yeah, a lot of games are dvd based so you can just copy them to your hard drive, and burn them to an empty dvd, the only problem is, you have to have a ps2 with a mod chip in it to play the backed up games. there is a program you can buy that lets you load games onto a hard drive that you can connect to the network adapter (provided you have a network adapter) and you can play the games straight off the hard drive, that is a way you could back up your games.
