I have a 1.5TB USB drive that is my repo server, archiver and backup on 
my Amahi server with a 120Gb drive.

I am right now pricing out a 2TB USB drive ($80 on ecost) to put on 
another server for backing up the backup. I figure that will give me 
enough total redundancy to survive most disasters. This drive will only 
be used for a weekly backup and the rest of the time be kept in a firebox...
