Backup scripts

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/. Also recommend the article DAR differential backup mini-howto.

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

MAILTO may also be used to direct mail to multiple recipients by separating recipient users with a comma.
