How the Hell do you......

Help! I just got a new external cdrw - Qtech/quantum ide-cdr\rw8x4x32 . I am new at this and dont have a clue how to backup any games. It came with Nero 5.0 and i just dont know where to start or what options to select, nevermind what the hell they mean! This is mainly to backup my PSx and PC games.

Any help at all would be Supremely Appreciated!!!!!
