[Bacula-users] Capacity planning

[G. A. V. H. <va...@wh...>]

I've finally decided that I need to do something about network backup.
I've been incredibly lucky, but I'm old enough to realize that probably
won't last forever. Bacula looks like the way to go, so I'm diving in.

I picked up a pair of DLT7000 drives off eBay, and went diving in the
boneyard for parts. It looks like I've got an Adaptec 29160 to drive the
tape drives and a 36GB hard drive, an Athlon (around 2GHz), a half gig
of RAM, and a surprisingly clean case big enough to hold it all. (Alas, 
I blew out the power supply during Fedora Core 5 installation, larger PS 
arrives tomorrow for the next try.)

I mention this because I didn't find anything related to capacity issues
on the bacula.org website. I'll want to backup my own stuff (two
smallish servers, my XP machine, two Macs), my web servers, and then
I've got some clients who would really enjoy having their systems backed
up remotely. Is my proposed hardware a laughable toy? Or can I really
accomplish a fair amount with this, and presumably move to a loader when
the volume requires it?

Also, I'm no expert but I'm under the impression that PostgreSQL is the
more robust option for a database, and this is definitely a case where
reliability is more important than speed. Is there a significant and
specific advantage of PostgreSQL or MySQL in this project?
