I need to restore an image of my operating system to my MacBook Pro. It's about five days old. If I restore it, what happens to the files in Dropbox that are more recent than the files in the 5 day old clone? Will they be deleted when I restore? I hope not! I run both time machine and Superduper on a partitioned 2TB external drive. This is dangerous correct? If the drive fails, I lose both copies. I should actually have two external drives, one for each the superduper clone and the time machine, right?
