DPM Online recovery point creation failed (error 3188)... RRS feed

  • Question

  • Hi everybody,

    I've installed DPM 2012 R2 version 4.2.1417.0 on a Windows 2012 R2 and both have all the latest and greatest patches.

    My "local" disk based backups appear to be working fine so I want to ensure that I've got offsite backups and started the process to add Online Protection.

    So, I...

    1. I created a backup vault in Azure installed the latest Azure backup agent (2.0.9028.0).
    2. I've enabled Online Protection for the Protection group and I'm trying to backup only 1 server to the Azure (for now).
    3. Waited for the Azure backups to start...

    Unfortunately, the Online recovery point creation always fails with the error 3188.

    In fact, the "Online recovery point creation" process has never worked so far (I've been trying several things from the forums over the past week, including a complete un-install and re-install of the Azure Backup agent and deletion and re-creation of the backup vault in Azure).

    Saddly, none of the solutions I tried from the forums fixed the problem.

    I see the following errors in "Event Viewer -> Applications and Services Logs -> DPM Alerts":

    • Creation of online recovery points for C:\ on have failed. The last online recovery point creation failed for the following reason: (ID: 3188). Operation failed. (ID: 120002)

    I see the following errors in "Event Viewer -> Application and Services Logs -> CloudBackup -> Operational":

    • The backup operation has completed with errors. (Event ID 11)

    I see the following errors in "Event Viewer -> Applications":

    Does anybody have any idea what might be happening?

  • Ok, so, I had to open a ticket with Microsoft and here's the root cause in my very specific case...

    Root cause (for my particular case):

    When the Azure Backup agent installed itself, it added a double backslash, i.e. "\\", in the "scratch” location path.

    So, when the Online Recovery jobs ran: they always failed miserably and generated the error 3188.

    Solution (for my particular case):

    1. Start the Registry Editor on the DPM server.
    2. Go to HKLM\SOFTWARE\Microsoft\Windows Azure Backup\Config\ location.
    3. Edit the “ScratchLocation” key data to remove the double backslashes in the path.
    4. Go to HKLM\SOFTWARE\Microsoft\Windows Azure Backup\Config\CloudBackupProvider location
    5. Modifiy the “ScratchLocation” key data to remove the double backslashes in the path (yes, that’s weird, it’s stored in 2 location).
    6. Close the Registry Editor.
    7. Reboot server.
    8. Once rebooted, log back into server, start DPM console, select an Online Recovery job that failed, right-click on it and select “Resume Azure backups”.
    9. Monitor the job by going to Monitoring -> All jobs in progress.
    10. After a couple minutes, if it works, you'll see the total data it has transfered so far to Azure.

    More Details...

    When troubleshooting this issue with Microsoft, the tech opened the "CBEngineCurr.errlog" file in "C:\Program Files\Microsoft Azure Recovery Services Agent\Temp" and looked for "Backup Progress".

    In each case, he would see a line that said "Starting" and the next one would say "Failed".

    However, upon closer inspection, a few lines above the "Starting" and "Failed" lines, there was a warning that the backup agent was not able to open the "scratch" location. The text of the warning included the path with the double backslashes... so that's how he found the root cause.

    I hope this helps someone, somewhere...

  • This was exactly my issue. Very odd that it puts that "\\" in there, mine was just before the 'Scratch' folder. Fixed in both places and all is well.

    Thanks again!
