Does anyone have any good tips on how to back stuff up and what to back up? I don't want to buy any new hardware or anything like that but I do have a CD-RW, DVD-RW & Spare PC with HDD.

I've never really backed up much, apart from saving two copies for important stuff and maybe dated backups too. The problem with that is that its always been on the same HDD which would seem rather silly if say the HDD crashed.

My PC that I use most has two HDD one ATA (80GB) & one S-ATA (160GB). My other (spare) PC has I think a 80GB ATA HDD which I guess I could backup things onto it but I would need to clean up all the stuff on there at the moment.

Anyone have any suggestions? Like do you think its worth me buying some DVD-RWs so I can't use them to backup onto? mind they are rather expensive arn't they? And does anyone know some good methods to back stuff up? Like I would want to backup my music I have on my PC and this doesn't change much (if at all). But I want to also backup stuff like any project files however some of these will chnage and other won't, is there any way to avoid me backing up files that haven't changed without manually checking each one?

I guess all I want to back up is my Music and my project files, suppose project files should include all kinds of things I'm working on including website stuff. As a guide on the sizes we are talking here I have approx 25GB worth of music (anybody who is wondering no I didn't download it) and my project folder is currently 0.5GB but I haven't took loads of the files off my spare PC yet so that will probably be looking at about 1.5GB after I get round to that.

Thanx
