My parents have a PC and a Mac, and they really need to back them up as they contain business files and that's quite important 
What would be the easiest way to achieve this? Bare in mind that it needs to be really simple, the Mac is a Mac Mini. Both machines have CDRWs, NOT DVD RW's. Both machines have 40gb HDDs.
Any ideas would be greatly appreciated
Thanks
