DPM 1807: How to backup ESXi VM with multiple hard drives RRS feed

  • Question

  • I'm protecting an ESXi VM that has two drives. Notice one store is using about 42GB and the other store is using about 500GB.

    I appears DPM is only protecting the primary drive with the ~42GB VM drive.  I know this because when I look in DPM I can see how much storage is being used.

    Is there a way I can get DPM to also backup the second drive?

    Thanks.

  • So it's fixed.  I'm not sure if I did anything or not, but it's protecting both drives.

    The only thing I did was turn the old ThinWare vBackup server and ran a backup job.  I didn't want the server to go unprotected so I turned on my old backup solution.  Once it finished the Thinware backup, DPM did a consistancy check and started backing up the other drive.

    May have been coincidence too and just need to wait long enough. 


    Thanks Leon.

  • Hello!

    What version of VMware ESXi are you using?

    Can you check by modifying the protection group that both drives are checked for the virtual machine?

    Best regards,
    Leon

  • Thanks for the reply.  I'm using ESXi 6.0.  This is what I see if I modify the ESXi Protection group.

  • What type of disks is the problematic VM using? Are you using any RDM passthrough disk?

    Are both disks on the same datastore or different datastores?

  • Hi.  Yes, you can see there are a few VM on this host.  All of the VMs are using an iSCSI SAN. 

    The VM that I'm having issues with is a little different.  I installed this one using an OVA.  When I installed it somehow it installed the OS on the "Local Storage" and the data drive on the LUN I setup for this VM.  I didn't think anything about it at the time as I was completely unfamiliar with this server.

    From your response it sounds like DPM detects this when setting up the Protection group?  If so, is there any way I can add a drive manually or does it require DPM detecting it?

  • If the solution is too involved, I may choose to just rebuild the VM.  The new version of the software has different system requirements compared to when I first installed it four years ago.  So at some point I'll need to reinstall the server on a 1TB LUN if I want to upgrade.

    But it would be nice to protect this server in the meantime as I have to wait until summer to rebuild the VM.

  • It does seem that DPM isn't able to identify the VM's volume on the "local storage", I'm not a VMware expert but I do have experience with it, could it be that the local storage acts as RDM?

    Because DPM doesn't support RDM and that would explain why it isn't seeing the volume.
