This error translates to the VSS error “VSS_E_WRITERERROR_NONRETRYABLE” or “The writer experienced a non-transient error. If the backup process is retried, the error is likely to reoccur.”
This error is expressing that a generic error occurred in the backup process and is likely to happen again. This error is typically due to system configuration or other software that prevents the execution of a shadow copy. In order to investigate the core issue, refer to the System and Application event logs from the guest at the time of error.
Investigation Advice
Consider the following:
- Check the System and Application event logs around the time that the job failed.
- Using the Diskshadow Utility to Manually Test VSS Operations
- How to Use VSSTrace to Collect VSS Diagnostic Logging
Customers have reported that in some situations, VSS issues were resolved by rebooting the Guest OS of the VM being backed up. For example, a pending Windows update may cause problems.
