backup program

[advan]

Btw, I thought about backing up the system drive (C drive) as Broni mentioned and am doing it now. As I haven't installed any backup software yet, I used the program in XP (Accessories> Backup) and as it is in the process of backing up now, creating a .bkf , I wonder how do I use this? There was an option at the start of a.) backup files and b.) restore backup files. Though I'm using option A now, obviously, when my PC crashes and I'd have to use my backup files, I'll use option B. But to reach this program that restores, I'd have to have XP re-installed in the reformatted pc? Or do I copy paste this backup file to the clean slate C drive and it's good to go?

Will it also work if I just copy paste the entire C drive to make my backup copy?
