A bunch of my DPM SystemState backups were failing. The volumes would backup correctly, but system state wouldn’t. I sicked one of my junior admins on this (Robert Holbert), and he figured it out.
There were two problems:
- I didn’t have Windows Server Backup installed on many of my servers. This is a pre-req for doing System State backups.
- System State backups require 10-15GB free on the windows volume to store the system state.
After installing WSB and freeing up some space, everything backed up correctly. Woo! Way to go RH!
