I set this up to backup my Macbook. I setup a RAID 1 mirror on two external USB drives on a Mac Mini, shared the drive, and I back up to it as a time capsule using this trick: http://www.readynas.com/?p=253 http://www.readynas.com/?p=253 Then I ran a nightly backup of that volume to Jungledisk. It was very emotionally satisfying. Unfortunately my up tube is too small, and the data won't fit. The initial 100GB upload was gonna take 40 days, so I stopped it after 10 with slow internets. If you have the tubes, I do recommend it though. Its a really solid backup setup.
