I'm with Jonathan here. Keep with the main stream formats. 2 USB hard drives (unless you're getting into terabyte ranges) are probably the best bet - with one kept off site. I've had CDs go unreadable after a couple of years.
Regardless of the format (and this is why I prefer HDs) one element of the backup process that I think most folks ignore is to attempt a recover periodically. You need to make sure that both versions are truly recoverable every now and then, but probably no less than annually. If you've got a couple of hundred cd's that's a pita and with today's mega files, dvd's are still a hassel.

thanks guys,
I got external drives and all that, but what about software that backs up your stuff as you add to your disk, perhaps I am getting a bit anal here, thinking of an almost real time backup, but not quite.
I remember reading somewhere that a software would keep track of new created files and would add them to the backup as they were created, now I may not need this.
I am getting more and more clients work on my systems and though all their work is on raid 1's or raid 10 then it is still a concern. I have had a couple of powerfailures lately and needless to say is getting abit concerned. am I over doing it?
I guess I would like something that would actually back up for me ;-) like an extra insurance, (insurance, the one, that expires just before you need it! ohh, no that is warranty )
anyone heard of Retrospect ? backup software?
thanks for the input so far guys, much appreciated
