rdiff-backupを使った過去のデータの復元
まずは-lオプションで履歴を確認してから期日を指定しています。Gitより直感的でわかりやすいです。
こんな感じです。
ak@ak-Prime-Series:~/tmp/t % rdiff-backup -l /var/backup/aaa/ Found 3 increments: increments.2012-06-09T13:08:16+09:00.dir Sat Jun 9 13:08:16 2012 increments.2012-06-09T13:25:16+09:00.dir Sat Jun 9 13:25:16 2012 increments.2012-06-09T13:32:05+09:00.dir Sat Jun 9 13:32:05 2012 Current mirror: Sun Jun 10 11:59:47 2012 ak@ak-Prime-Series:~/tmp/t % ls ak@ak-Prime-Series:~/tmp/t % rdiff-backup -r 2012-06-09T13:25:16+09:00 /var/backup/aaa/ ./ ak@ak-Prime-Series:~/tmp/t % ls H04-04-04_勾留状.jpg h-twit-Diary.rb~ twilog-f-url.sh~ yahoo-mai-rb.txt H18_最高検察庁からの書面 no-follower.rb~ wordpress-img-a-link.sh h-blogger-rss.rb~ twilog-f-date.sh~ wordpress-img-a-link.sh~ ak@ak-Prime-Series:~/tmp/t %
rdiff-backup -r 2012-06-09T13:25:16+09:00 /var/backup/aaa/ ./
が肝の部分です。
この場合、/var/backup/aaa/rdiff-backup-dataというディレクトリの中身を見ただけでもだいたいのことがわかります。/var/backup/aaaディレクトリの中のrdiff-backup-dataディレクトリ以外が、最新版の内容みたいです。テスト用なのでファイルの数も少ないですが、バックアップ用の沢山のファイルが作られているのがわかります。最初がフルバックアップで、あとは差分の追加や削除という扱いみたいです。
