Description
明 細 書 リモー卜バックアップシステム 技術分野 Description Remote backup system Technical field
本発明は、 リモートバックアップシステムに関し、 詳しくは地球規模で構築し たセキュリティネットワークを利用すると共にバックアップデータをスイス国に 設置したシステムに蓄積するようにしたリモ一卜バックァップシステムに関する < 背景技術 The present invention relates to a remote backup system, and more particularly to a remote backup system that uses a security network constructed on a global scale and stores backup data in a system installed in Switzerland.
従来技術におけるデータバックアップにおいて、 現在の殆どの企業は様々なデ ータをデジタル化して保存している。 デジタル化により、 今まで書類保存のため にさいていたスペースの有効活用、 整理のための時間の有効活用等、 様々な効率 アップが実現している。 しかしデジタル化というのは便利さがある反面、 全て電 気の力に頼っているという弱点を持っている。 極端な話、 データの保存中に不意 の停電が起きれば、そのデータ自体どうなるか解らない。そこで、各企業は、様々 な光ディスク等の記録媒体にバックアップを取って自衛しているのが現状である さて、 上記のように記録媒体、 例えばディスクに保存したデータであっても、 もし火事、 地震等の天災に遭遇した場合には、 保存したディスク自体が損壊する ことになリ、 その保存されているデータ自体もダメージを蒙ることになる。 In the data backup of the conventional technology, most companies digitize and store various data. Digitalization has achieved various improvements in efficiency, such as the effective use of space previously used for storing documents and the effective use of time for organizing documents. However, while digitalization is convenient, it has the disadvantage of relying entirely on the power of electricity. In extreme cases, if an unexpected power outage occurs while data is being stored, it is not clear what the data itself will be. Therefore, at present, each company is backing up on various recording media such as optical discs to protect itself. Even if the data stored on the recording media, for example, discs as described above, If a natural disaster such as an earthquake is encountered, the stored disk itself will be damaged, and the stored data itself will be damaged.
このような不慮の災害を防止するために、 現在のシステムとは別の場所にバッ クアップすることを専門に行う企業等が出現し、 その企業はシステムの生データ をミーラーコピーしてバックアップする、 所謂、 ミラー機能を備えたサーバによ つて構築されているものが周知である。 In order to prevent such unforeseen disasters, companies have emerged that specialize in backing up to a location different from the current system, and that company backs up the raw data of the system by mirror copy. It is well known that the server is constructed by a server having a so-called mirror function.
しかしながら、 従来技術で説明したように、 バックアップ体制においては、 バ ックアップするデータと同一国、 例えば、 曰本国であれば、 日本国内において、
地震等の発生しない地理的条件を算出すると共に電源供給が安定している地域を 特定してバックアップシステムを構築しているのであって、 地震国とか電源事情 が悪い国等の国の政策で解決しなければならない環境条件を有する国においては、 基本的にバックアップ体制をとリずらく、 その結果、 過去の地震データ及び現在 の地震が発生しずいらい地域であって、 且つ電源事情がよい地域を選んでバック アップシステムを構築している。 However, as explained in the prior art, in the backup system, the data to be backed up is in the same country as the data to be backed up, for example, It calculates geographical conditions that will not cause an earthquake, etc., and establishes a backup system by identifying areas where power supply is stable.This is to be resolved by policies of countries such as earthquake countries or countries with poor power supply conditions. In countries where there are environmental conditions that must be met, a backup system is basically hampered. As a result, areas where past earthquake data and current earthquakes are difficult to generate and where power supply conditions are good To build a backup system.
又、 バックアップするために、 バックアップシステム自体を分散して危険を回避 するようにしたシステムも実現している。 In addition, a system has been implemented in which the backup system itself is distributed to avoid dangers for backup.
しかし、 上記いずれの方法においても、 国内で発生したデータは国内で処理する 観点から種々の手法をとつているが、 天災等に対処するすべがなく、 また、 国を 単位とした解決がなされておらず、 根本的な解決策にはなっていないという問題 がある。 However, in all of the above methods, various methods are used from the viewpoint of processing data generated in Japan from the viewpoint of domestic processing.However, there is no way to deal with natural disasters, etc., and solutions have been made on a national basis. There is a problem that it is not a fundamental solution.
従って、 データをバックアップするシステムにおいて、 天災による災害が少な く且つ電源事情が国単位で良好な、 例えば、 スイス国等に世界規模のバックアツ プ体制ができるバックアップシステムに解決しなければならない課題を有する。 発明の開示 Therefore, there is a problem in the data backup system that there is little natural disaster and the power supply situation is good on a country-by-country basis, for example, a backup system that can provide a global backup system in Switzerland and other countries. .
