マウントされているがアンマウントしたくない業務ボリュームに対しては、101〜110行目、113、146行目(物理ボリュームの場合)または163〜172行目(ボリュームグループの場合)のコメント(“#”)をエディタ等で消去し、101行目または163行目のif文で対象となるデバイスを指示してください。なお、108行目または169行目のsyncコマンドを実施してからバックアップ後処理を実施するまでの間は、業務ボリュームのファイルシステム更新操作を行わないようにしてください。もし、この間にファイルシステム更新操作が行われると、ファイルシステムが不完全な状態でバックアップが採取されるか、またはバックアップ後処理で実施するfsckコマンドがエラーとなる可能性があります。
