After create backup file there will be alot of files created in our backup folder.
So we need an auto delete old backup files.

1. Create recycle.sh

$ mcedit /recycle.sh

File content :

#! /bin/sh
find /backup | grep `date -d '1 week ago' +%Y-%m-%d` | xargs --no-run-if-empty rm

2. Edit crontab

$ mcedit /etc/crontab

File Content :

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

# run-parts
00 15 * * 1-6 root /bin/sh /recycle.sh

3. Reconfigure your crontab

$ crontab -u[username] /etc/crontab
$ crontab -l

Auto delete scheduled every Monday through Friday 2 pm :)
