You could probably do something quite nice with PXE booting either. If you are familiar with the LTSP, Clonezilla and (in particular) FOG projects, they do similar things in certain respects. FOG is a network-based cloning solution. You: 1. Set all of your desktops to PXE boot. 2. Set up your DHCP server to point PXE clients at your FOG server. 3. On boot, the FOG server then gets to decide whether each client boots the local hard disk as usual, or goes into some other mode such as uploading an image of itself to the server or downloading a new image to its hard disk (either unicast or multicast). You control FOG itself using a web interface, though that's not necessarily a requirement. It seems plausible that you could have a similar PXE set up with a "bacula restore" mode. Most of the time the server just boots as normal, unless you tell the PXE boot server that this particular computer should go into Bacula restore mode. It then boots a small linux OS which includes bacula-fd and perhaps bconsole. A script could then format the partitions, trigger a full restore, set up grub and reboot onto the restored image. I'm not saying this would be a small piece of work, but a fair bit of it could probably be lifted from FOG. Generalising the detailed restore process across all of your servers might be difficult and across servers in general might be really tough. You have to deal with issues like which partitions exist, which should be formatted/wiped, setting up software RAID partitions, etc. The "generalised bare metal restore" conversation has come here before.
