Tried the following:

I rebooted the server.

Ran job but it failed with the same error.

Ran vssadmin list writers - the VSS NTDS was in error.

Ran diskpart  - automount - the aotomatic mounting of the drives is enabled.

Deleted .bak files in the registry in the following reg area:  HKLM\Software\Microsoft\Windows NT\CurrentVersion\ProfileList

Rebooted the server.

Ran vssadmin list writers - NTDS VSS was stable and was not in an error state.

Re-ran job and it failed with the same error
