I saw a post about disk images in another thread here about, of all things, Squeeze becoming stable and the flood of packages that might ensue. Back on Windows I knew of the ability to create images a la Acronis True Image and Norton Ghost, etc, (that's not saying I actually used them!) but try as I might I can't seem to find a solution that works for me here.
I believe I tried Clonezilla once, but it always errored out and just hung. Next to that, if that is even the correct way, I'm not aware of any way to do this simply either free or commercial. I've heard one can use the 'dd' command but that doesn't seem very intuitive to me. I'm not afraid of the command line, but not yet a junkie.
I would appreciate whatever tips you have to give on this issue since I have a tendency to experiment with, and therefore break, my main system.
