How to check VSS (Volume Shadow Copy) is working outside of quiescing and backup.
1. Open a CMD prompt
2. Type ‘DiskShadow’ and hit Enter
3. Enter the following commands:
SET CONTEXT PERSISTENT NOWRITERS
SET METADATA example.cab
SET VERBOSE ON
BEGIN BACKUP
ADD VOLUME C: ALIAS systemVolumeShadow
CREATE
EXPOSE %systemVolumeShadow% p: (this will map the shadow to drive P:)
END BACKUP
4. Enter the following command: LIST SHADOWS ALL (you should see the shadow information)
5. Check the Services to make sure that Volume Shadow Copy service is in a running status
6. You can browse the P: drive to see the information in the shadow
7. delete the shadow by entering the command: DELETE SHADOWS
Any errors that occur when running the CREATE command in step 3 indicates a problem with either VSS or its installed writers. Please contact the Application VSS Writer vendor for support.
