Update to the backup situation: I've found the "flickr of everything else" in a company called carbonite.com. Their site and UI is a litte shall we say unpolished but over all it looks like a good service. It's only $5 per month for unlimited storage, but the problem is they only allow stuff that sits on the C drive. So here's my plan:

Build a Cheap and Fast RAID 5 NAS | Tom's Networking

Yep, I'm going to build a RAID 5 server that has about 500GB total storage. Then I'm going to use the server as THE Carbonite backup machine for my digital bits and gibbles. I figure it like this: everything goes to the backup server and the backup server has a C drive tha is a RAID 5 and connects to carbonite....

Hmmm...sounds a little too elaborate, right? Yeah...it is. But it may the good way to go until I can find the perfect storm of non-photo file backup solutions
