CAPI2 Event Error ID 513 encountered in Server 2012 R2 RRS feed

  • Question

  • Hi,

    I am trying to do a backup on my AD server (Server 2012 R2 with latest patch) using Windows Server Backup, however, I encountered error when doing a full backup.  It stated "system writer is not found in the backup".  

    In Event Viewer, error ID 513 is logged as well.  

    CAPI2 Event Properties 513

    Cryptographic Services Failed while processing the OnIdentity() call in the System Writer Object. 


    AddCoreCsiFiles: RtlConvertNtFilePathToWin32Path() failed. 

    System Error: 0xC0000039 (unresolvable)

    The backup Operation that started at ‘2019-09-24T00:55:27.911302400Z has failed with following error code ‘0x80780102’.  (The system writer is not found in the backup.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved. 

    System writer is indeed not shown when I executed "VSSadmin list writers" in command prompt.  

    I have found some solution online but I am uncomfortable with the instructions, such as, amending file permissions.  I have two ADs running and both encountered the same.  I am not able to do backup prior to changes, hence, I need to be very careful not to destroy my ADs with the steps.  From the past logs, it seems that this problem happened since day one.  

    Would anyone be able to share more with me?  Appreciate lots in advance.
