If you're looking for a backup solution that's basically set-it-and-forget-it easy, it's hard to go wrong with Data Robotics' Drobo. You can simply plug in your hard drive size of choice to the Drobo, back up all your important files on to it and it keeps your data safe. There are some cons to it though as you need to connect to one computer, and that doesn’t work as well in today’s environment of home and office network drives.
