You are using a single drive, with no RAID, for storing the backup
files? You are more brave than I am, if that is an IDE disk.
I was wondering what are the options to be able to make this scalable,
how do backuppc boxes work together,
Well, if you don't mind different clients on different servers, they
work without knowledge of the other.
are virtual file systems (such as CODA) a good idea and so on.
Not really, no. I wouldn't trust a network file system other than NFS,
and NFS was ... a bad idea, in terms of performance, when I tested it
locally.
Using LVM or software RAID to get larger capacity in a single machine
has already been suggested, and is probably your best bet.
Personally, I would suggest using some sort of RAID underlying the
backup storage space, such as RAID-5, RAID-6 or RAID-1 (or LVM) on
RAID-0.
Any of those will give you a higher capacity than a single drive can
allow for, as well as allowing you to tolerate at least a single disk
failure without all your backups being lost.
