answer:…and why not Time Machine? It does everything you just described. In addition to individual files, Time Machine does full restores from Time Machine in the case of full system drive failure are easy apparently with the Mac OSX system installer and the Time Machine back up drive… To answer your question, Carbon Copy Cloner is a tool that creates disk images, which when mounted, can in theory mount as a hard disk on the desktop-although you can’t work from it, you can pull individual files from the volume when it’s mounted. I’m saying all of this assuming you’re on Mac OS X-right? (you were at MacWorld Expo after all).
