Hello all,
I am trying to use Windows Server Backup to run scheduled backups of my Hyper-V VMs. I am using the following configuration:
- Hyper-V Server 2012
- Backup volume attached via iSCSI from SNAPSERVER NAS
- Entire volume dedicated for use of full server backup.
I access the Backup GUI via a remote mmc connection. The GUI summary page suggests that the backups appear to have been running over the christmas period:
However, Hyper-V manager reports that the guest VMs are "Status: Backing Up" and I am unable to perform any operations on them (e.g. revert snapshot).
If I click on the detail menu (i.e. local backup in above image), the MMC will hang with a marquee box saying "Please Wait". I have left this run for over an hour without it changing. I am then forced to kill the MMC in task manager.
Running wbadmin from a remote PS session, I can see that the backup job is stuck at 76% on the first VM. Using the stop job command, seems successful (i.e get status shows job has stopped before completion) but the machines still show as "backing up" in Hyper-V manager, and the command prompt does not return to the 'prompt'
The only resolution I have found to this is to restart the physical hyper-v host. As this is a production server, this is something that I REALLY want to avoid.
The error logs on the hyper-v server are filled with vhdmp error 129 "Reset to device .. was issued". This error is created every 30 seconds.
I think I am slowly coming to the realisation that I have to pay out for thrid party software :-(. Any help would be appreciated..
Additional Info:
I had a similar issue trying to run the same process, only within a 2012 Guest VM.
