What about Amazon S3 and winrar or winzip (Score 1)

Since you are storing so little data, I would suggest you open an account with Amazon S3 and let them worry about the storage (combine that with Jungle Drive and Novell netdrive to create a pseudo network drive on your machine - both software are a snap to setup). Then you grab your favorite winrar, winzip, archive program, and you RTFM (many people find software "hard to use" but they don't even bother learning how to use them). You schedule an archive update every week and you're done. Works great for me. I backup all my important files (pr0n and MP3 don't count) to an S3 container and I am happy as can be.
