We're running out of space in the vg.

The only feasible place for rsync backups is treehouse because it's
local. I will add two more hard drives as soon as I visit the co-lo.
Alternatively, we could start using the FSF backup server which has an
impressive amount of storage:

 Filesystem            Size  Used Avail Use% Mounted on
 /dev/md4              2.7T  2.3T  334G  88% /srv/md4
 /dev/md5              2.7T  2.3T  292G  89% /srv/md5
 /dev/md6              2.7T  1.6T  961G  64% /srv/md6
 /dev/md7              2.7T  2.5T   60G  98% /srv/md7

Meanwhile, we could exclude /var/lib/mysql from the backup: the ibdata
file is a gigantic blob of 4GB that changes a little bit every day.

We're already taking a daily dump, although there's no history.

No, because they're not being hosted locally. We don't need more
servers, we just need more disk space :-)
