Comment PXE boot??? (Score 1) 253
Why not just PXE boot a small OS image which does the backup and wipes the drives?? Linux or DOS will do the trick just fine. If you're trying to backup anything NT based (NT-Win7) get a read-only NTFS driver on the PXE image too. It's pretty simple really and doesn't take any real time IF all of your systems are semi-modern.
