Abstract

For several years I have been teaching a file updating algorithm which is essentially the same as that in Dwyer's admirable paper [1]. There is one unjustified objection to the algorithm that perceptive students and people with batch processing experience almost invariably raise and which is not addressed by Dwyer. The objection is based on a situation which arises in a batch processing environment with several users, where key-ordered sequential update is used.

Optimization of large sequential data files
ACM '77: Proceedings of the 1977 annual conference

The need for inexpensive data storage continues to grow and tape reels are usually used. For large data aggregations with even a few retrieval applications, it may not be as economical to store full reels as to split the data into smaller sized files. ...
One big file is not enough: a critical evaluation of the dominant free-space sanitization technique
PET'06: Proceedings of the 6th international conference on Privacy Enhancing Technologies

Many of today's privacy-preserving tools create a big file that fills up a hard drive or USB storage device in an effort to overwrite all of the “deleted files” that the media contain. But while this technique is widespread, it is largely unvalidated.

Implementation of a stackable file system for real-time network backup

We propose a backup system based on a stackable mirroring file system, general-purpose mirroring file system (GMFS). This file system mirrors data in real-time on the file system layer. It uses the typical network file system (NFS) and backs up data to ...
