The error message you are receiving indicates that the Mars agent is encountering an issue while backing up the Windows system state, and the Windows Server Backup has failed with the message "None of the items included in backup were backed up."
- HResult: 80780049: This is a generic error code indicating that the backup operation failed. It typically occurs when Windows Server Backup encounters an issue during the backup process.
- DetailedHResult: 8078010E: This specific detailed error code often points to a failure related to the Volume Shadow Copy Service (VSS), which Windows Server Backup relies on to create a snapshot of the system state for backup purposes.
To troubleshoot and resolve the Issue, please follow the steps below:
- Check VSS Writers Status:
- Run the command
vssadmin list writersin an elevated Command Prompt on the server where the backup is failing. - Check the status of all VSS writers. Look for any writers that are in a failed state (
State: [8] Failed) or other non-stable states. - If any writers are in a failed state, this indicates an issue with the VSS service or with specific applications that use VSS.
- Run the command
- Restart Volume Shadow Copy Service (VSS):
- Sometimes, restarting the VSS service can resolve transient issues with VSS writers.
- Open Services (
services.msc), locate the "Volume Shadow Copy" service, right-click on it, and select "Restart".
- Verify that the Windows Server Backup service is running on the server. You can check the status of the service in the Services console.
- Check if there are any pending Windows updates that need to be installed on the server. Also ensure the MARS agent is updated - download it from here and then try backing up the system state again.
- If you are still facing issues, you can try running the Windows Server Backup tool manually to see if it generates any error messages. You can run the tool by opening a command prompt as an administrator and running the command "wbadmin start systemstatebackup -backupTarget:<backup destination>".
