veeam backup vs hyperv suddenly fails (Microsoft Hyperv-V VSS Writer is non-retryable error state)

Hi

2012 r2 hyperv, using veeam backup and replication 9.5 for backups.

Suddenly backup stopped working an the error that throws:

1/15/2017 3:19:47 AM :: Unable to allocate processing resources. Error: Writer ‘Microsoft Hyper-V VSS Writer’ is failed at ‘VSS_WS_FAILED_AT_PREPARE_SNAPSHOT’.
The writer experienced a non-transient error.  If the backup process is retried,
the error is likely to reoccur.
-tr:Failed to verify writers state.
-tr:Failed to perform pre-backup tasks.

If we run vssadmin list writers on hyperv host we see that Microsoft Hyperv-V VSS Writer is non-retryable error state. If we restart hyperv management service then this error disappears for awhile, until we dont trigger backup again.

we have even rebooted hyperv host but that did not solve it .

Please advise

Virtual machine on hyperv 2012r2 backup problem

Hi there.

We have Hyper-V on 2012 r2 HOST.

Virtual machine is also on 2012 r2 OS with Exchange EDGE 2013 role.
When we wish to make backup with VEEAM BACKUP AND REPLICATION (version 8 + update 3) we recieve an error.

3/19/2016 12:08:13 PM :: Unable to create snapshot (Microsoft Software Shadow Copy provider 1.0) (mode: Hyper-V child partition snapshot). Details: Writer ‘Microsoft Hyper-V VSS Writer’ is failed at ‘VSS_WS_FAILED_AT_PREPARE_SNAPSHOT’.
The writer experienced a transient error.  If the backup process is retried,
the error may not reoccur.
-tr:Failed to verify writers state.
-tr:Failed to perform pre-backup tasks.

3/19/2016 12:08:34 PM :: Make sure VM does not have ‘iSCSI Software Target Storage Provider’ feature installed.

3/19/2016 12:08:34 PM :: Retrying snapshot creation attempt (Writer ‘Microsoft Hyper-V VSS Writer’ is failed at ‘VSS_WS_FAILED_AT_PREPARE_SNAPSHOT’.
The writer experienced a transient error.  If the backup process is retried,
the error may not reoccur.
-tr:Failed to verify writers state.
-tr:Failed to perform pre-backup tasks.)

Any hints how to solve this guys?

With best regards
