DPM 2012r2 new cluster RRS feed

  • Question

  • I am in the process of building a new cluster and will be live migrating machines over to it. Assuming i setup the new cluster in my current DPM how is it going to handle this? Will it understand the machine was moved to a new cluster and just continue on backing up or is it going to require some brand new protection of the new cluster.

    I am tight on space as is and that is where my concern is.


    It is a HyperV failover cluster with agents on the nodes.

    In addition i have 1 file server that i backup with an agent on the file server, that is in a different protection group.

  • Hi,

    DPM communicates with the DPM agents that are running on the Hyper-V hosts.

    If you are migrating the virtual machines to new Hyper-V hosts, you will first of all need to install the DPM agents on the new Hyper-V hosts.

    The current protected servers will probably go in an inconsistent mode since the Hyper-V host has changed, so you will have to Stop protection of member on the migrated virtual machines from the protection group(s) and then re-add them to the protection group(s).

    Kind regards,

  • To provide a bit more information, the new cluster is 2016 vs 2012. Turns out DPM 2012 R2 cannot protect 2016 so this question is sort of not accurate, At the very least i will have to update to DPM 2016. Not sure if i want to do an in-place or a new setup. If i do decide to update the question will still stand with DPM 2016. I do see that the clustername is attached to the hyper V VM being backuped "Servername.Clustername.FQDN" So probably these will have to be re-protected. Although i would love someone else to chime in.

  • Hi,

    Here's another post regarding the best way to migrate existing DPM 2012 to DPM 2016 on a different server, see Mikes answer for the steps required.

  • Thx for the link.

    I think i am going to take the simplest approach however. My second DPM server is setup and as i migrate VMs to the new cluster i will just backup to the new DPM box.
