VSS writers inside virtual machine failed to perform BackupComplete to its shadow copy (VSS snapshot) set: Catastrophic failure (0x8000FFFF)

Hi jackie.butler,

From the current information, please first make sure that the hyper-v VSS writer is in health state using VSSadmin list writers command from an elevated command prompt. If the writer is in failed state, please restart Hyper-v Virtual Machine Management service.

Some folks fix it after moved the vm data to sub folders in the CSV, please try it then monitor the issue again.
