FYI to anyone who's curious -
I have successfully done a fill system state restore on a 2008 server using BE v11d. The process is the same as 2000/2003 :
-Verify you've got a good backup, and the tapes on hand
-Reinstall the server with only the OS, no applications
-Install the BE agent. (No reboot needed)
-Find the most recent good, full backup of your server
-Run a restore job, selecting all files, all system state, and all Shadow Copy Components for that particular backup
-Let it run. Restore time will be about the same time that it took to backup - check your Job History log.
-When the restore is done, you will get an alert telling you to reboot the server. Do that.
-The server will take a little longer to boot up than usual - this is normal.
-Login & verify everything is working.
