you can use a program like ghost or clonezilla and it will make an image of your computer and save it to a dvd or something.
clonezilla are we talking about? It doesnt look like clonezilla will burn to a cd/dvd natively there is a tweak to do... but it will go directly to a hard drive.
then when you want to restore you will boot back up to the cd and choose restore and pick your image.

i pulled that from clonezillas site
Ghost is much easier to use and very reliable for a symantec product... they do have a few good programs. but it isnt free.
