BE 2014 Hyper-V Differential backups of VMs with GRT enabled receive exceptions - no data backed up

Created: 28 Jul 2014 | 7 comments

I've just installed and configured Backup Exec 2014 on a Windows 2012 R2 Hyper-V server and I'm receiving the following exception when I attempt to run a differential backup of my VMs with GRT enabled:


During Granular Recovery Technology (GRT) operations, the necessary boot configuration files could not be loaded. Backups that were enabled for GRT may not be available for restore.


No data is available for restore for these differential backups.  Full backups succeed without issue.  This exact error happens on both environments that I've installed BE 2014.  Guest VMs are all Gen 2 VMs and both have 2012 and 2012 R2 guest VMs.

Thanks!  I reviewed the KB and I don't see that it applies.  VMs are supported OSs (2012 and 2012 R2) with no reported disk issues - VMs are online and running at the time of backup.


I'd normally call in for support, but we're in a trial mode with these before having our clients buy the product, so I have no support options.

I am seeing this happen on fulls, but not after installing the agent on the VM. Same situation Win 2012R2 VM running on a Hyper-V 2012 R2 cluster.

are you getting an error with a VM which is a Domian controller as there is a known issue going on,

I don't know about tundrageek, but my VM was a normal member server.

I'm seeing the same error on both domain controllers and member server VMs.

I would request you to open a support case for us to review the logs and see what exactly is happening
