Backup Hyper-VM including Checkpoints

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...

Thanks

Alex
