5.4 Post script example (Linux Shell Script)

#!/bin/bash
#发送通知邮件
echo "Backup has completed" | mail -s "Backup Notification" [email protected]

#清理临时文件
rm -rf /backup/tmp/*

#恢复相关服务
service myapp start

#验证备份文件
if [ -f /backup/backupfile.tar.gz ]; then
    echo "Backup file exists" | mail -s "Backup Success" [email protected]
else
    echo "Backup file is missing" | mail -s "Backup Failure" [email protected]
fi

Pre- and post-scripts provide great flexibility and automation in backup strategy, ensuring efficient backup process and data consistency. By using pre- and post-scripts, administrators can prepare before backup starts and perform subsequent processing after backup is completed, ensuring the smooth progress of the backup process.

Please note that before and after scripts can be used not only during the backup process, but also during the recovery process.
