Description

This error is usually caused by an issue with one of the volumes within the backup set. More information about what caused the error can be found at the bottom of the backup report.

Resolution

The error's known causes and resolutions are described below.

Known Cause 1 - The VSS writer experienced a partial failure.

This can occur when there is an issue with one of the components within VSS. To troubleshoot the error, you will need to learn more about what caused it by checking the component level error state and by checking the Event Viewer.

Check the component level error state

Check the component level error state by running the following command from a command-line interface: vssadmin list writers

This will list the VSS writers present on your system. Look for any VSS writers that are displayed with errors as this will indicate what part of the snapshot caused the error.

Check the Event Viewer

Open Event Viewer by clicking on Start > Run > Eventvwr and check if there were any specific VSS or SPP warnings or errors generated by the system during the backup process.

The specific logs to check:

  • Backup logs: Applications and Services Logs > Microsoft > Windows > Backup
  • If running Hyper-V then check Applications and Services Logs > Microsoft > Windows > Hyper-V-VMMS.

These event logs should provide a detailed description of what may have caused the error.

Known Cause 2 - Sharepoint not updated correctly on SBS 2011

There is a known issue where Sharepoint needs to be updated correctly to avoid this error occurring. Further information on this can be located at https://www.backupassist.com/blog/support/microsoft-important-update-for-sbs-2011-and-sharepoint-2010-issue/.
