Might also consider dropbox if you have less than 2GB, and you want to have the files automatically synched between all of your computers. I use it for all of my lawschool notes. It backs everything up automatically, and it also automatically downloads everything from my laptop to my desktop, so I can pick right up where I left off.
Edit:
2GB is free, you can get 50gb for $10/mo and 100gb for $20/mo
