Hmm, won't most tools create an ISO filesystem image from a CD? I would expect 
that's good enough in nearly all cases, although possibly not for things like 
games consoles where I believe the original media's screwed around with as an 
anti-piracy measure.

Personally I find that I only ever use a few percent of the commercial 
software on a CD, though - e.g. I'll just install the app but not all the 
bundled junk that comes with it. Saving an archive image means you get 
everything, warts and all. For a true archive you should save everything, but 
if it's really just for personal use I'd be tempted to just save what you 
think you'll need.
