Job with VSS selected in backup options failing immediately with VSS_E_VOLUME_NOT_SUPPORTED.
Could not identify VSS service in the French Win OS services list. After installing a French Win VM we identified this as 'Cliché Instantané' and it was disabled.
We started the service and reran the job but this failed again with the same error.
Recreated the job from scratch with new selection set and it run without error.
