Abstract To allow for securing backup data of the maximum number of generations to be held even when backup data is locked.SOLUTION: When inhibition of overwriting one or more storage regions 51 is locked, a backup server 14 prepares a new backup management table 504, and stores backup data of the maximum number of generations to be held in a storage system 11 using the backup management table 504 and an archive management table 503, which is the past backup management table 504.SELECTED DRAWING: Figure 1 【課題】バックアップデータがロックされた場合でも、最大保持世代数分のバックアップデータを確保することを可能にする。【解決手段】バックアップサーバ１４は、１以上の格納領域５１に対して上書きを禁止するロックが行われた場合、新しいバックアップ管理テーブル５０４を用意し、バックアップ管理テーブル５０４と、過去のバックアップ管理テーブル５０４であるアーカイブ管理テーブル５０３とを用いて、最大保持世代数分のバックアップデータをストレージシステム１１に格納する。【選択図】図１
