Clonezilla is OS independent. It boots into temporary live Linux and will back up any HD with any OS. The image is not bootable and will not conflict with anything. It must be restored to be usable.
Thanks for that info. For me, that is not ideal - if I have to restore to use the image, it's pretty hard to test that image. That means wiping out my original, just to test it right? So if the image is hosed up (or more likely, I screw up something), I'm now dead in the water.
That's why I'd like to be able to create the image, and re-boot into it w/o changing anything on my system, other than pointing to it.
In Linux, the GRUB boot loader (GRand Unified Boot-loader) seems needlessly complex and inflexible (or I just don't understand/appreciate it), as it doesn't allow you to boot from that image (because the UUIDs are also cloned, so create a conflict), and updating it seems ticky and can leave you with an unbootable system until you fix it with a LIVE CD/USB. I've read about the ways to change the UUID on the clone, but I think I only got it to work once, and it was pretty involved.
I've resolved myself too just backing up the data. Fortunately, reinstalling Linux is pretty painless, and I've documented my apps/set up (but are out of date now!). And I haven't had a need to reinstall the system anyhow, so it hasn't mattered (yet!).
most of these solutions seem very complicated (to me at least). I use Carbonite for all of my computers. I set it up and then forget it. Once a week (or maybe it's once a month) I get an email that says how many files are backed up or if there are any problems: "hey, computer xyz hasn't been backed up in a week, you should check on it." It's a fixed price regardless of the amount of data.
The other solutions offered probably sound more complex than they are. But Carbonite might be a fine way to go as well. But, have you tested it? Have you routinely tried recovering a file? If not, see my previous note that says
"If you have not tested your back up, assume you do not have a back up".
Also, if you have a major crash, you have to wait for Carbonite to ship you a hard drive (overnight I assume), and you still have to go through a recovery process from that drive - and that might keep you down longer than if you had an image on your shelf.
