If [!-d "$path"]; then

Mkdir-p "$path"

Fi

# back up and log the backup

Xtrabackup-- backup--user=root-- host 172.30.249.57-- password $paw-- datadir=/data/DB/mysql-- target-dir=$path/backup-$ (date +% Y%m%d) > / backup/mysql/ `date +'% Y% m% d'` _ backup.log 2 > & 1

# Delete backups from 7 days ago

Find / backup/mysql-ctime + 7-exec rm-rf {}\

Echo "complete backup"

Then use crontab to execute it regularly.
