Off-host backup error
I try to perform off-host backup Hyper-V cluster and got error.
System spec.:4 nodes Windows 2012 R2 Hyper-V, HP MSA 2040 iSCSI SAN.
Installed latest 3.1.0.40 HP MSA2040 VSS and VDS to BE server and Hyper-V nodes.
ADBO installed.
After job started volume snapshot at MSA2040 is creating, spliting and mounting to HV node and BE. After occurred error:
The network connection failed during the snapshot. Check the network, and then run the job again.
V-79-57344-34109 - ADBO: One or more of the volume snapshots could not be transported to the Backup Exec server. The selection that failed was VRTSRV::\\MSK-Hyper-V.msk.uac-gp.ru\Hyper-V?HA?VM\msk-vm-sp-test. Manual resynchronization of the volumes might be required.
V-79-57344-34108 - An unexpected error occurred when cleaning up snapshot volumes. Confirm that all snapped volumes are correctly resynchronized with the original volumes.

I am not sure Off-host supports Hyper-V Agent backups - it definitely did not with older versions of Backup Exec and I do not believe this status has changed.
EDIT: If you check the admin guide for information against Off-Host it only discusses VSS operations against NTFS (in other words standard files and folders), SQL and Exchange. Hyper-V is not mentioned (Note VMware does not need offhost as it has SAN Transport so would not need a mention anyway)
This does indicate that a Hyper-V agent backup (where the VHD files of the VMs are held in hardware that would usually support Off-host) would not appear to be supported.
What would be supported, for a traditional Remote agent backup with Off-host enabled, would be remote agent backups of the VMs where a volume is presented, possibly via iSCSI, into the VM that is not a VHD but instead is held on off-host supported disk storage and the volume contains file system data, SQL data or Exchange data.
