Hi,
Thanks for posting on the forum, it seems the issue is DPM related, however, the backup forum is more related to Windows Server backup tool and vss services, and after research, it seems the dedicated DPM forum has been closed. In order to get better help about DPM, it's recommnended to contact MS to check if you can open a case for DPM support. Thanks for your understanding!
Below is the link of the phone to contact MS support:

Thanks for your time!
Best Regards,
Anne
