I use systemimager for complete image backups of machines. You can upgrade a system completelly remotely. Has deb files. And configure it so the network address is set for each machine. I use it for 140 linux desktops. I also use it for my servers, my primary webserver went down...so I grabbed a new machine off the storage bin, plopped in the cd and voila I had a complete copy up and running in 15 minutes.
