Small? I thought that I worked for a small company, and I'm going to need to
back up 2TB every week =-P Still, though, if you're only backing up 700MB
then you're probably missing quite a bit of data, not to mention whether you
want to back up your os, applications, etc. With 80GB, 100GB, or more per
desktop you're pretty much guaranteed to need more than that.

I haven't bought one yet, but I've heard many good things about LTO Ultrium
from IBM, HP, Dell, etc. The 2nd generation tapes which are just appearing
hold 200GB native, 400GB compressed, the tapes stream at 15-30MB / sec
(probably more for the 2nd-generation drives?) and drives cost maybe 5k or
so. I have my sights set on an autoloader, like the one from Dell that can
hold 14 tapes and 1-2 drives. Somewhere around 10k, I think.
Can anyone here personally vouch for using any of these guys?
