Backing up my system

Recently I bought a Creative mp3 player, but last time I got my computer redone the guy who did it didn't put windows xp back in. The mp3 needs windows xp for it to be compatable, and I was wondering if i could install it myself?

I know i would have to back up all the information on my computer, but im not sure how to do any of that..could you give me a quick idea about how i could do it so i can save a few hundred bucks. thanks so much !

anyone?

Multiple ways, dependant on how large the quantity of data you require to back up.



Either a USB flash key

External USB HDD

Additonal HDD as a slave

Via the internet to a another PC or server

Floppy disk

CD/DVD disk
