A good friend of mine, Josh Clark, spoke about free file backup services with a company called Mozy.

For your personal computer, you can back up your data on an online file server and forget about worrying about backing up your files; we’ve all had a computer crash and lost data that was precious and sometimes had no way to recover it; using multiple methods of backup prevents this from happening. (It has both Macintosh and Windows programs.)
