Server :: Phone System Reload Backup System?

At work we have a linux based ip phone system. Now this system was buggy for a bit but we now have it working perfectly. As it is we clone this hard drive and on backup I clone it back. This works but if for whatever I'm not in the office the backup can't go through because apparently no one can read the VERY simple instructions. What i would like to do is burn a cd with a copy of the hard drive (this configuration will change once every 6-12 months at maximum) as well as a VERY minimal linux install.

The goal is they stick the cd in and reboot. The system loads the super minimal linux then it runs a batch file that clones the portion of the CD that has the hard drive onto the system then it asks the nice moron....err....person...to remove the cd and reboot All I need is a a bootable system to a bash script that will run live from cd. I can make the nice bash script that puts to the screen a nice ascii graphic telling the lucky sap it's running and to come back in a little bit to make sure it's done.
