Here, We are going to use a 'vzbackup.sh' bash script to schedule backups. You may customize this script according to you needs. You may schedule backup on remote server or on the same node. For this you need to edit 'vzbackup.sh' script. Steps to schedule backup is are as follows,

1. Make passwordless login enabled to backup server from openvz server.

2. vzdump, scp, rsync and crontab must be running/installed on OpenVZ server.

3. Copy, Edit and set execute permissions to backup script:

    ]# cp -rvp /media/pendrive/vzbackup.sh /vz/backup/
    ]# vi /vz/backup/vzbackup.sh
        [EDIT]
    ]# chmod +x /vz/backup/vzbackup.sh

4. Schedule regular backup through crontab command:

    ]# crontab -e
       41 21 * * * /vz/backup/vzbackup.sh >/dev/null 2>&1

    ]# crontab -l  (Crontab File : /var/spool/cron/root)

    ]# service crond restart
