Symptoms
Quiesced snapshot creating failed during backup running, the below error message can be found from the Windows event log viewer.

During some rare situations, the unregister action is not applied. The quiesced snapshot creation will then start to fail.
During some rare situations, the unregister action is not applied. The quiesced snapshot creation will then start to fail.
Resolution
Open the Registry Editor using command "regedit" and enter the below path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VSS\Providers
Most of the time we see only two items under "Providers". Both of them are released by Microsoft as embedded. If see "{564d7761-7265-2056-5353-2050726f7669}" exits like in the figure below, the VMware snapshot provider was not unregistered from last time of backup action.
We must delete it manually because the VMware snapshot provider must be registered once again during quiesced snapshot creating next time.
Make a backup on the current register location then just have ""{564d7761-7265-2056-5353-2050726f7669}"" deleted as well. Then the quiesced snapshot can be created successfully.
