If you managed to be able to get RsyncX working for backup of your OS X desktops to an OS X Server using my other script on this site, you are probably wondering how to recover a system from such a backup. I've worked out a way to do that from a network boot. Assuming you have already put into place a NetBoot server that will allow you to boot your Macs from a server to an OS X desktop (a good tutorial is found on bombich.com), all you need to go is get RsyncX onto that image and put the script below on the image as well. Then, when you need to do a full system restore to a new disk, you'll boot from the NetBoot server, use Disk Utility to partition and format the drives, then the script below to finish the job. When you partition and format the drives, be sure to use exactly the same names for the drives that you used before. This is how the script will know what files to put on what drives! If it can't find a matching name, it won't restore the disk. The script below will connect to your RsyncX server (provided you modify it with the ID and password information you used to do the backup server), pull down the backup data for a given machine and drive based on parameters you specify, and place it on the appropriate drive. If the drive is bootable, it will issue the relevant commands to make the disk bootable (or at least it will try to).
