hye,
i have encounter a backup issue for Windows Server 2012 R2
when i backup a hyper-v using Unitrends.
as i check the 'vssadmin list writers'
i can see one error
Writer name: 'Microsoft Hyper-V VSS Writer'
Writer Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}
Writer Instance Id: {4758c3a4-e8e4-4814-81d8-9d4cbf93cb26}
State: [8] Failed
Last error: Non-retryable error
after i restart the VMMS service, the state will change to stable and for last error,
it will state no error. But this error will re-appear again after I execute another hyper-v backup again.
this is the warning log for VSS
