My Acronis stopped backing up due to an error

Thread needs solution

My Acronis stopped backing up due to an error. The error listed is: Failed to create volume snapshot.

As found I downloaded the app VSSDoctor and ran it but from that point on I'm lost.

Can you help?

Regards,

Robert

Hello!

The provided information indicates that there are issues with the Volume Shadow Copy Service (VSS) on your system, particularly with the WMI Writer. Here are some steps you can take to address the reported problems:

  1. Check and Restart VSS-Related Services:

    • Open the Services application (you can type "services.msc" in the Run dialog).
    • Locate and restart the following services:
      • Volume Shadow Copy
      • Microsoft Software Shadow Copy Provider
  2. Re-register VSS DLLs:

    • Open Command Prompt as Administrator.
    • Run the following commands:
      
       

      cd %windir%\system32
      net stop vss
      net stop swprv
      regsvr32 ole32.dll
      regsvr32 vss_ps.dll
      vssvc /register
      regsvr32 /i swprv.dll
      regsvr32 /i eventcls.dll
      regsvr32 es.dll
      regsvr32 stdprov.dll
      regsvr32 vssui.dll
      regsvr32 msxml.dll
      regsvr32 msxml3.dll
      regsvr32 msxml4.dll

    • Restart your computer.
  3. Check and Fix NTFS Volume Access Control Configuration:

    • Review the NTFS volume access control configuration for the E: drive, as it is flagged with warnings.
    • Ensure that the "SYSTEM" account has "Full Control" access.
  4. Investigate VSS Writer Issues:

    • Check the Event Viewer for additional information on VSS-related errors or warnings.
    • Focus on events related to the WMI Writer (Class Id: {a6ad56c2-b509-4e6c-bb19-49d8f43532f0}).
  5. Investigate Disk I/O Load Error:

    • The error occurred when checking disk I/O load. Investigate the cause of this error, as it might be related to performance issues.
  6. Review Shadow Storages Status:

    • Investigate the error in checking VSS Shadow Storages. This could be related to the WMI Writer issue.
  7. Check for Adequate Disk Space:

    • Confirm that there is sufficient free space on all volumes.
  8. Address VSS Writer Errors:

    • For the WMI Writer with Instance ID {e5b2bf64-d292-4ec5-9e1f-2450a13f3585}, check the specific events related to it in the Event Viewer for more details.

Thanks in advance!

Robert, if you haven't already done so, then reboot your computer which can clear out a lot of these types of errors!
