The whole drive (say, the full 100 Gb) each time (an 'image')?
Or individually changed files? Only your own documents/music/photo's? How often?
In other words: tell your planned backup strategy.
I am able to back up my drive on floppies only for some reason with the utility that came with XP Pro. is there a better and easy back up progrm out there that will let me back up my drive to dvd's?
