Note: This applies to servers that are domain controllers, but if you get this error on a workstation, try the fix anyway.
I have written about the value of a system state backup, but what do you do when it fails with some arcane error message?
From what I found, this error comes from a bug in Server 2003 SP1. If you are trying JUST a system state backup, try including 1 small file from each drive on the system. Usually occurs if you have taken the prudent step of placing the NTFS log files on a different drive than the database.
