These backup scripts use rsync to minimize network load and creates incremental backups, preserving last four backups. For more info, read http://www.mikerubel.org/computers/rsync_snapshots/.
To install the cron job, run:
$ sudo crontab -e
And add these lines according to your personal configuration:
MAILTO=nomail@openkm.com
@weekly /root/backup.sh | tee -a /root/backup.log
Or, if you want to separate log reports by date:
MAILTO=nomail@openkm.com
@weekly /root/backup.sh | tee /root/backup.$(date +\%Y.\%m.\%d_\%H.\%M.\%S).log
