I have tried uninstalling & reinstalling the MARS Agent, but this has not helped.

Answer 1

TBS that resolved the issue:

Deleted Azure Backup add-in in the dashboard, which deleted MARS, as well, reinstalled MARS Agent and re-registered the server to the vault and the OnlineBackupProvider.exe was gone.

• Manually ran the scheduled task on the Task Scheduler using PS, but it failed due to insufficient privileges. The powershell execution policy was set to AllSigned, preventing the schedule task run; switching to RemoteSigned resolved the issue.
• Backups jobs ran fine, the scheduled backup tests worked.

Answer 2

@Mark Davies Sorry for the painful experience.

The Windows Azure Backup Agent logs the status of backups and their success or failure to a separate event log in Applications and Services LogsCloudBackupOperational. I believe that an unexpected or corrupt event log entry is preventing the integration service from reading this event log properly.

1. Stop Windows Azure Backup Integration Module Service,
2. Clear event log under Applications and Services Logs\CloudBackup\Operational,
3. Start Windows Azure Backup Integration Module Service.

This should help resolve this issue.

Apparently I need to pay for a support plan before I can open a technical support request.
