A full backup with the following excluded/included: include /var/lib/vservers/bart/chroot/db/dumps/savannah.sql exclude /sys exclude /proc exclude /var/lib/vservers/bart/chroot/db/var/lib/mysql/savannah exclude /var/lib/vservers/*/var/log exclude /var/lib/vservers/*/var/log.l exclude /var/lib/vservers/*/chroot/*/var/log exclude /var/lib/vservers/*/chroot/*/var/log.l exclude /var/lib/vservers/bart/chroot/db/dumps.l exclude /var/lib/vservers/bart/chroot/db/dumps meaning we can expect 2GB per day.
