Software to Copy a Xbox 360 Game?

I was reading through the terms and conditions in the manual of a xbox 360 game i have and i came across a part that basically says you can make one copy for your (and only your) personal use. so it is beyond a doubt legal, but thats not the point… what is a xbox 360 game copy software and what might it cost? thanks!

There is none. Also, even if XBOX'S terms allow it, the game itself's might not. They say "do not copy this disk" at the start
