Crontab
Here is a sample script to use for backups. It backups each day at midnight for a week only. A cron job entry is added to the root crontab to run the script at midnight each day. To add the script to the root crontab type the following as the root user: crontab -e

@midnight   /usr/local/bin/backup.sh Save and exit the crontab editor.

Invoke Local Manual Backup
After you have completed the above, you can start a backup anytime by typing the following as the root user: /usr/local/bin/backup.sh Then check the files in the backup folder by typing the following: ls -lh /var/backup
