"Backing off to CD is easy. Your Downloads folder :) After backup if you want to keep the stuff on your harddrive, move them over to an Archives folder with the same structure. And start over." That's exactly how I handle that. I have a special folder structure for my downloads and I move the zip-files from there - after backup - to an archive folder with the same struc to have the files still on my HD. Interesting to hear, that s.o. does the same. :)
