Backup Hyper-VM including Checkpoints RRS feed

  • Question

  • Hi..

    we are running DPM 2016 RU6 to protect our clustered Hyper-V (2016) VMs.

    Now I've tried to restore some of them and I'm wondering why the recovered VM lost all her Checkpoints...

    Only one vhdx file was restored. I've tried also a network folder target. One vhdx and two config files (vmcx, vmrs) are the only one that were restored.

    Does somebody know if this is the default behavior, that only the current selected/running checkpoint will be used for the backup?

    Is it possible to enable DPM to backup any VM Source?

    Use a file system backup to backup the VM folder are no option for us because the VMs are running on a S2D Cluster and so the storage location of the VM can dynamically changed...

  • Hi Alexander,

    In general it is recommended to avoid having checkpoints during backup times, as it can cause problems.

    Generally, DPM requests Hyper-V to create a checkpoint for the virtual machine as part of the VM backup process. After DPM completes the backup, it sends a backup complete notice, and then Hyper-V merges the checkpoint back into the primary .vhd/.vhdx file and deletes the .avhd/.avhdx file.

    I believe it is by design that DPM backs up the current running checkpoint that is being used, I don't think this can be changed.

    Best regards,
