I'm looking to update from Ubuntu 11.10 to 12.10 in a few days but I want to be able to go back to 11.10 in case of the new version kills my install or not working with my games or you know sucking.
Now I have enough room on my 2nd hard drive to do a full backup uncompressed. I was thinking about just copying the partition but I don't want to fuss with fixing it afterwards.
So is there a simple program that can backup the whole hard drive and restore it without needing to log in? (in case 12.10 doesn't even turn over.)
