Anacronジョブを手動で実行する


11

システムの最小限のインストールを実行しました。このシステムをPLEXメディアサーバーとして使用したい。LXDEは軽量のGUIなので構成しました。rsnapshotを使用して自動バックアップを実行するようにシステムを構成しています。rsnapshot.confファイルの構成に成功しました。ターミナルでrsnapshot weeklyコマンドを実行することで、目的の結果が得られます。

これが私のrsnapshot.confファイルです:

logfile /media/siddharth/Backup/Backup/Logs/Snapshot.log

# If enabled, rsnapshot will write a lockfile to prevent two instances
# from running simultaneously (and messing up the snapshot_root).

# writable. Otherwise anyone can prevent the program from running.
#
lockfile    /var/run/rsnapshot.pid

Anacronがこのジョブをエラーなしで実行するかどうかをテストする方法を教えてください。

ほとんどの場合、ログインできません。Anacronのテストを実行するにはどうすればよいですか。

タイムスタンプを無視して、anacronジョブを「強制実行」できます。

anacron -f

-n必要に応じて、などの他のオプションも使用できます。

からman anacron

 -f     Force execution of the jobs, ignoring the timestamps.

 -s     Serialize  execution  of jobs.  Anacron will not start a new job
              before the previous one finished.

 -n     Run  jobs  now.   Ignore  the  delay   specifications   in   the
              /etc/anacrontab file.  This options implies -s.

ログはで確認できます/var/log/syslog

各ジョブのタイムスタンプはに保存され/var/spool/anacronます。


よろしくお願いします!それは完璧です。期待どおりにバックアップジョブを実行できます。この回答が、WindowsからUbuntuに移行する私のような他の人々の助けになることを願っています。

PS:別の質問:24時間年中無休で実行される予定のないPCで毎週ジョブをスケジュールするには、cronまたはanacronを使用する必要がありますか?
