DPm 2012 R2 leaving .avhd files behind. RRS feed

  • Question

  • Hello All,

    We are using DPM 2012 R2 to backup the VMs on a Server 2012 R2 Hyper-V failover cluster. I was browsing through the CSV looking at the various VHDs when I noticed that many of the VMs have anywhere from one to as high as 10 avhd and avhdx files, with varying dates / timestamps, stored in the folder containing the VHD file associated with a given VM.

    When I manage the VMs via the Hyper-V Manager, I see no checkpoints associated with the various checkpoint files.  It's almost as if DPM finished backing up the VM and failed to remove the avhd(x) files.  When looking at the settings for the VM, I see the original VHD as being the current hard disk file and not any of the other avhd(x) files.

    Would this indicate that I can just delete the stray avhd(x) files using the file manager?  If the backup process completed enough for the original VM VHD to be named in "settings", shouldn't that indicate that the avhd(x) files were properly merged but not removed from the file system?

    Thanks in advance for any assistance.

  • Can you try to shutdown one of the VM's and check if snapshot files are being merged and removed?

  • You may want to shutdown the primary VM and see if it go away. If not, copy those to other place and try these options listed here:- https://blogs.msdn.microsoft.com/charles_sterling/2008/08/06/what-are-all-these-avhd-files-and-how-to-magically-make-them-go-away-hyper-v/
