Lost Storage Volumes best way to proceed. RRS feed

  • Question

  • I will simplify here but long story short is I have the C drive from a DPM install but lost all the Storage Volumes. I am wanting to provide a new disk and just pick up with the backing up. Yes i understand it will have to re-transfer the data from source at bare minimum. How to I go about doing this?

  • Hi,

    Is the C-drive from a backup? So basically you have a DPM server with no DPM storage?

    Where is the DPM database located? Was it also lost or is it intact?

    Is there any reason why you're not simply re-installing DPM? If the DPM database is intact that is.

    Best regards,

  • The SQL was stored on the C, DPM is starting and running just fine... it is only missing the "Disk Storage" where the recovery points are stored. I am just trying to save time and effort by getting this back up and running, by providing new Disks.

  • The old storage will be sohwn as critical "Volume failed or missing", you can try to remove it with the Remove-DPMDiskStorage PowerShell cmdlet.

    If DPM is up and running you should simply be able to add new storage to your DPM environment without any issues really.

  • I have done that..... At this point what i want to do is a "Move Storage" where i can select my new disk that i have provided. However i have done that and it doesnt move in fact the console crashes.... I want to do a move storage without the old data.

  • Do you mean the "Move disk storage"?

    If you don't have the old storage available where the data actually was stored, you won't be able to move anything I'm afraid.

  • Yes.

    I have also attempted with the powershell command. Set-DPMDataSourceDiskAllocation. I have used this in the past with the -MigrateDatasourceDataFromDPM however in this case i dont have the data.


    If i run with the flag it says. "You cannot migrate a replica that is not in a valid state" but that is my goal.

  • Just to clarify since i lost a local disk.... I now have to create a new protection groups creating all new recovery points and and re uploading all my data to azure. While I can keep the current azure recovery points i now have to have new azure data basically doubling the size of data i am using in azure while maintaining the old protections groups just to get the data out of azure.

  • The MigrateDatasourceDataFromDPM.ps1 works indeed but with the data.

    I assume you were running backup to disk, and then an online copy to Azure?

    Without the previous disks/data there's not much that can be done, you will basically have to start all over I'm afraid, so in your case you should remove all backup items from Azure to avoid having double sized data and start re-protecting everything.

  • I appreciate your assistance...

    This seems like something DPM should be able to handle.

  • Yes, unfortunately it can't, the backup server also needs to be backed up, etc etc... it's a never ending story.
