Modern Backup Storage - Upgrading from DPM 2012 to 2016 RRS feed

  • Question

  • Hi All,

    I have a few questions regarding upgrading DPM to 2016 and utilizing MBS to save disk space and increase backup speeds. Just a quick overview of the environment. We have a physical DPM box with a storage capacity of 42 TBs with 40 TB in use. We need to upgrade the OS to Win 2016 for MBS and then install DPM 2016.

    Correct me if i'm wrong, my understanding is that since the disks need to be formatted by DPM to ReFS the data needs to be migrated to another storage and then migrated back onto the DPM disks after the upgrade? If so, what's the best method of doing this? In addition to this, when we move the data back onto the disks the storage will still be 40 TB because the volumes are 
    fixed with NTFS as it's file system. Is there any shrinkage that happens etc?

    Regards,

    Keith

  • Yes new data on the MBS will take less storage as DPM legacy storage.

  • What you need to do is add new volume to your DPM 2016 which will be configured as Modern Backup Storage. Stop the protection of your data sources with Retain Data option. Once done, simply add the data sources to a new protection group with Modern Backup Storage.

  • Thanks Matej,

    Your answer helped me get a greater understanding of the process needed for migration. I was thinking of copying the entire volume(s)/Disk(s) rather than the actualy data within the volumes. New protection groups will need to be created and the data copied into these.
