Backup Exec 2014 Hyper-V errors/questions

Hi,

 

Different error below, but give it a read as it relates to dynamic disks:

Also refer to the TNs below which relate to your error:

Thanks!

GRT of dynamic disks are not supported. See page 31 of the SCL below http://www.symantec.com/docs/TECH217478. Turn off GRT for your backups or backup your VM's as if they are physical machines

Without GRT I cannot restore individual files, I have to restore the entire machine correct?  

 

Do you know if switching from dynamic to fixed disks will solve the issue?

Yes.  This is correct.  Alternatively, you can back it up as if it is a physical machine, but recovery will be more difficult.

Note that dynamic disks in the SCL refers to dynamic disks in the VM sense and not dynamic disks of the OS kind.  If you change to basic disks in the VM sense, then you can do GRT.

Ok, I am confused.  I came across this thread which you also commented on:

So Backup Exec does support hyper-v guests on dynamically expanding disks so long as the guest machine does not contain dynamically expanding disks within?

- Edit - 

I think I see now that this does not apply to the vhd type (fixed vs dynamically resizing) but rather the disk type (dynamic vs basic) within the VM.

 

I think CraigV and PKH mean the dynamic disk inside the VM and not the VHDX/VHD.

 

I have exactly the issue and I have logged a call to Symantec.

The case is passed to Backup Exec advance team and they have collected SGMON log.

 

I am waiting for their reply now.

Yes, that appears to be the case.  I don't know why my backups were failing with that error messages, they VHDX files were dynamic but the disk was basic inside the VM.  I am trying to replicate the errors again now.

 

 

I have a exactly issue. luckily, it just happens in differential backup intermittently.

 

Symantec advance team support will collect the debug log again today.

I had a few good days but one backup failed last night.  It was during the duplicate to disk stage.  

Final error: 0xe0009741 - Failed to mount one or more virtual disk images. Restores that use Granular Recovery Technology may not be available from this backup set.
Final error category: Resource Errors

I never encounter an error when duplicate to disk.

My backup job is backup to disk and then duplicate to tape. The error would happen when duplicate to tape in differential job. Symantec Advance team is still investigating the issue now.

is your job similar to mine?
