A while back I asked for suggestions on how to use 4 500GB drives to build a backup machine. It took me a while, but two weeks ago I started to build up that system, and the first thing I discovered was that the drives were SATA but the old Dell box wasn't. I started to hunt around for a SATA box I could buy when it dawned on me that I was building a centralized backup system for the house. Centralized. As in a single point of failure. Which, when you put it that way, didn't sound like such a bright idea. So instead I opted for a distributed system; I ordered some USB enclosures, now each machine has it's own independent 500GB backup drive attached. The upside, besides being cheaper and easier to implement, is that offsite storage is also going to be a lot easier now.
