Azure System State Backup Keeps Failing

Question

Hi,

On a physical Server 2022, all of a sudden a few weeks ago I noticed that the azure backup system state keeps failing with this error "azure backup agent could not find any successful system state backup from windows server backup" (0x1877C)

Steps I've tried so far:

1. Update the MARS agent
2. Check for windows updates
3. Reboot the server

But nothing has helped, the backup starts running normally and then fails at some point with the same error each time. The files backup DOES work properly, it's just the system state that's failing.

Hi Azure Help

Other than the steps you tried to resolve the issue, also check the following steps

1. Check that the Volume Shadow Copy Service (VSS) is running on the server. It's good to restart the Volume Shadow Copy service once and try again
2. Check that the VSS writers' stability by using the command "vssadmin list writers"
3. Also check, if there is 5-10% free volume space available on the scratch folder location. By default, scratch folder location is at \Program Files\Microsoft Azure Recovery Services Agent\Scratch. More details here: Scratch Folder status

Hope this helps.
