I am trying to run backups of a VM within Hyper-V through a 3rd Party BDR appliance. It works fine with all the other servers on another Hyper-V host, but this one does not seem to work.
The error events generated on the host are:
10145, Hyper-V-VMMS
The virtual machine 'XXXXXXXXXXXXXXX' cannot be backed up because either the file groups reported during OnIdentify has changed, or the supported backup type (hot backup or saved state backup) reported during OnIdentify has changed. Try not to perform any configuration changes to the virtual machine between OnIdentify and OnPrepareBackup.
--and--
Event 8229, VSS
A VSS writer has rejected an event with error 0x800423f3, The writer experienced a transient error. If the backup process is retried,
the error may not reoccur.
. Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.
Operation:
PrepareForSnapshot Event
Context:
Execution Context: Writer
Writer Class Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de}
Writer Name: Microsoft Hyper-V VSS Writer
Writer Instance ID: {b7a3a019-907e-4513-a8bf-d023ae6c79c9}
Command Line: C:\Windows\system32\vmms.exe

We have already gone through all the troubleshooting attempts provided by the BDR vendor to no avail.
Has anyone else experienced this issue before with Hyper-V and a 3rd Party BDR solution?
