It´s always a good idea to backup your hard drive(s) every now and then to prevent data loss. The guys, eh Gina, over at lifehacker wrote a nice article. It only describes the procedure for windows computers, all you need is an external hard drive, a ftp server and the freeware tool Syncback.
Everything is described in detail and easy to follow. Worth a look if you have sensible data or fear data loss.
