MSSQL Backup Failure: SQL Writer Failed

MSSQL Backup Failure: SQL Writer Failed

KB ID: 113
Problem:
When attempting to perform an MSSQL backup, users may encounter a failure with the error message "SQL Writer Failed."
Cause:
The "SQL Writer Failed" error can occur to various reasons, including:
1. VSS (Volume Shadow Copy Service) Issues: Problems with the VSS service can interfere with the backup process.
2. VSS Writer State: If the SQL Server VSS writer is in a failed or unstable state, it can lead to backup failures.
3. Insufficient Permissions: The user account running the backup might not have sufficient permissions to perform the backup.
Solution:
To resolve the "SQL Writer Failed" issue, follow these steps:
1. Check VSS Service Status: Verify that the Volume Shadow Copy service is running and functioning correctly. Restart the service if needed.
2. Verify SQL Server VSS Writer: Ensure that the SQL Server VSS writer is in a stable state. You can use the "vssadmin list writers" command to check the status of all VSS writers.
3. Grant Sufficient Permissions: Ensure that the user account running the backup has the necessary permissions to access and back up the MSSQL database.
4. SQL Server Restart: In some cases, restarting the SQL Server service can resolve temporary issues causing the backup failure.
5. Check Backup Destination: Ensure that the destination where the backup is being saved has sufficient free space.
6. Check Disk Errors: Verify the health of the disk where the SQL Server data and backup files are stored for any errors.
7. Update SQL Server: Keep your SQL Server installation up-to-date with the latest patches and updates.
If the issue persists after following these steps, consider seeking further assistance from BDRSuite support or your database administrator to diagnose and resolve the specific cause of the backup failure.
