Ah, but think what I've learnt...

My *real* data gets backed up with rsnapshot, a totally awesome little 
shell script that basically replicates Apple's Time Machine --- it does 
daily/weekly/monthly backups using hardlinks so that it only uses disk 
space for changed files. The backups themselves are just directory trees 
so getting individual files back is trivial. It'll even push or pull 
ssh, so it's easy to set it up to do offsite backups. Set it up once and 
never touch it again, until something goes wrong; very cool.

Out of interest, is it possible to get external HDD racks? Just a box 
with cooling and power, out of which I can run a bundle of SATA cables 
to the PC. And, preferably, not industrial sized, too.
