  • Hello,

    From DPM 2016 and onward, DPM uses "volumes", in earlier versions of DPM it uses "disks".

    DPM 2016 & 2019 accepts both volumes or disks for storage, once you add a volume, DPM formats the volume to ReFS (with 4K allocation unit size) to use the new features of Modern Backup Storage.

    Note: Volumes cannot reside on a dynamic disk, use only a basic disk.

    If you have upgraded from an earlier version of DPM to version 2016/2019, and you have kept the old storage, DPM will see the old storage as "disks" and they will not benefit from the Modern Backup Storage feature, meaning they will be NTFS formatted disks.

    Best regards,
    Leon

  • Which operating system are you running your DPM 2016 on?

    The freezing problems isn't normal, since this appears to be a new installation, have you ensured that you meet all the system requirements?

    https://docs.microsoft.com/en-us/system-center/dpm/prepare-environment-for-dpm?view=sc-dpm-2016

    I would also highly recommend installing the latest Update Rollup for DPM 2016, you'll find the latest one over here:

    Update Rollup 8 for System Center 2016 Data Protection Manager

  • If the whole setup meets the system requirements and your hardware is also certified for your Windows Server version (check here: https://www.windowsservercatalog.com/), and this affects both your DPM 2016 and DPM 2019 environments, then I would suggest you create a support ticket directly to Microsoft:

  • Hi Falcon,

    What Leon mentioned is correct, however I added more information to make it more accurate for any new comers to this thread.

    <snip>

    From DPM 2016 and onward and running on Windows 2016 or higher, DPM uses "volumes" for Modern backup Storage, in earlier versions of DPM it uses "disks". 

    DPM 2016 & 2019 accepts both volumes or [disks for storage if running on Windows 2012 R2], once you add a volume, DPM formats the volume to ReFS (with 4K allocation unit size) to use the new features of Modern Backup Storage.

    Note: Volumes cannot reside on a dynamic disk, use only a basic disk.

    If you have upgraded from an earlier version of DPM to version 2016 and running on Windows 2012 R2 DPM will continue to use the old storage as "disks" and they will not benefit from the Modern Backup Storage feature, meaning they will be NTFS formatted disks.  Once you upgrade the operating system to Windows 2016, then any new protection (including stop protection and re-protect) will require modern backup storage volume(s).
