VSS writers inside virtual machine 'CONTOSO' failed to perform BackupComplete to its shadow copy (VSS snapshot) set: Catastrophic failure (0x8000FFFF). (Virtual machine ID 9851BE14-F276-459D-8D60-DF73B67EB658)
What does it mean? Writers on virtual machine are OK and all backups are successfull. Every day I have one 10172 event for one backup in Hyper-V-VMMS event log.
