Help! How do I back up the system ???

[Sabi]

Hi guys;

I have downloaded Window XP Service Pack 2 Set up 20 minutes ago. I am about to install it. However the Wizard is recommending that I back up my system!:smileysad:

How do I do that? I have crashed my laptop through the same thing with WXP Service Pack 2 in November 04. I don't want the same thing happen again, so please please help

Thank you
Sabi
