volume already belongs to a pool, the -b option will have no
effect.
7. Select optional recover options. The following table summarizes the available
recovery options.

2. Ensure that the volume which contains the save set is available for a device in
the datazone.
3. Use the recover command to select and then to recover the data from the
backup save set or the clone save set.
For example, type:
where:
l date is the date that NetWorker created the save set.
Note: When you do not specify a date, the recover command displays
the latest version of each file in the save set.
l source_host is the original data host.
Note: When you do not specify source host, NetWorker assumes that
the source client is the host where you run the recover program.
l destination_host is the host on which to recover the data.
l pool_name is the name of the pool that contains the volume. Use this option
when you want to recover data from a clone volume.
l - i_recover_option specifies how NetWorker handles a naming conflict
between a recovered file and an existing file.
n iN does not recover the file when a conflict occurs.
n iY overwrites the existing file when a conflict occurs.
n iR renames the file when a conflict occurs. The recover process appends
a .R to each recovered file name.
Note: The recover command requires the -i option when you use the
-R option to perform a directed recovery.
For example, to recover the data from a clone volume from a clone operation
that was performed on July 20, 2015, type:
c. To view the files or directory that you marked for recovery, type:
recover> list
d. To view the list of the volumes that NetWorker requires to recover the data,
type:
recover> volumes
e. To recover the files to a location that differs from the original location, type:
recover> relocate path
l To recover many files or all the data in a save set, for example, if there is a total
disk failure. When you perform a save set recovery, you do not select individual
files or directories for recovery.
l To recover data from a recyclable save set. Backup retention on page 378 provides
more information about browse and retention policies. Adding information about
recyclable save sets to the client file index on page 553 describes how to
repopulate the client file index entries for recyclable (expired) save sets.
l To recover data on a host with limited memory resources. A save set recovery
requires less memory than a browsable recovery.
Click OK.
Relocate the recovered file system objects By default, NetWorker recovers file system
objects to their original location. To relocate
the files to a different location:Select
Recover Options.
8. Click OK to begin the recovery. The NetWorker server takes a few moments to
start the file recovery, depending on file size, network traffic, server load, and
tape positioning. When NetWorker starts to recover the files, messages appear
that enable you to monitor the progress of the recovery.
When the recovery is successful, a message similar to the following appears:

user, NetWorker assigns the privileges to the user based on the entries that are
specified in the External Roles attributes of the user Group resource. The NetWorker
Security Configuration Guide provides more information about privileges
Procedure
1. Connect to the target host with the root account on UNIX or the Administrator
on Windows.
2. Use the mminfo command to display information about the save set of the data
that you want to recover.
For example, type: mminfo -av -r
volume,savetime,client,ssid,cloneid,name
Output similar to the following appears:
The mminfo command provides you with information that you require to
recover the save set. For example, the name of the volume that contains the
save set and the date that the save set was created. NetWorker assigns each
backup and clone save set the same save set ID (SSID) and unique clone ID
(cloneid).
3. Ensure that the volume which contains the save set is available for a device in
the datazone.
4. Use the recover command to recover the data from the backup save set or
the clone save set.
Note: To perform concurrent recoveries from an advanced file type by
either using multiple -S options to identify multiple save sets, or starting
multiple recover commands.
l To recover the all the data from a backup save set, type the following
command:
where:
n ssid is the SSID of the backup save set.
n - i_recover_option specifies how NetWorker handles a naming
conflict between a recovered file and an existing file.
– iN does not recover the file when a conflict occurs.
– iY overwrites the existing file when a conflict occurs.
– iR renames the file when a conflict occurs. The recover process
appends a .R to each recovered file name.
For example:
l To recover the all the data from a clone save set, type the following
command:
recover -S ssid/cloneid
where:
n ssid is the SSID of the backup save set.
n clonied is the cloneid of the clone save set.
For example:
recover -S 3644194209/1362493448
Note: When you do not specify the cloneid of the save set, the recover
command recovers the data from the backup save set.
l To recover a single directory from the clone save set and relocate the data
to a new directory location, type the following command:
where:
n ssid is the SSID of the backup save set.
n cloneid is the cloneid of the clone save set.
n destination_dir is the location to which you want to recover the data.
n original_dir is the directory that is contained in the save set that you
want to recover.
For example, to recover the directory /var/adm on the backup save set to
the /usr/mnd directory, type the following command:
recover -S 3644194209/1362493448 -d /usr/mnd /var/adm
l To recover data that was encrypted with the current AES pass phrase, no
special action is required. However, to recover data that was encrypted with
an AES pass phrase that is different than the current pass phrase,start the
recover command specify the -p pass_phrase. To enter multiple pass
phrases with the -p option, type: recover -p pass_phrase1 -p
pass_phrase2 -p pass_phrase3.
NOTICE When an incorrect pass phrase or no pass phrase is entered,
encrypted data is not recovered. Instead, the file names are created
without data. However, if unencrypted data is also selected for
recovery, it is recovered.
not require an authentication token to run the command. For example, if you run the
command without first running nsrlogin, NetWorker assigns the privileges to the
user based on the entries that are specified in the Users attribute of the User Group
resource. When you use nsrlogin to log in as a NetWorker Authentication Service
user, NetWorker assigns the privileges to the user based on the entries that are
specified in the External Roles attributes of the user Group resource. The NetWorker
Security Configuration Guide provides more information about privileges

renamed ~00_file_name, and so forth, to ~99_file_name. When this fails,
the recover process does not automatically rename the file and prompts
the user is to specify a name for the file.
n Discard recovered file— Discards the recovered file and keeps the
existing file.
n Replace local file— Replaces the file on the file system with the
recovered version.
3. On the new NetWorker server, create each Pool resource that was used to
write the client data on the original NetWorker server.
Note: Ensure that you create each Pool resource with the same name that
you used on the original NetWorker server.
4. Use the scanner command to import the save set information into the new
NetWorker server.
l To import the save set information into the client file index and media
database entries, type the following command:
where client_name is the name of the client that appears on the original
NetWorker server.
l To import the save set information into the media database only, type the
following command: scanner -m -c client_name device_name
where client_name is the name of the client that appears on the original
NetWorker server.
NOTICE When you use the scanner -i or scanner -m to import data

l Only the media database contains the client ID and save set information
for the imported save sets.
l If the same hostname already exists on the NetWorker server,
NetWorker will not use the original hostname to store the save set
information because the client ID is different. NetWorker associates the
save set information with a hostname in the format clientname-#.
l You must create a Client resource with the name clientname-# and
specify the client ID that you recorded from the original NetWorker
server.
l Optionally, after you create the new Client resource, run the scanner
-i command to store the save set information into the client file index.
When you use the scanner command, specify the client name as it
appears on the original NetWorker server.

Non-authoritative restore
A non-authoritative restore returns the domain controller to its state at the time of
backup, then allows normal replication to overwrite that state with any changes that
have occurred after the backup completed.
After restoring the system state, the domain controller queries its replication partners.
The replication partners replicate any changes to the restored domain controller,
ensuring that the domain controller has an accurate and updated copy of the AD
database.
Non-authoritative restore is the default method for restoring AD. This method is used
in most situations that result from AD data loss or corruption.
Authoritative restore
An authoritative restore is an extension of the non-authoritative restore process that
allows an administrator to recover a domain controller to a specific point in time and
mark objects in the AD as authoritative. After you recover objects that are marked
authoritative the objects are replicated to all the other domain controllers in the
domain. Before you perform an authoritative restore, you must complete the steps for
a non-authoritative restore.
3. When the restore completes, verify that the operation was successful.
4. To complete the AD restore, restart the domain controller.

b. Browse to the location that contains the disk driver, and then load the
required disk driver.
c. To update the list of detected disks, select Refresh.
d. Click Next.
7. On the Select NetWorker Server screen, complete the fields:
a. In the Server field, specify the NetWorker server that performed the
backup:
l Select the NetWorker server from the server list. To update the list of
NetWorker servers, click Search. The Search function locates only those
NetWorker servers on the local subnet.
l Type the fully qualified domain name (FQDN).
b. In the Client field, ensure that the client name matches the Client resource
name on the NetWorker server.
NetWorker automatically populates this field with the values that you
specified in the Hostname and DNS Domain fields on the Configure
Hostname and Network screen of the wizard. For example, if the client
resource on the NetWorker server uses an FQDN, then specify the FQDN of
the client in the Client field.
To recover the backup to a host that differs from the source host, modify
the Client field to specify the target hostname.
If you specify a different client, the recovered host uses the same hostname
and IP settings as the source computer. If the source computer is running on
the same network, using the same hostname and IP settings can cause
hostname and IP address conflicts.
c. Click Next.
8. On the Select Bare Metal Recovery Backup screen, select the system backup
that you want to recover, and then click Next.
System backups appear in descending order from most recent to oldest.
9. Review the Save Sets to Restore screen, and then click Next.
The recovery process reformats critical volumes. The recovery process
reformats non-critical volumes only if the disk signature on the target disk
differs from the original disk.
For example, to perform a quick format instead of a full format operation if the
disk was replaced, select Perform a quick format of disks.
Note: A quick format is much faster than full format but does not verify
each sector on the volume.
The recovery process does not recover non-critical volume data. Recovering file
system data provides more information.
10. On the Bare Metal Recovery Summary screen, select Options to display the
Non-Default Recover Options screen.
11. On the Non-Default Recover Options screen:
a. In the Additional Options field, type any required non-default options with
their corresponding values.
Non-default options are primarily used for troubleshooting purposes.
b. To save and close the Non-Default Recover Options screen, and then
return to the Bare Metal Recovery Summary screen, click OK.
c. To begin the recovery process, click Restore.
12. On the Confirmation screen, select the I confirm that I want to format the
disks and restore the backup option, and then click OK.
NOTICE All data is lost on all volumes that the recovery process reformats.
After the data recovery completes, the wizard writes the recovery log files to
volumes in the backup media pool being used. If you do not have a volume
available, then the recovery operation appears to be unavailable until media for
the media pool becomes available.
Note: You can cancel the log file backup without affecting the recovery
operation.
13. After the wizard and log files complete, click either Reboot or Exit:
l To restart the system when any subsequent application data resources must
be performed, click Reboot. If you are recovering an Active Directory
domain controller, it is recovered in non-authoritative mode by default.
l If you must recover a domain controller in authoritative mode, click Exit. The
computer returns to the WinPE command prompt. Start into Directory
Services Restore Mode (DSRM). See Performing post recovery tasks for
active directory services for more information.
Post-recovery tasks
The following sections provide information about recovering data that was not
recovered in the Windows BMR operation.
Using NMM for post-recovery tasks
If the recovered host has applications that are protected with NMM, all application-
recovery operations must be performed by using the NMM client interface. The NMM
documentation provides information on the post-recovery operations.
About this task
Before reviewing the NMM documentation, review the following information:
l After the recovery has completed and the system is rebooted, check the host’s
disk and volume configuration. All disks and volumes should appear as they did on
the original system. However, if disk signatures do not match the original disks,
non-critical disks might be offline or unmounted. Use Microsoft Disk Manager to
bring online or mount the disks. After the disks are online, a reboot operation
should result in disk drive letter reassignments. If these correct drive letter
assignments do not occur, manually assign drive letters to non-critical disks as
needed. Non-critical volumes that are accessed by mount points might have
similar issues.
l To recover the host, perform additional online recovery of any required user data
on non-critical volumes by using the NetWorker User program.
l If a folder is encrypted in Windows, for example, by selecting Folder Properties >
Advanced > Encrypt contents to secure data, it is recovered as encrypted.
However, the encryption attribute is not be set on the folder. You can manually
reset the encryption attribute after the recovery operation. This task is a
Microsoft limitation.
l Windows BMR supports backup and recovery of files and folders encrypted with
Windows Encrypting File System (EFS), and volumes encrypted with BitLocker.
After BMR, the EFS or BitLocker services might be running but the EFS
encryption attributes on files or folders must be re-enabled and BitLocker volumes
must be re-encrypted. For steps to encrypt with EFS and BitLocker, consult
Microsoft documentation.
NOTICE You cannot install the NetWorker software on volumes that are
encrypted with Microsoft BitLocker.
Procedure
1. Manually remount any non-critical volumes as needed.
2. To connect to the NetWorker server that backed up the source client data,
start the NetWorker User program by using the winworkr command with the -
s option.
For example: winworkr -s server_name
If the -s option is not used and there is only one server that is detected, that
server is connected automatically. If there are no servers that are detected or if
there is more than one server available, the Change Server dialog box appears,
allowing you to choose the server.
The numbers and dashes in the previous message form a Globally Unique
Identifier (GUID) that identifies a new entry. In this example, the GUID is for
illustration purposes only. The actual GUID that is generated when you run
the command is unique.
b. To set the safeboot option for the bootloader entry in the BCD store, type
the following command using the generated GUID:
For example:
7. Exit the ntdsutil utility by typing quit at each successive ntdsutil prompt
until the command prompt appears.
8. Type the following command at the WinPE command prompt so that the host
does not start into DSRM mode on restart.
9. Restart the domain controller in normal mode, log in, and then verify that the
authoritative changes are replicated to the Active Directory replication
partners.
Performing post-recovery tasks for hosts with Windows server roles that use
SQL Server
Procedure
1. On the target host, rebuild the SQL server by running the following Setup
command:
The Setup tool is located on the SQL Server installation media and must be run
from the command prompt with Windows Administrator privileges. Before you
run this command, ensure that the SQL group is offline except for the shared
disks.

For VMware hypervisors, use either a Windows Server 2008 (32-bit or 64-bit),
2008 R2 (64-bit), or Windows Server 2012 (64-bit) templates as the guest
operating system when you create the VM.
3. On the VM, start the WinPE ISO which starts the BMR wizard.
4. On the VM, use the BMR wizard to configure the hostname and network
configuration:
a. On the Select NetWorker Server screen, specify the name of the physical
computer as the NetWorker client.
b. On the Save Sets to Restore screen, review the selected items to restore,
and then click Next.
c. On the Select Bare Metal Recovery Backup screen, select the backup to
restore. Backups are listed in chronological order with the most recent
backup first.
d. On the Summary screen, if the save set was created with NetWorker 8.1 or
earlier, select the Restore physical computer to virtual machine (P2V)
checkbox.
If the Restore physical computer to virtual machine (P2V) checkbox is not
marked, the VM might not start successfully after the restore is complete.
Performing a manual uninstall and reconfigure of a NIC on Windows Server 2012 or Windows
Server 2012 R2
If the guest operating system is Windows Server 2008 R2 SP1, the P2V BMR retains
the NIC settings.
About this task
If the guest operating system is Windows Server 2012 or Windows Server 2012 R2,
then Windows performs some Plug-N-Play configuration during the post-BMR restart.
This activity disables the original NIC and creates a NIC.
Procedure
1. In the Device Manager, select Display disabled devices > Uninstall the
disabled NIC.
2. Configure the new NIC with the wanted network settings.
To view log files, you can use either a text editor or the nsr_render_log program,
depending on the log file format.
Viewing the log files
To view the following log files, use a text editor:
l recover.log
l WinPE_Wizard.log
To view the following log files, use the nsr_render_log program:
l Ossr_director.raw
l winpe_nw_support.raw
For example, to display the Ossr_director.raw file, type the following
command at a command prompt:
nsr_render_log "C:\logs\Client-bv1\Ossr_director.raw"
To direct the Ossr_director.raw file to a text file that can be viewed in a text
editor, type the following:
wpeutil DisableFirewall
By default, the Windows firewall is enabled on WinPE, and this action blocks the
FTP port from transferring files.
4. To move the log files to another NetWorker host, use the FTP utility.
winworkr -s server_name
If the -s option is not included, and there is only one server that is detected,
that server is connected automatically. If there are no servers that are detected
or if there is more than one server available, the Change Server dialog box
appears, enabling you to choose the server.
Windows Server 2008 R2 SP1, Windows Server 2012, and Windows Server 2012 R2
has 100 MB reserved as the System Reserved Partition. When backing up the system
state, VSS includes the System Reserved Partition (used for BitLocker and Boot
files), but the backup fails because the System Reserved Partition is offline. This can
occur if the Windows automount capability is disabled. Although there are
circumstances where the automount capability must be disabled, it can result in the
partition being offline after a restart. Automount must be enabled for a BMR backup
to succeed.
To work around this issue, use either of the following solutions:
Solution 1
From the command prompt, run DISKPART with the following commands:
DISKPART
List volume
If automount is disabled while using third party storage software or if the user
manually disabled the automount for the volume, the volumes can go offline.
This Microsoft KB article 2419286, available at http://support.microsoft.com/kb/
2419286, provides details on preventing volumes from going offline by checking and
setting the system automount attribute.
Solution 2
From the Disk Management console:
1. Access Disk Management from the command prompt:
C:\>Diskmgmt.msc
2. To bring the disk online, assign the drive letter to the 100 MB partition:
a. Right-click the 100 MB volume, and then select Change Drive Letter and
Paths.
b. Assign a new drive letter to the volume.
Assigning the drive letter ensures that the volume are online after a restart.
ping -a hostname
3. Restart the wizard. For example:
Note: After the wizard has been restarted, you can switch between the wizard
and the WinPE command line without exiting the wizard.
This message is an indication that the NIC selected by the wizard is not the NIC that
was connected to the NetWorker server when the backup was performed and the NIC
might not have connectivity to the server. This applies when searching for an available
server or specifying a specific server. To resolve the issue, select another NIC.

The patch that is mentioned in this knowledgebase article is most likely on the
Windows system if it is up-to-date. In this case, you can create and populate the
Registry keys as described in the article.
This issue is most often encountered when backing up a passive node in an MSCS
cluster and a critical volume is not on the physical host of the passive node but is
instead on the physical host of the active node.

save set output.
You can view the retention policies for data to which they have access by following
the first three steps in Setting expiration policies for data retention on page 638.
These different policies give administrators the flexibility to retain certain types of
information for less time than others, as showed in the following example.
Note: Reports not mentioned in the above table have no retention policies.
An administrator might want to set the completion message policy to a shorter period
than the completion data policy. The precise error messages about what caused a
save set backup to stop might not be relevant over a longer period. But it might be
useful to save the completion data for a somewhat longer period to help with load
balancing and trends.
The longest period (one or more years) might be a suitable selection for save set data.
This data is used to generate the NetWorker Backup Statistics reports. These reports
can be used to determine historical trends about backups and to help guide capacity
planning.
Note: The expiration policies restrict the data that can be retrieved by NetWorker
Console. In other words, reports cannot include data that is older than the data
retention policy. If, for example, an administrator changed a policy expiration
period from 1 year to 1 month and soon afterwards reset it to 1 year, 11 months of
data would be lost. Once data is cleared because of the retention policy, you can
only retrieve the data by recovering the full database.
resources. Users may only run reports for servers to which they are allowed to
manage.
Note: If no data is available for a given server, that server will not appear in any
lists, regardless of the access permissions for the user.
Report categories
The following table describes the various report categories in the NetWorker
software. Each of these categories is discussed in detail in Preconfigured reports on
page 647.
Report categories appear as folders within the Reports folder in the Reports window.
You can run these reports from the NMC GUI or from a command prompt.
Recover Statistics Provide the history of recovery operations that have been
performed by NetWorker servers.
Devices Provide information about the way devices are being used.
Manual saves Provides save set information about backup operations that
are initiated by a user with the save command, and details
about clone operations that are initiated by a user with the

Icon Description
Basic report
Drill-down report
Interactive mode
Interactive mode displays a report with dynamic components, which allow you to
update the report and display the modified results in real time. The effect of the
dynamic components depends on whether a report is viewed as a table or as a chart.
Table view
The table view in interactive mode enables you to:
l Scroll through rows of the table.
l Sort, rearrange, or resize columns in the table, in the same way you sort data in
other NMC windows.
l Use the Choose Table Columns menu to choose the columns to display, and the
order in which to display them.
l Create and view drill-down reports.
The following images provides an example of the Group Summary report in table view.
Figure 73 Group Summary in table view
Chart view
The chart view in interactive mode displays data in a chart format. You can switch
back and forth between different chart formats by selecting a format from the Chart
Type list.
The following image provides an example of a Group Summary report in Bar Chart
view.
Some legacy reports in chart view provide a Data Selector option that provides the
ability to control the information that appears in the chart. Use the Data Selector
section to display interesting and useful data groupings in chart format.
For example, in a Group Summary by Server report that is displayed in Bar Chart
format, the bar chart displays the amount of data in each group, and the Data Selector
lists the "Server" control column, making it possible to see—in one place—a summary
of groups across all servers, simply by moving through the list of servers in the Data
Selector. This could be useful for finding the group that backed up the most data, or
for balancing groups on servers.
You can limit the set of X and Y axes in the report by clearing one or more options
from the Chart Selector boxes. This does not apply to Drive Utilization reports.
l For Drive Utilization reports, hover over a chart in Save Set view or Drive view to
display a tool tip that includes this information:
n Drive (Drive view only)
n Save Set Name (Save Set view only)
n Start Time
n End Time
n Client Name
n Throughput (B/Sec)
Note: The tool tip feature for Drive Utilization reports is available only in
interactive mode.
Document mode
Document mode displays data in a static table or chart report that resembles the view
in Print Preview as shown by a PDF file viewer.
The following options are available with document mode:
l Orientation (portrait or landscape)
l Table or chart format
l Drive
l Start time
l End time
l Throughput value
Note: Document mode can display more than one chart in the document. You can
insert any or all available Y axes into the report. When you change to document
mode, print or export a report, or save a configuration, NMC uses the axis
selection that is currently set in the Chart Selector section of the Configuration
tab. The exceptions to this are stacked bar and pie charts, which display all axes
when the gstclreport command is used to generate a report.
color. Instead, in document mode, select a different chart type (bar, pie, or plot) if the
report data is complicated.
When specifying this chart type from the NMC GUI, the Chart Selector includes a
radio button that enables the display of only one element, or axis, at a time. If an
additional element is selected, it replaces the first. This limitation does not occur when
this chart type is specified from the command prompt.
l When you specify this chart type from the NMC GUI, all applicable data axes are
shown.
l When you specify this chart type from the command prompt, the gstclreport
command only displays the requested information.
To appreciate the different ways in which you can use a stacking bar chart, consider
these reports:
l NetWorker Backup Statistics Group Summary by Server — Shows statistics that
are broken down by savegroup for each server. Different blocks of color are used
for the amounts of data that are backed up by each group within the vertical bars
that represent the amount of data backed up by servers.
l NetWorker Backup Statistics Server Summary — Shows data from only one
focus, a server-centric point of view. If a stacking bar chart is selected to display a
NetWorker Backup Statistics Server Summary, the chart would display solid bars
of color to represent the servers. However, there would be no blocks of color
within the bars, because the report focuses only on the server level. The result
would therefore look like a simple bar chart.
Basic reports
The basic reports organize the collected data in a manner that focuses on a specific
datazone component, time span, or attribute. For example:
l A Server Summary of Backup Statistics provides backup statistics in a server-
centric manner.
l A Monthly Summary of Backup Statistics provides the backup statistics in a date-
centric manner.
Select the basic report that best provides the information you need.
Drill-down reports
Drill-down reports present report information in a preset sequence of basic reports.
You can save drill-down reports as customized reports in shared mode. You can only
use drill-down reports from the NMC GUI. You cannot use drill-down reports from a
command prompt.
Select a line of output in a report to generate information about the selected item in
the next report in the drill-down sequence.
For example, configure a Policy Summary Over Time category report, and then click
View report. From the generated Policy Summary report, double-click the output for
one of the policies. NMC generates a Monthly Summary report of data for the policy
that you selected in the Policy Summary report. In the Monthly Summary report,
double-click a month. NMC generates a Daily Summary report of data that is
generated on each day of the month that you selected in the Monthly Summary
report. In the Daily Summary report, double-click a day. NMC generates a Client
Summary report with information about clients for whom data was generated on the
day that you selected in the Daily Summary report. In the Client Summary report,
double-click one of the clients. NMC generates a Save Set Summary report of all save
sets associated with the client that you selected in the Client Summary report, on the
day you selected in the Daily Summary report, in the month that you selected in the
Monthly Summary, for the policy you selected in the Policy Summary report.
Note: In document mode for drill-down reports, the print and export commands do
not print or export the entire drill-down report, just the basic report that is
displayed.
Customized reports
A report that is included with NetWorker software is known as a canned reports, and
includes several configuration parameters that allow the tailoring of report data. With
customized reports, report versions can be configured—a single time—to fit the
needs of the enterprise. These reports can then be saved and rerun whenever
necessary, without having to be configured again. This feature saves time, especially
with regularly run reports that include complex combinations of parameters.
Customized reports can be run either on demand, or according to a preset schedule.
The owner of a saved report can also allow it to be shared with all users.
The Hide Other Users Reports option toggles the view of reports between:
l The owner’s reports (private and shared).
l The owner’s reports, plus all shared custom reports.
Customizing and saving reports on page 676 and Sharing a report on page 677
provide more information.
Preconfigured reports
The Reports window contains two folders that contain preconfigured reports.
The Reports folder contains preconfigured reports that enable you to query for
information about data that is created with a NetWorker 19.1 server. The Legacy
Reports folder contains preconfigured reports that enable you to query for information
about that created with a NetWorker 8.2.x and earlier server.
Preconfigured reports
The Reports folder contains preconfigured reports that enable you to generate reports
about data that was created with a NetWorker 19.1 server :
Policy statistics
The Policy Statistics report category provides you with the ability to create reports
that contain details and summary information about Data Protection Policy resources
for each selected NetWorker server within the enterprise.
The Policy Statistics report category includes basic and drill-down reports.
Policy reports
NMC provides two types of reports that provide information about Policy resources:
Policy Summary reports, and Policy Summary over time reports.
Policy Summary
A basic report that provides information that is gathered from the media database and
client file indexes about data that are generated by backup and clone actions in all
workflows that are associated with a Policy resource. The reported Information
includes the following statistics:

recovery history within 12 hours of when you run the report.
Types of NetWorker recovery reports and configuration
The NetWorker recovery report category includes basic and drill-down reports. The
different types of reports that are included within the NetWorker Recover Statistics
report category provide recover statistics for each selected NetWorker Server within
the enterprise.
The Configuration tab allows you to limit the scope of the report that was selected.
The parameters available within the NetWorker Recovery report category are
described in this table. The specific parameters available depend on which NetWorker
Recovery Statistics report is selected.
Source Client Name One or more clients whose Selected client names.
data is being recovered.
Target Client The client where the data is Selected target client names.
being recovered to.
The parameters available for each report type in the NetWorker Recovery Statistics
report category are listed in the user interface.
Recovery Statistics basic reports
Within the NetWorker Recovery Statistics report category, choose any of the basic
reports that are listed in the user interface. Once a report is chosen, the
Configuration tab displays boxes with lists of the selected parameters for that report.
To exclude unwanted parameters from the report, delete them from the list.
Customizing and displaying report output on page 673 provides information on
selecting and removing parameters.
Recovery Statistics drill-down report
This drill-down report consists of multiple NetWorker Recovery Statistics basic
reports, which are connected in a predetermined sequence. Drill-down reports on
page 646 provides general information about drill-down reports.
The configuration parameters for a drill-down report are the same as the
parameters for the top-level report in the report sequence. Thus, if the top layer
of the drill-down report is a Server Summary report, the configuration parameters
are the same as they would be for the basic report, Server Summary.
When a report is chosen, the Configuration tab displays boxes that list the
selected parameters for the top-level report.
To exclude unwanted parameters from the report, delete them from the list.
Customizing and displaying report output on page 673 provides information on
selecting and removing parameters.
To generate the Recover Summary Over Time report, you must first specify the same
parameters as those in the Server Summary report, which is the first report that is
displayed in the sequence.
To drill-down to the client level, perform one of the following, depending on the
viewing mode:
l When in table mode, double-click any individual row referencing the desired
NetWorker Server.
l When in chart mode, click anywhere in the chart area of the desired NetWorker
Server.
The Client Summary report for the selected NetWorker Server appears. Return to the
Server Summary report to select another server to explore.
To drill-down to the Recover Details level, perform one of the following, depending on
the viewing mode:
l When in table mode, double-click any individual row referencing the desired
NetWorker Client.
l When in chart mode, click anywhere in the chart area of the desired NetWorker
Client.
The Recover Details report for the selected NetWorker Client appears. Return to the
Client Summary report to select another client to explore.
Recovery data retention policy and configuration
The retention policy for the recover statistics that are used to generate these reports
can be set with the other retention policies currently defined from the Data Retention
page in the Reports task pane. The default retention policy for these statistics is one
year.
Device reports
Device reports provide information about the way devices are being used. They show
scheduled and manual backup activity on one or more selected devices over time. You
can identify periods of heavy activity or inactivity. Device reports aid NetWorker
administrators in performance tuning, and they help identify bottlenecks. For example,
if all drives are being used continuously for a long period, at maximum throughput,
backup speeds may improve by adding tape drives or moving clients to another backup
server.
Types of Device reports and configuration
The Devices report category includes only one report, the Drive Utilization report. This
report, which is a drill-down report, supports NetWorker servers running NetWorker
software release 7.3 or later. These versions are now unsupported. The report includes
backup activity data for all device types, including advanced file type devices and
digital data storage devices.
When viewing a Drive Utilization report as a chart, it is automatically displayed as a
Gantt chart, where the backup activity level of one or more devices is depicted in
relation to time. Unlike with other reports, you cannot choose an alternate chart type.
Placing the cursor over the chart in Save Set view displays a tool tip that provides this
information:
l Save set name
l Start time
l End time
l Client name
l Throughput value
Placing the cursor over the chart in Drive View displays a tool tip that provides this
information:
l Drive
l Start time
l End time
l Throughput value
Note: One of the activities in the Drive Utilization report is throughput. Since the
Drive Utilization Report provides data for backup activities only, throughput values
will normally be non-zero. However, zero (0) is considered a valid throughput
value.
Event reports
These reports provide summary information about current events on NetWorker and
Console servers within the Enterprise. Additional details about a particular event can
be displayed, including annotation contents. While the Events window within the
NetWorker Console displays the current events of the NetWorker servers, the Event
reports provide additional features. The reports enable you to organize, export, and
print the event data.
Event reports can include this information:
l Number of events
l Priority of events
l Category of events
l Server name
l Server type
l Event time
l Notes and annotations
Note: When an event has been resolved, it does not remain in the records.

To exclude unwanted parameters from the report, remove them from the list.
Customizing and displaying report output on page 673 provides information about
selecting and removing parameters.
Event drill-down reports
The drill-down reports consist of multiple Event basic reports, which are connected in
a predetermined sequence. Drill-down reports on page 646 provides general
information about drill-down reports.
The configuration parameters for a drill-down report are the same as the parameters
for the top-level report in the report sequence. Thus, if the top layer of the drill-down
report is a Server Summary report, the configuration parameters are the same as they
would be for the basic report, Server Summary. When a report has been chosen, the
Configuration tab displays boxes listing the selected parameters for the top-level
report. To exclude unwanted parameters from the report, remove them from the list.
Customizing and displaying report output on page 673 provides information on
selecting and removing parameters.
Host reports
The Hosts report category includes only basic reports. There are two basic reports, as
described in this table.
l Start from
selected folder.
Enterprise on page 750 provides a description of the Enterprise and its folders.
User reports
The Users report category provides information on NetWorker Console user activity.
NMC Server Management provides information about NetWorker Console users and
creating user accounts.
The Users report category includes only basic reports, no drill-down reports. The Full
Name and Description information appears in the User reports only if this information
was specified when the user was created.
Save Set Name Selects one or more save Selected save set names
sets.
Level Select one or more backup List of backup levels such as,
levels. Full, Incremental, Skip,
synthetic full, or Level 1–9
The parameters available for each report type in the NetWorker Backup Statistics
report category are listed in the user interface.
Save set data retention policy and configuration
Settings for the save set retention policy impact the data that is available to the
NetWorker Backup Statistics reports. If a save set retention policy of six months is
specified, NetWorker software cannot query the database for a time range that
extends back more than six months. The report cannot display data that has expired
because that data has been removed from the database. Thus, even if a save time
parameter of one year is specified, the report can display only six months of data if the
limit of the save set retention policy is six months.
Backup statistics basic reports
Within the NetWorker Backup Statistics report category, choose any of the basic
reports that are listed in the user interface. Once a report is chosen, the Configuration
tab displays boxes with lists of the selected parameters for that report. To exclude
unwanted parameters from the report, delete them from the list. Customizing and
displaying report output on page 673 provides information on selecting and removing
parameters.
Note: These basic reports do not distinguish between regular and deduplication
clients.
Backup statistics drill-down reports
Drill-down reports consist of multiple NetWorker Backup Statistics basic reports,
which are connected in a predetermined sequence. Drill-down reports on page 646
provides general information about drill-down reports.
The configuration parameters for a drill-down report are the same as the parameters
for the top-level report in the report sequence. Thus, if the top layer of the drill-down
report is a Monthly Summary report, the configuration parameters are the same as
they would be for the basic report, Monthly Summary.
When a report is chosen, the Configuration tab displays boxes that list the selected
parameters for the top-level report. To exclude unwanted parameters from the report,
delete them from the list. Customizing and displaying report output on page 673
provides information on selecting and removing parameters.

types.
The parameters available for each report type are listed in the user interface.
Completion data retention and NetWorker backup status
The settings for the completion data policy impact the data that is available to the
NetWorker Backup Status reports. The report cannot display data that has expired,
because it has been removed from the database.
Thus, even if a one-year time range is specified for the Group Start Time parameter,
the report displays only six months if the limit of the completion data policy is six
months.
Backup status basic reports
Within the NetWorker Backup Status report category, choose any of the basic reports
that are listed in the user interface. When a report has been chosen, the Configuration
tab displays boxes listing the selected parameters for that report. To exclude
unwanted parameters from the report, remove them from the list. Customizing and
displaying report output on page 673 provides information on selecting and removing
parameters.
Inactive files
A NetWorker administrator can manage inactive files on a client or group and set the
NetWorker software to automatically generate a list of inactive files in an
environment. Inactive files are files that have not been accessed or modified other
than being backed up regularly. The period of time a file has been inactive is called the
Inactivity Threshold.
The inactivity files report is not supported on releases earlier than release 7.4 of the
NetWorker servers. These versions are now unsupported.
Client support for this feature will be enabled only on Windows platforms.
The Inactive files report is a drill-down report that lists the inactive files from the
latest scheduled backup. The report operates at both the client and group level.
The inactive files report can do the following:
l Generate a report on the percentage of inactive files backed up as part of a group.
l Set the threshold time periods per group so that the percentage of inactive files in
that group does not exceed the threshold time period.
l Set alerts so that the NetWorker software sends an alert when the threshold set
for a group is exceeded.
l Provide a report that details the percentage of inactive files backed up as part of a
group.
l Report the percentage of inactive files per client.
The range limit specification given to configure File Inactivity Threshold and File
Inactivity alert threshold attributes can be configured within the following ranges:
l File Inactivity Threshold attribute can be set between 0-365 days.
l File Inactivity Alert Threshold attribute can be set between 0-99.
Group File Details
The Group file Details report provides statistical information about inactive files that
are included in a scheduled backup. Data will be provided for every requested
NetWorker group at the time of the last backup. Chart mode is the default mode for
the report. The data can also be viewed in tabular mode for more detailed information.
When generating the Group Details report, you can specify the following parameters:
l One or more NetWorker servers. Only servers that have the Gather Reporting
Data attribute turned on will appear in the selection list.
l One or more NetWorker groups for the selected NetWorker servers.

l YY-M-D (07-03-8)
Naming reports
When naming a report to save, keep in mind that the set of usable characters is limited
in the same way as for hostnames and usernames. Report names may not contain:
l Characters having an ASCII representation number less than ASCII 32 (such as
carriage return, bell, newline, escape)
l Comma (,)
l Slash (/) or backslash (\)
l Double quote (“) or single quote (’)
Note: Report names are not case-sensitive. Also, canned reports cannot be
deleted or customized, and then saved under the same name as a report that
already exists under the same parent folder or directory.
Sharing a report
By default, when you save a customized report, the report is private and appears only
in the report hierarchy. The report owner or an NMC user with the Console
Application Administrator role can share the report with other NMC users. Perform
the following steps to share a customized report.
About this task
Any user viewing a sharable report may perform these operations on the report:
l Change any runtime parameter of the report (such as configuration or view type).
l Run the report, but not save changes to the report.
l Copy the report by using the Save As command. The user becomes the owner of
the new report, and by default, the report is not shared.
l Choose the Hide Other Users’ Reports option to toggle the view of reports
between only those reports owned by the user (both private and shared), and all
shared custom reports.
Perform the following steps to share a report.
Procedure
1. From the NMC GUI window, click Reports.
2. Expand the report folder that contains the customized report that you want to
share.
3. Right-click the customized report, then select Share.
The report is now shared, and is represented in the report hierarchy by a
shared-report icon or .
Results
Once you enable a report for sharing, all users can see the report in the report folder
hierarchy.
Note: The Share option is a toggle. To disable sharing, right-click the shared
report and select Share.
System performance
Each time the gstclreport command is run, it starts a separate JVM, which can use
many system resources. The gstclreport command runs a database query and
generates report output by using the results. Since this uses both CPU and memory
resources on the host computer, it could affect performance of NetWorker software
and of the host. Consequently, depending on the system used, it is probably not wise
to run more than a few instances of the gstclreport command at the same time.
Security
The gstclreport command must contact the Console server in order to run a
report. The command requires a valid username and password. A user either uses the -
P option to type the password, or the command checks standard input to see whether
the password is there. If a password is not supplied, the program prompts for a
password.
On UNIX systems, use of the -P option is a security concern, because a user may type
the ps command and see the commands that were used to start any program that is
running.
To solve this problem, use scheduling software that can conceal password input.
Alternatively, ensure that the scheduling system sends the password as standard
input. For example:
A cron command can be used to schedule the report, or the command could be
placed in a secure script file that is invoked by the cron command.
l By querying the job status. Querying the job status on page 681 provides more
information.
l Discover job action —Job that is created for a NAS discover action.
l Generate index action job —Job that is created for a generate index action.
l Probe action job —Job that is created for a probe action.
l Utility job — Is an action that performs a maintenance task, for example, the
expire action, the vba-checkpoint-discover action, and the vba-checkpoint-backup
action. A job can start a child utility job to perform tasks that the parent job
requires to complete an action. For example, the server backup action job starts a
child job that runs the mminfo -B command.
l Vbasave job — Child job that is created by a VMware backup action job.
l Workflow job — Job that is created for a workflow.
NetWorker clears the information about a job from the jobsdb and deletes the
associated log files at the interval that is defined by the Jobsdb retention in hours
attribute in the properties of the NetWorker Server resource. In NetWorker 9.0.1, the
default jobsdb retention is 72 hours.
Using jobquery
The jobquery program provides a CLI similar to the nsradmin program. The
jobquery program contacts the nsrjobd process to query job information that is
stored in the jobsdb. A query is defined by an attribute list that is made up of one or
more attribute names with or without values.
About this task
In the query, the attribute name (for example, 'type') is preceded by a period ('.'), and
optionally followed by a colon (':') and a comma-separated list of values (for example,
"host: mars";"job state: STARTED, ACTIVE, SESSION ACTIVE"). When a query
consists of more than one attribute names, attributes are separated by a semi-colon
(';'). When an attribute name is specified without values, any resource descriptor that
contains this attribute is a match. If an attribute name is followed by one or more
values, a resource whose value list matches at least one of the values for the specified
attribute satisfies the criteria.
To launch the jobquery interface, type:
jobquery -s NetWorker_server
This example would return information on all savegroup jobs from the host mars
that are either in progress or in completed state.
l show — restricts the list of attributes that are returned for each resource
descriptor that matches the query. For the above example, specifying the
following:
returns the names, job ids, completion status, and completion severity for all
matched completed and active savegroups.
l print — runs the query and displays the results. If show list is in effect, each
resource descriptor in the result list is restricted to desired attributes.
l all — returns all resource descriptors in the jobs database. If show list is in
effect, result is restricted to desired attributes.
l help — displays help text.
l quit — exits jobquery.
Running jobquery -s NetWorker_server -i input_file reads input from
the file for non-interactive usage. The man pages or the NetWorker Command
Reference Guide provides detailed information about the jobquery program.
where policy_name is the name of the policy that contains the workflow and
workflow_name is the name of the workflow.
Note: The policy_name and workflow_name values are case sensitive.
For example, to query the jobsdb for a workflow named SQL Clients in a policy named
Backup, type the following commands at the jobquery prompt:
type table: ;
userid: ;
workflow name: SQL clients;
The following table summarizes some of the attributes that appear in workflow job
types.

Parent job id The job id of the job that started this job. A
job may not have a parent job.
Job log file The location and name of the log file that
contains detailed information about the job
activities.
Start time The time the job started, in seconds since Jan
1, 1970.
End time The time the job ended, in seconds since Jan
1, 1970.
Completion severity The severity level of any error that caused the
job to end. Severity levels include:
EMERGENCY, ALERT, CRITICAL, SEVERE,
ERROR, INTERVENTION, WARNING,
NOTICE, and INFORMATION.
Data protection policy name The name of the policy that contains the

In this example, the server backup workflow failed for a host at 7:54 PM on June 26.
We want to review session information about the action tasks started by the server
database backup and expiration actions.
In this example, two action jobs created child jobs. The server database backup
action created a child process for the nsrdbsave command and the expiration
action created a utility job. Output for the bootstrap save job appears, as follows.

Using nsrrecomp
Use the nsrreccomp program to query the jobsdb for information about recover jobs
and to create a recover completion report. The name specified for the recover job is
the name of the saved recover configuration. The nsrreccomp program differs from
the jobquery program because it also queries recover log files and is limited to
recover job information only.
Example: Summary report of recover jobs
To generate a summary report of each recover job in the jobsdb, type:
nsrreccomp -L
nsrreccomp -b -1 recover_job_name
where -b -1 is optional and used to override the default 2kb limit for job output.
Example: Summary report of the last recovery job
To generate a summary of last recovery job for a Recover resource, type:
nsrreccomp -H group_name
The UNIX man page and the NetWorker Command Reference Guide provides detailed
information about the nsrsreccomp program.
This message is reported when a backup action starts. This message reports the
names of the clients that are checkpoint-enabled, and the mode that was selected at
the time of the backup.
savegrp test: checkpoint restartable saveset
client_name:save_set created in previous run(s) of the group.
It will be checkpoint restarted. Checkpoint ID cp_id.
This message reports that a partial save set is detected for a client in the group and a
checkpoint restart occurs for the save set.

client_name:save_set failed and will not be restarted.
This message is reported when the backup of a checkpoint-enabled client fails and the
backup will not be retried.
Common reasons for this error message include:
l The restart window for the group has been exceeded.
l The maximum number of client retries has been reached.
NOTICE When this message is reported, the failed save set are removed from
an AFTD:

This message reports that the save set for a checkpoint-enabled client successfully
completed during the backup action.
SNMP traps
The NetWorker Simple Network Management Protocol (SNMP) Module allows
NetWorker servers to send notification messages to SNMP management agents.
You must configure SNMP-enabled network management software to accept traps
from the NetWorker server. For detailed information about SNMP management
operations refer to your network management documentation.
The NetWorker SNMP Module uses traps to communicate NetWorker event
notifications to SNMP management stations. A trap is an unsolicited notification sent
from the SNMP agent (the NetWorker server) to the SNMP event manager.
When you configure the SNMP notification in NetWorker, you can define the types of
traps that the NetWorker server sends to the SNMP event manager. Typical traps
include warnings, critical errors, and other messages from the NetWorker server.
NetWorker 18.2 and later includes the following SNMP trap enhancements:
Attribute Description
Server FQDN, IP address, or the hostname of the
Networker server.
4. On the Linux trap receiver, execute the following commands to receive SNMP
traps:
snmptrapd -f -C -c ./snmptrapd.conf -Le -M /usr/share/
snmp/mibs -m NETWORKER-MIB
5. Initiate the policy or workflow on the NetWorker server to view the traps.
Example 13 Using PuTTY to capture the session output for SNMP traps Saving SNMP traps log
file to a predefined location
If you are using PuTTY to capture the session output for SNMP traps, do the
following:
1. Launch PuTTY.exe.
2. Navigate to Session > Logging > All session output to capture the SNMP traps
in a log file.
3. Type the following command:
snmptrapd -f -C -c ./snmptrapd.conf -Le -M /usr/ share/snmp/
mibs -m NETWORKER-MIB
To save the SNMP traps log file to a predefined location, type the following command:
Example 13 Using PuTTY to capture the session output for SNMP traps Saving SNMP traps log
file to a predefined location (continued)
nohup snmptrapd -f -C -c ./snmptrapd.conf -Lf /var/log/
snmptrap.log -M /usr/share/snmp/mibs -m NETWORKER-MIB &
The nohup option ensures that the command runs even after the session is
terminated. Use & to run the command in the background.
2. Load the NetWorker MIB file located at the following location to the iReasoning
MIB Browser using the Load MIBs option on the iReasoning MIB Browser.
l Linux NetWorker server: /opt/nsr/snmp
l Windows NetWorker server: C:\Program Files\EMC NetWorker\nsr
\snmp
6. In the Action attribute, specify the options for the nsrtrap command:
Option Description
-c community Specifies the SNMP community that is authorized to receive
traps from the NetWorker server. You configure SNMP
communities on the SNMP server. The default setting for this
option is Public, which means that the public community can
receive traps from the NetWorker server.
-t trap_type Optional, sets the type of trap that the NetWorker SNMP
Module sends to the SNMP server. The default setting is six,
which sets the trap type to “enterprise-specific” and is the
correct type for the notifications (error messages) that the
NetWorker server sends to the SNMP server. Only modify the
trap type if you intend to send a specific trap to the SNMP
server and not a NetWorker notification.
Option Description
-s specific_trap_type Optional, allows you to customize the identity of the type of
trap that the NetWorker server sends. Set this option to any
integer value. Use this option along with different SNMP
notifications to distinguish different traps from the
NetWorker server.

NetWorker Notifications
A notification provides information about events that occur in a NetWorker
environment. You can configure the events to be reported and how the NetWorker
server reports them to you. Specific programs can be run when an event occurs,
including third-party programs. By default, the NetWorker server sends notifications
to log files that are located in the NetWorker_install_dir\logs directory on
Windows and the /nsr/logs directory on UNIX.
Preconfigured notifications
NetWorker is preconfigured to provide most of the event notifications that are
required to monitor NetWorker events. The following table lists these preconfigured
notifications and the associated actions that are performed by the NetWorker server.
Device ordering issue detect Windows: Provides the syntax for the
smptmail command to send an email to the
administrator account with the message
Check system device ordering.
Moving device on
NetWorker_server to service
mode.
File system full - recovering adv_file space Launches the nsrim program to remove
aborted and expired save sets. Used with
advanced file type devices only.
File system full - waiting for adv_file space Windows: Reports that the advanced file
volume is full to the C:\Program Files
\EMC NetWorker\logs\media.log file.
Save set marked suspect Windows: Provides the syntax for the
smptmail program to send an email to the
administrator account when a save set has
been marked suspect.
Verify Label failed on unload Windows: Provides the syntax for the
smptmail program, to send an email to the
administrator account stating that a label
verification on unload operation has failed.
Customizing notifications
Notifications require the following three elements:
l Events
l Actions
l Priorities
About Events
An event signals that user intervention is required. For example, if a NetWorker server
needs a new tape, the server alerts users to the situation by posting an event to the
Console window.
NetWorker software generates an event that is based on various factors, including the
following scenarios:
l The software or hardware encounters an error that requires user intervention to
resolve.
l A NetWorker savegroup has failed.
l Drive ordering or serial number mismatch issues — a description of the problem is
provided, along with a corrective action to fix the problem.
l Capacity monitoring — for example, reaching the space threshold on the
deduplication node.
l NetWorker software is unable to poll a host it is monitoring for events or for
generating reports.
l A license or enabler code that is managed by the License Manager is about to
expire.
Some situations do not result in the generation of an event. For example, when a
license managed by the NetWorker Console (instead of by the License Manager)
approaches its expiration date. In this situation, a message is recorded in the
NetWorker logs, but an event is not generated until the expired license causes a
backup to fail. Check the Administration window from time to time for important
messages.
Actions
The Actions attribute defines the action that the NetWorker server takes after an
event notification occurs. The following table provides a summary of actions.
Action Description
eventlog Windows only, logs the notification message to the event log.
Priority determines whether the notification is an error,
warning, or information-only message.
Note: The log file path must not include any space or
special characters, and must not be enclosed in quotes.
Action Description
sendmail NetWorker Virtual Appliance (NVE), sends an email to a
specified user.
Third-party programs can also be used for the action, if the programs support reading
from standard input.
For example:
l On UNIX systems, you can use a third-party email program rather than the mail
program.
l On Windows systems, you can use a third-party email program rather than the
smtpmail program to send the information to other locations, such as an email
address or pager system.
Only users who belong to the NetWorker server Administrators list, or a member of
the Application Administrators user group, can change the Action attribute of an
existing notification.
where:
Priorities
Each NetWorker event has a series of associated messages, and each message has an
associated priority. The preconfigured notifications have selected priorities based on
the importance of the message being sent. For example, the first time the NetWorker
server sends a mount backup volume request, the priority that is assigned to the
message is Waiting. The priority of the second request is Alert. The priority of the
third request is Critical.
The following table lists the priorities on which notifications are based.
Priority Description
Information Information about the current state of the server.

Breakthrough logging
Breakthrough logging feature in NetWorker helps you to understand the steps
involved in the various operations such as Save, Recover and Clone. Each step is
logged in the defined order to ensure successful completion of Save, Recover and
Clone operations. Breakthrough logging helps the user to review the log associated
with each step of operation and determine the step that failed during the execution of
that particular operation.
You can check logs for clone and backup at/nsr/logs/Policy/<policy name> .
You can check logs for recovery at /nsr/logs/recover.

services than the NetWorker Server that the source NMC Server used, then you must
use the gstauthcfg command on the NMC Server to update the NetWorker
Authentication Service host, and then run the nsrauthtrust commands on each
NetWorker Server that is managed by the NMC Server.
When the source NMC Server uses a different NetWorker Server for authentication
and you do not establish a trust, the following behavior occurs:
l The NMC Events window displays Unable to connect to the server
error messages for each managed NetWorker Server.
l When you try to connect to the NetWorker Server, a message similar to the
following appears: Unable to connect to the server: Unable to set
user privileges based on user token for SYSTEM: Failed to
validate security token.
Changing the Authentication service hostname and port number provides more
information.
Procedure
1. Click Setup.
2. From the Setup menu, select Migrate Users.
3. On the Migrate Users page, select the users that you want to migrate.
Note: By default all users are selected for migration. The migration deletes
unselected user accounts.
b. Leave the default selection for Password Change Required, which ensures
that when the user connects to the NMC Server for the first time, that the
log in process prompts the user to change their password.
c. In the Groups field, if the user will manage user accounts, select the
Administrators group.
Updating the NetWorker User Group resources for migrated NMC users
The NetWorker server uses the membership in the External Roles field of the user
group resources to determine the privileges that are assigned to the NetWorker
Authentication Service local database users. After the log in process migrates NMC
users into the NetWorker Authentication Service local database, update the User
Group resources on each managed NetWorker server, to provide the migrated NMC
users with the privileges to each NetWorker server.
About this task
Perform the following steps while logged in to the NMC server with the Administrator
account.
Procedure
1. In the NMC GUI, create an NMC group that contains the local database users.
This group allows you to quickly add multiple users that require the same
privileges to one or more user groups:
a. On the NMC GUI, click Setup.
b. On the User and Roles navigation pane, right-click Groups and select New.
c. In the Name field, specify a unique name for the group.
In the Local Users section, select all the user accounts to add to this group,
and then click OK.
2. In the Administration window, perform the following steps:
a. On the toolbar, select Server.
For more information on External Roles and User Groups, see NetWorker
Security Configuration Guide
Results
The distinguished name (dn) for each selected user and group appears in the External
Roles field.
l To create the Base64 encoded password on Linux, use the base64 utility.
For example, to create the Base64 encoded password for a password value
of "1.Password", type:
echo -n "1.Password" | base64
The command displays the encoded text for the password value
"1.Password": MS5QYXNzd29yZA==
{
"local_users": [
{
"user name": "administrator",
"password": "MS5QYXNzd29yZA=="
}]
}
4. Rename the authc-local-config.json.template file to authc-local-
config.json.
5. Copy the authc-local-config.json file to the Tomcat conf folder.
By default, the conf folder is/nsr/authc/conf on Linux and C:\Program
Files\EMC NetWorker\authc-server\tomcat\conf on Windows.
Note: If the NetWorker server is also the NMC server, start the NMC
server service. Type the following commands: net start gstd
l For Linux, type the following commands:
/etc/init.d/networker stop
/etc/init.d/networker start
When the NetWorker Authentication Service starts, the startup process checks
for the authc-local-config.json. If the file exists and the password
adheres to the minimum password policy requirements defined for a password,
the NetWorker Authentication Service resets the password. Review the
authc-server.log file for errors.
By default, the authc-server.log file is located in /nsr/authc/logs on
Linux and C:\Program Files\EMC NetWorker\authc\tomcat\logs on
Windows.
Note: The startup process automatically deletes the authc-local-
config.json file to ensure that the password is not reset the next time
that you restart the NetWorker Authentication Service.
8. To confirm that you can connect to the NetWorker Authentication Service with
the new password, use the authc_mgmt command.
For example:
For example:
port=2639
Note: By default the postgresql.conf file is located in the /nsr/nmc/
nmcdb/pgdata directory.
7. Confirm that the daemons have started, by typing the following command: ps
-ef | grep lgtonmc.
Output similar to the following appears when the daemons have started:
nsrnmc 7190 1 0 Nov23 ? 00:00:06 /opt/lgtonmc/bin/gstd

Note: By default the postgresql.conf file is located in the C:\Program
Files\EMC NetWorker\Management\nmcdb\pgdata directory.
4. Use the regedit command to update the port number in the registry.
a. Browse to \\HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI
\lgto_gst_pgsql.
b. Edit the Port registry key.
c. In the Value Data field, specify the new port number.
d. Click OK.
5. Start the EMC GST Service.
2. Edit the gstd.conf file and update the IP address that is defined for the line
string authssvc_hostname.
3. Browse to the NetWorker bin directory then run the platform-specific
commands:
l On Windows, run gstconfig in the NMC_install_dir\GST\bin folder.
l On Linux, as root, run the gstconfig command in the /opt/
lgtonmc/bin directory.
4. Start the gstd service:
l On Linux:
n sysvinit—/etc/init.d/gst start
n systemd—systemctl start gst
l On Windows: Start the EMC GST Service service.
5. For NMC server hostname changes only, delete the Client resource that you
created to perform NMC server database backups, then create a new client
resource.

Hostname changes
NetWorker considers each unique client name as a separate client. NetWorker assigns
each unique client name in the datazone a unique identifier called client ID. NetWorker
stores the client ID for each client in the media database.
The NetWorker software has a built-in mechanism to prevent the nsrd daemon from
starting on the NetWorker server if the startup process detects a change in the name
of the NetWorker server. For example, when you change the hostname of the
NetWorker server or modify the aliases order in the hosts file.
A message similar to the following appears in the daemon.raw file:
This mechanism prevents the NetWorker software from assigning a new client ID to
the NetWorker server, which is based on the new hostname. To resolve this issue,
verify the hostname resolution of the NetWorker server. The "Networking and
Connectivity" chapter provides more information.
If the startup process did not detect the hostname change, NetWorker assigns the
NetWorker server a new client ID, which can impact NetWorker operations. Use the
nsrclientfix command to analyze the media database and identify client ID
inconsistencies. To resolve client ID issues, use the nsrclientfix command to
merge information about multiple clients in the media database and resource database
into one client resource with the original client ID. The following KB articles on the
Online Support website provide more information about using the nsrclientfix
command:
l For NetWorker Server client ID issues: 000185727
l For NetWorker Client client ID issues: 000193911

The Command Reference Guide provides more information about the nsrtask
and NSR client fix resources.
Parallelism
You can use several attributes in various NetWorker resources to adjust the volume of
data that a host processes to improve overall performance.
The following attributes are related to parallelism:
l Client parallelism
l Server parallelism
l Action parallelism
l Max active devices
l Media library parallelism
These attributes are described in detail in the following sections.
The default value is different for the NetWorker server than it is for all other client
resources:
l For the NetWorker server client resource, the default value is 12. This higher
default value enables the server to complete a larger number of index backups
during a Server backup action.
l For all other clients, the default value is 4.
To define client parallelism, use the Parallelism attribute of the Client resource. You
can find the parallelism attribute on the Globals(1 of 2) tab of the Client property
dialog box, in the NetWorker Administration window.
The NetWorker Network Data Management Protocol (NDMP) User Guide provides more
information about recommended parallelism settings for NDMP clients.
To avoid disk contention for clients other than the NetWorker server, specify a value
that is the same as or fewer than the number of physical disks on the client that are
included in the backup.
For a Windows client with the ALL keyword save set attribute, the backup includes the
local disks, for example C: and D: drives as well as the System State and System DB.
In this example, you can keep the default parallelism setting of 4. If you define multiple
save sets on the same disk, for example, C:\users, C:\system, C:\docs and so
on , a higher client parallelism results in multiple save streams attempting to access
the disk at the same time.
The NetWorker Performance Optimization Planning Guide provides more information
about recommended client parallelism values and performance benefits.
Enabling the parallel save streams (PSS) feature for a Client resource allows you to
back up each save set for the client by using multiple parallel save streams to one or
more destination backup devices. You can use PSS to perform the scheduled file level
backup of file systems, and block based backups.
You can use PSS for clients with supported UNIX, Linux, and Windows operating
systems. Supported save sets for PSS include the Save Set ALL, and individual save
points including Disaster_Recovery, deduplicated, and CSV volumes (Windows
only). Checkpoint restart is not supported when you use PSS.
When you enable PSS, you can specify the maximum number of save streams that a
client can send simultaneously for one or more save set backups concurrently running
by using the Parallelism attribute in the Client Properties dialog. The default value
for the Parallelism attribute is different for the NetWorker Server than it is for all
other Client resources:
l For the NetWorker Server Client resource, the default value is 12. This higher
default value enables the server to complete a larger number of index backups
during a file system backup of the server or other index backups.
l For all other clients, the default value is 4.
Enabling PSS results in significant performance improvements due to save set
aggregation, where the NetWorker Server starts a single save process per client with
all client save sets that are passed to the single process for various processing
optimizations, such as minimal Windows VSS snapshots and support for the following:
l Four parallel streams are started per save set, subject to any client parallelism
limitations that might prevent all save sets from starting simultaneously.
l The ability to modify the number of parallel streams per save set by defining the
new PSS:streams_per_ss environment variable save operations attribute in the
properties of a Client resource. For example, setting PSS:streams_per_ss=2,*
splits all save sets into two parallel save streams, whereas
Server parallelism
To define the server parallelism for a NetWorker server, use the Parallelism attribute
of the Server resource. The Parallelism attribute appears in the NetWorker
Administrator window on the General tab of the Server property dialog box.
Server parallelism defines the number of simultaneous data streams that the
NetWorker server allows.
Data streams include backup data streams, savefs processes, and probe jobs.
The default and the maximum server parallelism values vary depending on the edition
of NetWorker software. Each storage node that you enable and connect to the
NetWorker server can increase the parallelism maximum value. The maximum
parallelism value for any NetWorker server and storage node combination can vary.
The NetWorker Release Notes provides more information.
Optimally, configure the NetWorker server to process enough data streams to keep all
the backup devices in the datazone writing at their maximum speed. When you tune
the server parallelism setting, along with other settings discussed in this section, you
can maximize the speed that NetWorker writes the data to backup devices.
Action parallelism
Action parallelism defines the maximum number of simultaneous data streams that can
occur on all clients in a group that is associated with the workflow that contains
action.
Data streams include backup data streams, savefs processes, and probe jobs.
To define the parallelism for an action, modify the Parallelism attribute on the Specify
the Advanced Options page in the Action wizard. For a Backup action, the default
parallelism value is 100 and maximum value is 1000. For a clone action, the default
parallelism value is 0. For all other action types, the default value is 0, or unlimited.
Multiplexing
Multiplexing is the ability to write multiple data streams simultaneously to the same
storage device. It is often more efficient for the NetWorker server to multiplex
multiple save sets to the same device. There are also times when limiting the number
of data streams to a particular device improves performance of the NetWorker
environment.
Use the Target sessions, Max sessions, and Pool parallelism attributes to increase or
limit the number of data streams that NetWorker writes to a device.
Target sessions
Use the Target sessions attribute on the Configuration tab of the Device resource to
define the optimal number of backup sessions to assign to an active device.
Target sessions is not a hard limit; to set a hard limit for the number of sessions that a
particular device can accept, use the Max sessions attribute.
The Target sessions attribute aids in load balancing devices by determining when the
NetWorker software should write save streams to a device.
When a save session starts, the following actions occur:
l If a device is already receiving the number of backup sessions determined by the
target sessions value, the NetWorker server uses the next underutilized device for
the backups.
l If all available devices are receiving the number of backup sessions determined by
their target sessions value, the NetWorker server overrides the set value and uses
the device with the least activity for the next backup session.
Because it is often more efficient for the NetWorker server to multiplex multiple save
sets to the same device, rather than write each save set to a separate device, the
NetWorker server attempts to assign to each device a number of save sets, up to the
value of target sessions, before assigning a save set to another device.
NOTICE When the NetWorker software assesses how many devices need to be
involved in multiple save streams assignments with the same storage node, the
device with the lowest target session value is used as a reference.
Max sessions
The Max sessions attribute on the Configuration tab of the Device resource defines
the maximum number of save sessions for a device. The max sessions value is never
less than the target sessions value. It is recommended to use the default values for
Max sessions as lowering these values can impact performance.
Pool parallelism
The Max parallelism attribute on the Configuration tab of the Pool resource defines
the parallelism for a pool.
Pool parallelism determines the maximum number of simultaneous save streams for
each device that belong to a NetWorker pool. The default value for this attribute is 0,
which means that the attribute has no effect on other parallelism settings.
You can use pool parallelism to increase recovery times. For example, you can create a
pool to back up business critical data and use this attribute to restrict the number of
save sets that NetWorker writes in parallel to the media in the pool. As a result,
recovery speed increases for data on that media.
However, when you set the Max parallelism attribute to 1,a prolonged delay between
the backup of save sets may occur. To resolve this issue, increase the Max parallelism
attribute for the pool resource.
Note: For AFTD and DD Boost devices, the Max nsrmmd count setting for a device
affects the Max parallelism attribute. For example, consider an AFTD device
(AFTD_1) that has a Max sessions attribute of 20 and a Max nsrmmd count of 4.
Now suppose a backup pool with a Pool parallelism attribute of 1 selects AFTD_1 .
The total number of save sessions that NetWorker can initiate for AFTD_1 is 4,
one for each nsrmmd process. Tape and FTD devices can only spawn one nsrmmd
process at a time, so if the previous example used a tape device, then the total
number of save sessions would be 1.
Resource databases
Information about the NetWorker Server resides in series of files in the following
directories:
NetWorker_install_path\res\nsrdb\00
.
NetWorker_install_path\res\nsrdb\09
NetWorker stores each resource in a separate numbered file. As you create resources,
for example, a new Client, Group, or Pool resources, the NetWorker Server adds files
to the directories.
A Client resource database (nsrexec) also exists on each NetWorker host and
contains configuration information about each NetWorker host. The nsrexec
database resides in a series of files in the following directories:
NetWorker_install_path\res\nsrladb\00
.
NetWorker_install_path\res\nsrladb\09
The NetWorker Security Configuration Guide provides more information about the
Client resource database.
nsradmin -s server_name
l To access the client resource database, use the following command :
nsradmin -p nsrexec
l To access the Package Manager database, use the following command:
nsradmin -p nsrcpd
The NetWorker server removes any corrupt resource files from the nsrdb directory
structure and places them in the dbg directory. NetWorker creates the dbg directory
only after resource database file corruption has occurred. To correct this issue, open
the corrupt file with a text editor and review the file contents, then re-create the
resource. You can delete the corrupted resource file.
Note: If you do not know the cause of the resource file corruption, contact
Technical Support assistance.
Indexes
The NetWorker server tracks the files it backs up in two databases, which are stored
on the local file system of the server:
l The client file index tracks the files that belong to a save set. There is one client
file index for each client.
l The media database tracks:
n Volume name
n Backup dates of the save sets on the volume
n File systems in each save set
Unlike the client file indexes, there is only one media database per server.
The client file indexes and media database can grow to become prohibitively large over
time. Managing the size of the online indexes on page 806 provides information about
managing the size of these indexes.
NetWorker uses browse and retention policies to manage the lifecycle of the data, and
to automatically control the size of the client file index. Backup retention on page 378
provides information about policies.
nsrck -L5
If the index is still corrupt, recover the index by using the procedure that is outlined in
Adding information about recyclable save sets to the client file index on page 553.
It is recommended that you periodically run the nsrck -F and nsrim -X commands
to check the integrity of the client and media indexes. The NetWorker Command
Reference Guide or the UNIX man pages provide more information about these
commands.

Procedure
1. From the Administration window, click Media.
2. Click Indexes.
3. Right-click the client whose save sets you want to view, then click Show Save
Sets. The Index Save Sets dialog box appears.
4. To view detailed information about a save set, click the save set name.
Results
You can also use the mminfo -av command to query the media database. The
NetWorker Command Reference Guide or the UNIX man pages provides detailed
information about how to use the mminfo command.
4. Click Yes to continue. The NetWorker server displays a status box until the
cross-checking is complete.
7. On the Globals (2 of 2) tab, in the Index Path attribute, specify the full path of
the directory where the client file index now resides.
8. Click OK.
NOTICE Depending on the size of the client file index, running either nsrck
or nsrls can take a considerable amount of time. Running the nsrck -L6
command, as shown in the example, also checks the index for corruption.
If no problems are found, then all future client file index information is saved to
the new location.
l Modify the Retention policy associated with a particular save set by using the
nsrmm -e command. Unless the associated save set contains a large number of
files, this method may not be a practical method to reduce the index size. Editing
retention for a save set on page 381 provides details.
If the size of the client file index for a client is still too large, consider moving the
location of the index. Moving a client file index on page 805 provides details.
2. Use mminfo to determine the save set ID. At the command prompt, type:
mminfo -v -c client_name
The UNIX man page and the NetWorker Command Reference Guide provides
detailed information about the nsrmm and mminfo commands.
Results
When NetWorker marks a save set as recoverable, you cannot browse to recover
these files. Use the save set recover procedure to recover data from a recoverable
save set.
nsrmm -d -S ssid
To remove information about the volume from the client file index only, type the
following command:
nsrmm -d -P volume_name
Internationalization
The NetWorker software supports language packs, which you can install as part of the
NetWorker installation, or you can install the language packs separately after you have
installed the NetWorker software. The NetWorker Installation Guide provides more
information.
Internationalization support in the NetWorker software depends on
internationalization support of the underlying operating system. If you plan to use non-
English data in the NetWorker software, ensure that you install and configure the
appropriate support for that language on the operating system.
The following sections describe a number of issues and limitations that relate to the
use of NetWorker software in a multi-language environment.
Display issues
There are number of issues and limitations associated with displaying characters in
various locales.

9. From the Destination Pool list, select the media pool in which to store the
backup data.
10. From the Retention lists, specify the amount of time to retain the backup data.
After the retention period expires, the save set is marked as recyclable during
an expiration server maintenance task.
11. Specify whether to include the client file indexes in the server backup by
selecting or clearing the Perform CFI checkbox.
When you clear this option, the action will only backup the bootstrap.
12. Specify whether to include a bootstrap backup in the server backup by
selecting or clearing the Perform Bootstrap checkbox.
When you clear this option, the action will only backup the client file indexes.
NOTICE You must select either the Perform CFI checkbox, the Perform
Bootstrap checkbox, or both checkboxes. Otherwise, the server backup
action does not back up any data.
15. In the Retry Delay field, specify a delay in seconds to wait before retrying a
failed probe or backup action. When the Retry Delay value is 0, NetWorker
retries the failed probe or backup action immediately.
Note: The Retry Delay option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types. When you specify a
value for this option in other actions, NetWorker ignores the values.
16. In the Inactivity Timeout field, specify the maximum number of minutes that a
job run by an action can try to respond to the server.
If the job does not respond within the specified time, the server considers the
job a failure and NetWorker retries the job immediately to ensures that no time
is lost due to failures.
Increase the timeout value if a backup consistently stops due to inactivity.
Inactivity might occur for backups of large save sets, backups of save sets with
large sparse files, and incremental backups of many small static files.
Note: The Inactivity Timeout option applies to probe actions, and the
backup actions for the Traditional and Snapshot action types. If you specify
a value for this option in other actions, NetWorker ignores the value.
17. In the Parallelism field, specify the maximum number of concurrent operations
for the action. This is applicable if multiple rollover is implemented at an action
level.
For Direct-NDMP backups, set the parallelism value to the number of available
NDMP drives.
If you set the parallelism attribute to a higher value, there will not be enough
drives to support all the queued backup save sets. Large save sets might fail
due to the inactivity timeout limit.
When NDMP groups back up simultaneously, divide the number of drives by the
number of groups. Use this value for each of the parallelism attributes.
Setting the parallelism value for the group overrides the parallelism value that is
defined for the NDMP clients.
18. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but
continue with subsequent actions in the workflow, select Abort action.
Note: The Abort action option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types.
l To abort the entire workflow if there is a failure with one of the jobs in the
action, select Abort workflow.
Note: If any of the actions fail in the workflow, the workflow status does
not appear as interrupted or cancelled. NetWorker reports the workflow
status as failed.
19. From the Send Notifications list box, select whether to send notifications for
the action:
l To use the notification configuration that is defined in the Policy resource to
send the notification, select Set at policy level.
l To send a notification on completion of the action, select On Completion.
l To send a notification only if the action fails to complete, select On Failure.
20. From the Soft Limit list, select the amount of time after the action starts to
stop the initiation of new activities. The default value of 0 (zero) indicates no
amount of time.
21. From the Hard Limit list, select the amount of time after the action starts to
begin terminating activities. The default value of 0 (zero) indicates no amount
of time.
22. (Optional) Configure overrides for the task that is scheduled on a specific day.
To specify the month, use the navigation buttons and the month list box. To
specify the year, use the spin boxes. You can set an override in the following
ways:
l Select the day in the calendar, which changes the action task for the
specific day.
l Use the action task list to select the task, and then perform one of the
following steps:
n To define an override that occurs on a specific day of the week, every
week, select Specified day, and then use the lists. Click Add Rules
based override.
n To define an override that occurs on the last day of the calendar month,
select Last day of the month. Click Add Rules based override.
Note:
n You can edit or add the rules in the Override field.
n To remove an override, delete the entry from the Override field.
To perform expiration every day, select Execute from the list, and click Make
All.
9. Click Next.
The Expiration Options page appears.
10. Click Next.
The Specify the Advanced Options page appears.
11. From the Failure Impact list, specify what to do when a job fails:
l To continue the workflow when there are job failures, select Continue.
l To abort the current action if there is a failure with one of the jobs, but
continue with subsequent actions in the workflow, select Abort action.
Note: The Abort action option applies to probe actions, and the backup
actions for the Traditional and Snapshot action types.
l To abort the entire workflow if there is a failure with one of the jobs in the

Note: Before adding the FQDN or shortname to the NetWorker server file, ensure
that the host name resolution for FQDN or short name is working correctly.
The NetWorker Security Configuration Guide provides more information about client-
tasking rights and how to modify the servers file.
The Hosts window contains a taskbar and two window panels, the summary panel and
a task monitoring panel.
The information that appears in summary panel changes based on the task option that
you select on the taskbar. The following table provides an overview of the information
that appears in the summary panel when you select a task on the taskbar.
The NetWorker Updating from a Previous Release Guide describes how to use the
Software Inventory and Software Repository panes to update the NetWorker
software on known hosts.
The task monitoring panel is always visible for each task option. A splitter separates
the task monitoring panel from the summary panel. You can click and move the splitter
to resize the task monitoring panel.
The task monitoring panel contains three window panes:

For example, to update the Disable Directed Recover attribute, type the
following:
more than one instance of the same RDZ. By using multiple instances of an RDZ,
the global administrator can divide and assign specific tasks and privileges among
the tenant administrators and users of that RDZ.
l Tenant/Restricted User—A user that exists only within the RDZ to which they are
assigned, and who has no administrative privileges in that datazone. NetWorker
does not support a tenant user in two RDZs simultaneously.
Administrator roles
Management and use of RDZs is divided among global administrators and tenant
administrators. A global administrator creates and manages RDZs. The global
administrator can perform all the RDZ tasks, or associate specific tasks and privileges
within each RDZ to one or more RDZ users as tenant administrators.
Although there are many possibilities for the roles of administrators, most setups fall
into the following two approaches:
l Global administrator sets up the initial configuration, and also configures
everything, so there is no need for a tenant administrator. This approach may be
preferred for a customer with a very large environment, where one individual
controls the network and sets up RDZs for various divisions within their company.
l Global administrator sets up the initial configuration, and tenant Administrators
can configure and operate clients and create, view, operate, manage, and modify
the NetWorker resources that are associated with their own RDZ according to the
privileges assigned by the global administrator. Controls can be put in place to limit
a tenant administrator's impact on the server. The global administrator can restrict
the NetWorker resources that each RDZ can use, such as the maximum number of
clients, devices, jukeboxes, or storage nodes.
Figure 90 Create Restricted Data Zone in the NetWorker Administration Server window
2. Create the RDZ (for example, RDZ1) by naming the RDZ and specifying any
restrictions.
Use the Restrictions subsection to set limits on the clients, devices, storage
nodes, and jukeboxes that can be owned by the restricted datazone to prevent
resource abuse and limit what the tenant administrator can create. Setting
restrictions can provide more control for major events that may impact the
server, licensing limitations, and so on. These restrictions are in place even if
using the RDZ as a global administrator.
Note: Setting a resource restriction to a value of 0 indicates that the user
cannot create this resource.
If you plan to have a tenant administrator or tenant user, do the following:
a. Specify the user using the External Roles or Users parameters.
b. Under Privileges, select the privileges that the user will have in the RDZ.
Typically, an RDZ tenant administrator will have all privileges, while a tenant
user will have limited privileges.
You can specify multiple users. However, they will each have the same
privileges. To set up separate users with different privileges within the same
RDZ, create a separate instance of the RDZ by repeating the above steps using
the same RDZ name and restrictions, but with different External Roles, Users,
and Privileges.
If the global administrator is going to administer the RDZ and if there are no
RDZ users, then the User Configuration section of the Create Restricted
Data Zone window can be ignored.
3. In the left navigation pane of the Protection window, right-click the desired
resource (for example, Client) and select Properties to configure the resource
with the RDZ. Note that in addition to using an existing resource, you can also
create the resource for the RDZ.
5. (Optional) In the left navigation pane of the Devices window, select a device if
you want to give this RDZ client access to a specific device by right-clicking the
device and selecting Properties. Give the RDZ client access to this device.
Figure 92 Restricted Data Zones in Device Properties window
Note: The RDZ can access the shared devices without any further device
setup requirements for the shared resource if these devices are configured.
Note, however, that multiple RDZs cannot simultaneously access the same
device.
8. Create a group. In the Protection window, right-click Group, and select New.
9. Name the group and select the desired client(s). In the Restricted Datazone
tab, select the RDZ from the drop-down, then click OK.
10. In the Protection window, highlight the new policy and create a workflow.
Associate this workflow with the new group.
Figure 94 New workflow associated with RDZ group
Note: You only must configure the policy and group resources for RDZ
when using policies. The workflows and actions that are created as a result
of it are kept within the policy feature and do not need any further RDZ
configuration.
11. Return to the Server window and highlight Restricted Datazones. Right-click
and select Properties.
12. Browse to the Clients tab. This tab now shows the clients that are associated
with this RDZ. When a user belongs to an RDZ and creates a resource, this
resource is automatically set to being owned by that RDZ.
Backward compatibility
RDZ is a feature of the server and storage node, so the client does not necessarily
have to be upgraded to match the server version. RDZ is backward compatible with
the NetWorker client if that client is supported with the NetWorker 19.1 server.

Overview
The NetWorker block based backups are high-performance backups which are
supported on Windows and Linux.
During block based backups, the backup application scans a volume or a disk in a file
system, and backs up all the blocks that are in use in the file system. Block based
backups use the following technologies:
l The Volume Shadow Copy Service (VSS) snapshot capability on Windows and
Logical Volume Manager (LVM) and Veritas Volume Manager (VxVM) on Linux to
create consistent copies of the source volume for backups.
l The Virtual Hard Disk (VHDx), which is sparse, to back up data to the target
device.
Block based backups support only the following Client Direct enabled devices as
target devices:
l Advanced File Type Devices (AFTDs)
l Data Domain devices
l Cloud Boost devices
The block based incremental backups use the Change Block Tracking (CBT) driver to
identify the changed blocks, and back up only the changed blocks.
Block based full and incremental backups are fast backups with reduced backup times
because the backup process backs up only the occupied disk blocks and changed disk
blocks respectively. Block based backups can coexist with traditional backups.
Block based backups provide instant access to the backups. The block based backups
enable you to mount the backups by using the same file systems that you used to back
up the data.
Block based backups provide the following capabilities:
l Mounting of a backup as a file system
l Mounting of an incremental backup
l Sparse backup support
l Backups to disk-like devices
l Backups of operating system-deduplicated file systems as source volumes on
Windows
l Forever virtual full backups to Data Domain
l Data Domain retention lock
l 38 incremental backups to AFTD and Cloud Boost devices
l Synthetic full backups to AFTD and Cloud Boost devices
l Backups of volumes up to 63 TB each
l NetWorker-supported devices as secondary devices for backups
l Recoveries from Data Domain without using CIFS share
l Recovery of multiple save sets in a single operation
l Setting parallel save streams if the target or destination is Data Domain
The following table lists the backup scenarios and the recovery scenarios that block
based backups support.

Limitations
NetWorker's block based backups and recoveries do not support the following
capabilities and configurations:
l FAT32 file system
In the case of the ALL save set backups, either unmount or remove the FAT32
volumes, and perform the backups.
l Live updates and service patches for Ubuntu 14.04 and 16.04
l Backup levels 1 through 9
l Backups of Microsoft 2012 clusters without Cluster Shared Volumes
l Incremental backups of Microsoft clusters
l Cloning of AFTD incremental backups
l Granular save sets at either the folder level or the file level, for example, D:\data
l Checkpoint restart
l Standard NetWorker directives
l The scanner command with the -i option for rebuilding indexes for block based
backups
l Staging and the nsrclone command with the -m option for migrating block based
backup save sets to other volumes
l Image recovery to a system volume
l Recoveries of ReFS volumes on Windows Server 2008 R2 SP1 and Windows 8
(x86 and x64)
l Recoveries of Windows deduplicated volumes to Windows Server 2008 R2 SP1
and Windows 8 (x86 and x64)
l Troubleshoot kernel on RHEL, and Trace and Xen kernels on SLES
Note: Consider the following notes about parallel save streams and save
sets:
l When a backup contains more than four save sets, the parallel save
streams value must be either greater than or equal to the number of
save sets.
l The parallel save streams per save set value is the same for all the save
sets of the client, that is, you cannot set the value of one save set to 2
and the value of another save set to 4 on the same client.
[Optional] Creating an AFTD CIFS share on Windows for block based recoveries
You must enable a CIFS share to access save sets on the device to recover data from
an AFTD. The access credentials are the same as the administrator’s credentials on
the host.
Procedure
1. Right-click the folder that you want to share, and select Share with > Specific
people....
2. In the File Sharing dialog box, select or add the people with whom who want to
share the folder, and click Share.
Scheduled backups
NetWorker supports block based backups for all scheduled backups.
The scheduled backup process is transparent to you and does not require any
additional actions or considerations.
Incremental backups
You must perform an incremental backup of a volume only to the same device, to
which a full backup of the volume was performed.
Note: Incremental backups can span across multiple storage units on the same
Data Domain device.
On AFTDs, selecting any backup level apart from full or incremental results in
performing an incremental backup.
An incremental backup shifts to a full backup when any of the following conditions
occur:
l You restart the client host for any reason when the backup is either in progress or
scheduled.
l The preceding incremental backup failed.
Note: This condition applies only to Windows. On Linux, an incremental backup
continues even if its preceding incremental backup failed.
l You already performed 38 incremental backups to AFTD.
Note: After you perform a full backup, you can perform a maximum of 38
incremental backups.
l You add a volume for the backup of the ALL save set.
l You change the size of the volume.
The incremental backup process is transparent to you and does not require any
additional actions or considerations.
l The client-initiated block based backup supports the full level save sets that you
define only at the volume level.
l Do not name a manual snapshot with the same name as the block based backup
snapshot.
If a block based backup snapshot and a manual snapshot have the same name,
performing the manual snapshot deletes the block based backup snapshot.
CSV backups
You can simultaneously see Cluster Shared Volumes (CSVs) across all nodes. The
block based backups support only full backups of CSVs, even in the case of a failover.
If you try to perform an incremental backup, the backup shifts to a full backup with a
warning message.
To list the block based virtual full backup save sets, run the following command:
To list the block based synthetic full backup save sets, run the following
command:
2. Verify whether all the selected save sets have been successfully backed up.
If you want to recover data from either an AFTD or a Data Domain device by using the
CIFS or NFS share, enable the CIFS or NFS share to access save sets on the device.

NetWorker supports the use of Internet Protocol version 6 (IPv6) in a dual stack or in
a pure IPv6 environment. NetWorker does not support NetWorker resource
configurations that use temporary or link-local IPv6 addresses.
When a NetWorker host uses IPv6 addressing, ensure that you add the IPv6 address
for the host in DNS Server or the hosts file and to the alias field in the client resource.
The NetWorker Installation Guide provides information about using NetWorker in an
IPv6 environment.
Note:
1. In a configuration without reverse DNS entries, NetWorker supports FQDN
only. For information on how to use IP address, see the troubleshooting
section.
2. Forward DNS entry is mandatory for every host present in the NetWorker
datazone.
3. NetWorker Client, NetWorker Server, NetWorker Storage Node and
NetWorker Management Console (NMC) must be using NetWorker 18.1 or
later.
4. NetWorker will not change the behavior of third party applications interacting
with NetWorker that mandates the requirement of reverse DNS lookups.
5. If the IP address or the short name is used for any of the NetWorker
operations, then the /etc/hosts should be updated or ALIASES should be
defined.
3. Check that the source and destination hosts consistently and correctly resolves all
names and IP addresses for each host. Verifying name resolution on page 860
provides more information.
4. Verify that the configuration of the source and destination host includes all
relevant information for each host in the Aliases attribute and the servers file.
Verifying the NetWorker configuration on page 864 provides more information.

personal or external firewall exists between the source and the destination hosts, then
review the NetWorker configuration port requirements.
The EMC NetWorker Security Configuration Guide provides more information about how
to configure NetWorker in a firewall environment and the correct program numbers
for each NetWorker daemon.
For example, when the operating system checks the hosts file first and then
DNS, the NSORDER environment variables appears as follows:
NSORDER=local,bind4
n The hosts database entry in the /etc/netsvc.conf file.
For example, when the operating system performs name resolution checks by
using the DNS Server and then the hosts file, the hosts entry in the
netsvc.conf file appears as follows:
hosts=local,bind4
n The /etc/irs.conf file.
For example, when the operating system checks the hosts file first and then
the DNS (IPv4 address), the hosts entries in irs.conf file appear as follows:
hosts local
hosts dns4
::1 localhost
127.0.0.1 localhost
Note: The IPv6 loopback entry must remain in the hosts file when the host
exists in a pure IPv4, pure IPv6, or dual stack configuration.
Procedure
1. Determine the Primary and Secondary DNS Servers that the host uses for name
resolution:
l On UNIX, review the /etc/resolv.conf file.
l On Windows, type the following command from a command prompt:
ipconfig /all
2. Use the nslookup command in interactive mode to validate forward name
resolution lookups with the Primary DNS Server:
a. From a command prompt, type: nslookup
b. At the nslookup command prompt, specify the following values:
Shortname_of_source_host
FQDN_of_source_host
IP_address_of_source_host
Shortname_of_destination_host
FQDN_of_destination_host
IP_address_of_destination_host
Note: It is recommended that you resolve every name and IP address for
each host three times to ensure that successive queries return correct
and consistent values.
3. Complete the following steps when the host uses multiple DNS Servers for
name resolution:
a. Change the DNS Server that nslookup uses for name resolution.
In this example, the ipconfig /all command on a Windows host returns
two DNS Servers, the Primary DNS Server 10.5.5.10, and secondary DNS
Server 10.5.5.11.
To configure nslookup to use the IP address 10.5.5.11, type the following
commands:
C:\>nslookup
Default Server: lad.corp.com
Address: 10.5.5.10
> server 10.5.5.11
Default Server: dmd.corp.com
Address: 10.5.5.11

each host three times to ensure that successive queries return correct
and consistent values.
set q=ptr

Use the appropriate command to even the contents of the resolver cache:
l On AIX and HP-UX:
n For bind 9, type:
rndc flush
n For bind 8, type:
refresh -s named
l On Solaris and Linux, restart the nscd daemon.
l On Windows, type:
ipconfig /flushdns
If you receive this message but the requesting host requires access, then manually
edit the servers file on the destination host and add each short name and FQDN for
the requesting host, on a separate line.
NOTICE After you make changes to the servers file, stop and then restart the
NetWorker Server services on the host. The NetWorker Security Configuration
Guide provides more information about how to modify the servers file.
l Specify all short names and FQDNs for the host, including any retired hostnames.
l Specify each name on a separate line.
When the name returned by the operating system name lookup does not exist in any
Aliases attribute for any client, a message similar to the following appears in the
daemon.raw file:
Storage node The client sends backup data The Storage Nodes attribute

2. Create a Client resource for the storage node. Update the Aliases attribute to
include the FQDN and the shortname for each storage node NIC. This figure
shows the values in the Aliases attribute.
Figure 97 Configuring the Aliases attribute for NetWorker Storage Node Client resource
3. Update the Storage Nodes attribute for each Client resource in VLAN1 to
contain the hostname of the NIC for the storage node to which the client
connects. For example, for NetWorker Client VLAN1_client, specify the storage
node hostname sn1. This figure shows the values in the Storage Nodes
attribute.
4. Update the Aliases attribute for each Client resource in VLAN1 to contain the
FQDN and shortname of the client. The Server network Interface attribute
must contain the hostname of the NIC for the NetWorker Server to which the
client connects. This figure shows the values in the Aliases and Server
network interface attributes.
Figure 99 Aliases and Server network interface attributes for VLAN1 clients
5. Update the Storage Nodes attribute for each Client resource in VLAN2 to
contain the hostname of the NIC interface for the storage node to which the
client connects. For example, for NetWorker Client VLAN2_client, specify the
storage node hostname sn2. This figure shows the values in the Storage Nodes
attribute.
6. Update the Aliases attribute for each Client resource in VLAN2 to contain the
FQDN and shortname of the client. The Server network Interface must
contain the hostname of the NIC interface for the NetWorker Server to which
the client connects. This figure shows the values in the Aliases and Server
network interface attributes.

7. Create the Device resource on the remote storage node by specifying either
one of the hostnames for the storage node.
NIC Teaming
NIC Teaming is a term that describes the use of multiple network interfaces in parallel.
NIC teaming increases the link speed beyond the limits of any one cable or any one
port and increases redundancy for higher availability.
Other terms for NIC Teaming include link aggregation, Ethernet trunk, port channel,
port teaming, port trunking, link bundling, EtherChannel, Multi-Link Trunking (MLT),
and NIC bonding.
NIC Teaming at the TCP level, regardless of the protocol or algorithm used, has no
effect on a single TCP session. When you combine multiple links into a single link, the
backup performance of a single session does not improve.
Depending on the algorithm used, starting parallel backup jobs with multiple NICs
produces load balancing and can improve backup performance. To achieve load
balancing, use a TCP session-based link aggregation algorithm and not a host-based
algorithm. For example, use the IEEE 803.3ad/802.1ax Link Aggregation Control
Protocol (LACP).
The use of trunked interfaces is transparent from a NetWorker point of view and the
configuration of trunked interfaces inside NetWorker does not differ from the
configuration of stand-alone interfaces. You can combine TCP trunking with
multihoming, for example, by trunking some NICs on the system and leaving other
NICs to work on separate subnets.

5. To define the path and file name for the rendered log file, use the Runtime
rendered log attribute.
For example, to save rendered messages to the file rendered.log in the
default NetWorker logs directory on a Windows host, type:
Table 152 Raw log file attributes that manage log file size
Attribute Information
Maximum size MB Defines the maximum size of the log files.
Default: 2 MB
Maximum versions Defines the maximum number of the saved log files.
Default: 10
Runtime rollover by size When set, this attribute invokes an automatic hourly check of
the log file size.
Table 152 Raw log file attributes that manage log file size (continued)
Attribute Information
Default: disabled
Runtime rollover by time When set, this attribute runs an automatic trimming of the log
file at the
defined time, regardless of the size. The format of the variable
is
HH:MM (hour:minute).
Default: undefined
How the trimming mechanism trims the log files differs depending on how you define
the log file size management attributes. The following table summarizes the trimming
behavior.
Table 153 Raw log file attributes that manage the log file trimming mechanism
When you do not configure runtime rollover l NetWorker checks the log file size when
by time or runtime rollover by size the nsrexecd process starts on the
computer.
l When the log file size exceeds the size
that is defined by the maximum size MB
attribute, NetWorker renames the
existing log file to
log_file_name_date_time.raw then
creates a new empty log file.
Table 153 Raw log file attributes that manage the log file trimming mechanism (continued)
Managing raw log file size for the daemon.raw, networkr.raw, and gstd.raw files
To configure the NetWorker software to rollover the .raw file by time, perform the
following steps.
Procedure
1. Log in to the NetWorker host with root on UNIX or Administrator on Windows.
2. To access the NSRLA database, use the nsradmin program:
nsradmin -p nsrexec
name: daemon.raw;
log path: \
"C:\\Program Files\\EMC NetWorker\\nsr\\logs\\daemon.raw";
5. Define the log resource that you want to edit:
6. Update the runtime rollover by time attribute with the time that you want to
rollover the log file.
For example, to configure the gstd.raw file to rollover at 12:34 AM, type:
troubleshoot mode. The nsrexecd process is the main process for NetWorker client
functions. To troubleshoot problems that are related to NetWorker client functions,
start the nsrexecd process in troubleshoot mode.
Procedure
1. Log in to the NetWorker host with the root account, and then stop the
NetWorker processes:
nsr_shutdown
2. From a command prompt , start the daemon, and then specify the troubleshoot
level.
For example:
l To start the nsrexecd daemon in troubleshoot mode, type:
Where filename is the name of the text file that NetWorker uses to store the
troubleshoot messages.
3. After you collect the necessary troubleshoot information, perform the following
steps:
a. Stop the NetWorker processes by using the nsr_shutdown command.
b. Restart the processes by using the NetWorker startup script:
l On Solaris and Linux, type:
/etc/init.d/networker start
l On HP-UX, type:
/sbin/init.d/networker start
l On AIX, type:
/etc/rc.nsr
c. Click Start.
4. To put the nsrd process in troubleshoot mode:
a. Right-click the NetWorker Backup and Recover service, and then select
Properties.
b. In the Startup Parameters field, type -D x.
where x is a number between 1 and 99.
c. Click Start.
Results
NetWorker stores the troubleshoot information in the daemon.raw file.
After you finish
After you capture the troubleshoot information, stop the NetWorker services, remove
the -D parameter, and then restart the services.
2. Edit the file and specify the following at beginning of the file:
GST_DEBUG=x
export GST_DEBUG
/etc/init.d/gst stop
then
/etc/init.d/gst start
l AIX: Type:
/etc/rc.gst start
then
/etc/rc.gst stop
Results
NMC stores the troubleshoot information in the gstd.raw file.
After you finish
After you capture the troubleshoot information, stop the gstd daemon, remove the
environment variable from the startup file, and then restart the gstd daemon.
where:
l PID is the process id of the process.
l x is a number between 0 and 9.
Note: 0 turns off troubleshoot.
Results
NetWorker logs the process troubleshoot information in the daemon.raw file.
After you finish
To turn off troubleshoot, type:
Procedure
1. From the Administration window, click Protection.
2. In the left navigation pane, click Clients.
3. Right-click the client, and then select Modify Client Properties.
4. On the Apps & Modules tab, in the Backup command attribute, type:
save -Dx
where:
l x is a number between 1 and 99.
l file_sytem_objects is the name of the files or directory to backup.
l filename is the name of the file that stores the troubleshoot information.
Note: The NetWorker Command Reference Guide provides detailed information
about all the available backup options and how to use the save command.
Procedure
1. On the Administration window, click Recover:
l To modify a scheduled recover job, select the job in the Configured
Recovers section, and then select Properties.
l To configure a new recover job, select New.
Note: You cannot modify an expired or failed to recover job.
2. To create or modify the recover job, use the Recovery wizard. On the Select
the Recovery Options window, select Advanced Options.
3. In the Debug level attribute, select a troubleshooting level between 0 and 9.
4. Complete the remaining steps in the Recovery Wizard.
Results
NetWorker logs the troubleshoot recovery information to the recover log file.
Running a recovery job in troubleshoot mode by using nsrtask
Use the nsrtask command to run a recovery job that is created by the Recovery
wizard, from a command prompt.
Procedure
1. On the NetWorker server, type: nsradmin.
2. From the nsradmin prompt:
a. Set the resource attribute to the Recover resource:
. type: nsr recover
b. Display the attributes for the Recover resource that you want to
troubleshoot:
print name:recover_resource_name
c. Make note of the values in the recover, recovery options, and recover
stdin attributes. For example:
recover command: recover;
recover options: -a -s nw_server.corp.com -c
mnd.corp.com -I - -i R;
recover stdin:
“<xml>
<browsetime>
May 30, 2013 4:49:57 PM GMT -0400
</browsetime>
<recoverpath>
C:
</recoverpath>
</xml>”;
where:
l nw_server.corp.com is the name of the NetWorker server.
l mnd.corp.com is the name of the source NetWorker client.
3. Confirm that the nsrd process can schedule the recover job:
d. When the recover command completes, review the recover output for
errors. If the recover command fails, then review the values that are
specified in the Recover resource for errors.
7. To review the details of the Recover job, use the jobquery command. From a
command prompt on the NetWorker server, type: jobquery
8. From the jobquery prompt, perform one of the following steps:
l Set the query to the Recovery resource and display the results of all
recovery jobs for a Recovery resource:
Where jobid is the jobid of the Recover job that you want to review.
Note: Review the daemon.raw file on the NetWorker server to obtain the
jobid for the recovery operation.
where:
l x is a number between 1 and 99.
l file_sytem_objects is the name of the files or directory to recover.
l filename is the name of the file that stores the troubleshoot information.

Deleting the NSR Peer Information resource by using nsradmin
To delete the NSR Peer Information resource for the initiating host, use the
nsradmin command on the target host.
Before you begin
Connect to the target host with an account that has administrator access to the
NSRLA database. You must configure access privileges to the NetWorker client
database.
Procedure
1. Connect to the nsrexec database:
nsradmin -p nsrexec
2. Set the query type to the NSR Peer Information resource of the initiating host:
show
4. Print the attributes for the NSR Peer Information resource and confirm that
the name and peer hostname attributes match the hostname of the initiating
host:
delete
quit
Results
The target host creates a new NSR Peer Information resource for the initiating host
the next time that the initiating host attempts to establish a connection with the
target host.
Backups fail to start when the daylight savings time change occurs
When you schedule backup operations to occur during the hour in which the operating
system moves the clock ahead or behind by one hour, NetWorker skips the backup
operation. For example, the operating system is configured to move the clock forward
one hour at precisely 2:00 A.M. and backups are scheduled to occur at 2:01 A.M. At
2:00 A.M., the operating system moves the clock forward to 3:00 A.M. NetWorker will
skip all backup operations that are scheduled to start between 2:01 to 2:59 and
NetWorker does not initiate the backup operation.
To avoid this situation, set the backup time to occur at least one minute before the
time change occurs.
Note: When you use the mminfo command to get a weekly save set usage
summary for the time period during the change to daylight savings time, mminfo
does not display any information for the day of the change.
Clone ID timestamp does not reflect the time the clone was created
To guarantee that the cloned save sets that NetWorker creates on different storage
nodes do not have the same timestamp, the NetWorker software assigns a timestamp
to cloned save sets that does not reflect the actual time that NetWorker creates the
clone.
If the server can find the correct position, media verification succeeds and a
successful completion message appears:
media info: verification of volume "jupiter.007" volid 30052
succeeded.
If this message appears, specify a block size that is greater than or equal to 32.
To resolve this issue, ensure that you recover indexes to the original location then
move the indexes to another directory. Moving a client file index describes how to
move indexes to another directory.
The updated entry, with a desktop heap allocation of 1024 KB appears as:
%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows

ServerDll=basesrv,1
ServerDll=winsrv:UserServerDllInitialization,3
ServerDll=winsrv:ConServerDllInitialization,2
ProfileControl=Off
MaxRequestThreads=16
4. Restart the NetWorker server.
The Microsoft Knowledge Base article 18480 on the Microsoft website provides more
information.
Hostname aliases
When you incorrectly define an alias for a client, the backup fails. Under certain
conditions, such as improperly configured DNS servers or hosts files, the NetWorker
software does not create any aliases for a new client. If you use TCP/IP, ensure that
you specify the hostname and the fully qualified domain name (FQDN) for a client in
Aliases field of the client properties window.
When the alias field is incorrectly defined you can see the following behavior:
l Backup operations for the client fail with the following error message:
No Client resource for client_name
l NetWorker always performs backups for a client at a level full, regardless of the
level of the scheduled backup.
l Automatic index management, as set up in the browse and retention policies, does
not work.
l The /nsr/index directory, which contains the indexes for all the clients that are
configured on the NetWorker server contains two directories for the same client,
but each directory uses a different client name.
You must update the alias field for a client to include all hosts names for the client in
the following situations:
l When a host have two or more network interfaces.
l When sites use a mixture of short and FQDNs for the same servers, for example,
mars and mars.jupiter.com.
l When the datazone uses both (Network Information Services (NIS) and DNS.
NOTICE Do not include aliases that are shared by other hosts in the datazone.
This message indicates that NetWorker has not previously performed a back up of the
specified save set. Before you can perform an incremental or level backup on a save
set, perform a full backup of the save set.
If a level full backup exists for this save set, this error message can appear in the
following situations:
l The clocks on the client and server are not synchronized.
l The savegrp session begins before midnight and ends after midnight.
l Multiple client ids exist for the client.
To resolve this issue, use the nsrck -L2 clientname to create a client file index for
the client, then try the scanner command again.
nsrck -L5
If the command does not resolve the index corruption, refer to Adding information
about recyclable save sets to the client file index on page 553 for more information.
Aborting a recovery
When you stop a recovery operation on a client, the following could occur:
l The recovery might stop immediately.
l The recover program will display a list of the files that were not recovered.
l Messages similar to the following appears, which indicates that the recovery
operation did not stop cleanly:
Recover: ***Canceled***
Recover: Unable to read checksum from save stream
Recover: error recovering C:\WINDOWS\CURSORS\APPSTART.ANI
Didn't recover requested file C:\WINDOWS\CURSORS
\APPSTART.ANI
determines when the backup operation should include a drive. If more than one local
drive uses the same serial number, the All save set will only back up one of the drives.
To resolve this issue, perform one of the following solutions:
l Use the DiskProbe utility to set the serial numbers to unique numbers. The
DiskProbe utility is part of the Windows Support Tools and is available for all
versions of Windows supported by NetWorker software.
l Avoid using the All save set. Instead, specify each drive letter or the VSS SYSTEM
save set separately. The DISASTER_RECOVERY:\ save set on page 425 provides
more information about the All save set.
To workaround this issue, use the cp command to copy the file after recovery:
cp recovered_filename zero_filled_filename
This can occur when the backup operation does not write any data to the backup
media during the compression operation and time the backup is idle reaches the time
that is specified by the group Inactivity Timeout attribute. To resolve this issue,
increase the Inactivity Timeout attribute for the backup group.
To help determine an adequate timeout limit:
1. Set the Inactivity Timeout value to zero. A value of zero results in no timeout
limit.
2. Determine the time that the backup requires to complete a full save of the file
system, and specify this time as the inactivity timeout limit.
mminfo -N C:\
Successful save sets listed as failed in the Group Backup Details window
Certain backup operations, such as on some NetWorker modules, create multiple
sessions to perform a single backup job. If one of these sessions fails, the Console
reports that the entire backup job has failed.
To determine the status of each session, click the Show Messages button in the
Failed table of the Savegroup Completion dialog box. This information also appear in
the Logs tab, under monitoring, and in the savegroup completion report.
To resolve the issue, ensure that the backup start time of the virtual server and the
physical node is different.

This can occur if RPC communication with the RabbitMQ server fails because of
missing exchanges such as amq.direct, amq.fanout, amq.headers, amq.match, and so
on.
To resolve the issue, do the following:
1. Shutdown NetWorker.
2. From the command prompt, type the following command to go to the directory
that contains the RabbitMQ files:
l Windows: cd C:\Windows\system32\config\systemprofile\AppData
\Roaming
l Linux: /opt/nsr/rabbitmq-server-3.2.4/var
3. Type ren RabbitMQ RabbitMQ.v01 to save the existing RabbitMQ directory.
4. Start NetWorker.
After NetWorker starts, new RabbitMQ files are created.
l Windows: C:\Windows\system32\config\systemprofile\AppData
\Roaming\RabbitMQ
l Linux: /opt/nsr/rabbitmq-server-3.2.4/var
To verify if the missing exchanges are present, run the following commands:
Windows:
% set ERLANG_HOME=C:\PROGRA~1\EMCNET~1\nsr\rabbitmq-server-3.2.4
% set HOMEPATH=\Windows
% rabbitmqctl report
Linux:
# HOME=/nsr/rabbitmq /opt/nsr/rabbitmq-server-3.2.4/sbin/
rabbitmqctl report
This error is resolved automatically after about an hour. There is no action required
from the user.
Ignore the message, and continue to add the client to the UNIX server. To avoid the
message, add the UNIX server hostname to the servers file on the client after you
add the client to the UNIX server.
To resolve this issue, add all of the server aliases that are related to any additional
network interfaces to the alias list of Client resource for the NetWorker server.
The following users have permission to recover any files on any client, regardless of
the users who are listed in the Remote Access attribute:
l ‘Root’ user on a UNIX host
l Member of the ‘Administrators’ local group on a Windows host
l Members of a ‘Application Administrator’ User group on the NetWorker Server
l Members of a NetWorker Server User group that has the ‘Change Security
Settings’ privilege
Other users can only recover files for which they have read permission, which is based
on file permissions at the time of backup. Files recovered by a user other than root,
operator, or the operator group are owned by that user.
These messages indicate that one or more NetWorker services are not running on the
NetWorker server. The following table summarizes the startup commands that you
can use to startup the services on a UNIX NetWorker server.

When DCC identifies any unreachable device due to various reasons, it moves the
device to suspected state and it sets two attributes Suspected device and Suspected
mark time.
l Suspected device and suspect time attributes are set when the device state is
changed to suspected state from normal state and these attributes are cleared
when the device is available.
l If there is any device that is in suspected state and is moved to service mode
manually, suspected flag is cleared off and there won't be any DCC check on that
going forward. DCC starts checking this device only if it again moves to enabled
state.
