rsync によるディスクのフルバックアップ
1 スクリプトの作成
[/usr/local/sbin/daily-backup]
rsync -xa --delete --exclude={'/500g/','/2000g/'} / /500g/backup-125g
rsync -xa --delete /500g /2000g/backup-500g
実行権限の付与
chmod a+x /usr/local/sbin/daily-backup
2 クーロンの設置
[/etc/crontab]
# /etc/crontab: system-wide crontab # Unlike any other crontab you don't have to run the `crontab' # command to install the new version when you edit this file # and files in /etc/cron.d. These files also have username fields, # that none of the other crontabs do.
