System restore can be pretty evil. The first thing I do is turn it off. Not only does it steal disk space and affect performance (disk i/o is among the most time-consuming operations), but it will happily back up viruses. Everytime someone's called me over to fix a virus, the virus kept coming back, until I realized it was living it up in the system restore area as well.

If you don't have anything important to back up, no reason to bother... if you do, you should do it properly (at least burn a CD or scp it to another system).
