# Install

A Debian package is available in the Evolix repository

~~~
echo "http://pub.evolix.net/jessie/" >> /etc/apt/sources.list
apt update
apt install bkctld
~~~

Then edit `/etc//bkctld`

## Chroot dependencies

The chroot jails depend on these packages

~~~
apt install \
    bash \
    coreutils \
    sed \
    dash \
    mount \
    rsync \
    openssh-server \
    openssh-sftp-server \
    libc6-i386 \
    libc6
~~~

## Client dependencies

The clients only require OpenSSH and rsync.

### 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 by hour maximum) you can
run `bkctld inc` multiples times, if you want to keep incremental
backups **for ever**, just don't run `bkctld rm`.
