DPM 2012 R2 - Azure Cloud Backup Error (3188/32505) RRS feed

  • Question

  • Good day to all.

    Last month we set up monthly backup of some folders from file server (physical server, OS Windows 2012 Standard) through System Center DPM 2012 R2 (physical server, OS Windows 2012 Standard) to Azure Cloud Backup. Size of protected data: approx 1,6-1,8 Tb.

    First backup (1 september) was successful.

    Second backup (1 october) failing - job starting, running for ~3 minutes and completes with critical error:

    Creation of online recovery points for E:\ on FILE-01.domain.local have failed. The last online recovery point creation failed for the following reason: (ID: 3188)
    An unexpected error occurred during the operation. (ID: 32505)

    Read KB article

    Error 3188 can occur if DPMWriter service isn't running - but this service running OK (all local backups work just fine)

    Error 32505 not listed in KB article (!)

    Updated DPM from UR6 to UR7, and Azure Agent to last version (2.0.8719.0) - problem not resolved.

    Checked recovery from first onlne recovery point - successful (so, Azure Vault is accessible).

    Dunno what to do next.

    Thanks, but it's not helped - i already updated DPM to UR7 (correct one, re-released) and Azure Agent to 2.0.8719.0.

    Russian community dropped me few links on similar problems - "DPM 2012R2 Online Backup Error -- ID 3188 and 34504" is almost just like mine. Unfortunatly - no answer from august.

  • Hello.

    Thanks, i read this article.

    I have DPM server and file server on Windows 2012, so 1700Gb limit is not applied.

    Disk, where Azure Cache is located, have approx 1Tb available (>50% of protected data size, while recommended 10-20%). Also in CbengineCurr.log there is no error "Failed: Hr: = [0x8004240f] Error in extending the volume"

    Just this multiple errors in CbengineCurr.log:

    WcfClient.cs(986) 3244F62E-FDAE-482B-AD06-7955E24DD2C3  FATAL Failed to make web service call | Params: {Exception:  = System.ServiceModel.FaultException`1[Microsoft.Internal.CloudBackup.Common.FailureModeling.CloudServiceFault]: Internal Service Error (Fault Detail is equal to ErrorCode = CloudInvalidInputError, DetailedErrorCode = 0, DetailedErrorSource = None/Client, Message =

  • Deleting contents of folder \AzureCache\Scratch\VHDs solved problem.

  • Hi, deleting the contents of the folder \AzureCache\Scratch\VHDs may have solved the problem but with the latest MARS agent releases, the product team says this can result in a problematic situation. Therefore, Microsoft does NOT recommend continued use of this solution.
