Cause

Solution

1.  Check that snapshot providers are installed on the system being backed up.
  • Open a command prompt.
  • Type "vssadmin list providers"
  • If nothing is returned, then there is most likely an issue with VSS that will most likely need assistance from Microsoft to resolve
    • You can also verify that VSS is properly registered by checking the following registry key:
      •  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\Providers\{b5946137-7b9f-4925-af80-51abd60b20d5}
  • If writers not listed or show they are in an error state, reboot the server and run the command again
 


2.  Change the backup job to use a specific snapshot provider.
  •  Open the backup job properties.
  •  Navigate to Advance Open File.
  •  Confirm the "Use advanced open file option" is checked.
  •  Select the appropriate snapshot provider - "Microsoft Volume Shadow Copy Service" with "System" selected in the pull down menu is typically best:
