Can DPM 2016 back up a Hyper-V host with ReFS and if so does this affect an Exchange VM guest which uses NTFS? RRS feed

  • Question

  • Hi

    I am using DPM 2016 and one of the servers it is going to protect is a Windows 2016 server with Hyper-V, formatted using ReFS.  Firstly I want to double check this is supported by DPM 2016 (the DPM support matrix does not explicitly say it supports protecting ReFS volumes, only that it doesn't support it on Exchange servers), and, secondly, if one of the VMs is an Exchange server with NTFS, is that supported even though the Hyper-V host uses ReFS?

    Thanks

    Chris

  • Sorry if I misunderstood, as of today DPM doesn't support data types that are on non-NTFS volumes (except for the Hyper-V workloads).

    As for your Exchange, as long as it resides on NTFS volumes it should be fine, the VM itself will be backed up whether it's NTFS / ReFS.

  • Hello Chris!

    I understand the support matrix can be confusing at times, DPM 2016 does support backing up Hyper-V VMs deployed on ReFS-based SOFS clusters.

    Best regards,

  • Thanks Leon,

    I was really after whether or not we can backup the Hyper-V host itself as well even though it uses ReFS?  The other question is regarding the Exchange 2016 server, which although it will be using NTFS within the VM, the VM itself will be situated on an ReFS volume on the Hyper-V server (standalone) - will this cause me any problems?

    Regards

  • Thanks Leon,

    If the Hyper-V server has an NTFS C drive and the volume for the VMs is ReFS, I assume I will still be able to protect the C drive and possibly system state(??), but not select the ReFS drive for data protection (I won't necessarily need to protect the ReFS volume anyway as I will back up the VMs as the Hyper-V workload which you say is supported, and there shouldn't be anything else on it)?

    Regards
