    mount \
    rsync \
    openssh-server \

### Cron job for incremental backups

Edit the root crontab

~~~
# $editor /etc/cron.d/bkctld
+ MAILTO=alert4@evolix.net
+ 30 11 * * * root /usr/sbin/bkctld inc && /usr/sbin/bkctld rm
+ 30 23 * * * root /usr/share/scripts/check-incs.sh 1> /dev/null
~~~

## Notes
If you want mutiples backups in a day (1 per hour maximum) you can
run `bkctld inc` multiples times, if you want to keep incremental
backups **for ever**, just don't run `bkctld rm`.
