Phoenix agent is unable to create VSS snapshot
Resolution: If you are using Microsoft native VSS, ensure that the VSS service is running. You can access Windows Task Manager and verify that the status of Volume Shadow Copy (VSS) service is running.
If you are using third-party VSS provider, ensure that you have configured Phoenix agents to recognize the third-party VSS provider. For more information, see Configure Phoenix agent to recognize a VSS provider.
