To start troubleshooting a device that’s not able to run backups, follow these instructions:
Launch the Backup Manager client on the server by going to the browser and entering http://localhost:5000.
If there is a stuck backup job, hit Cancel.
Then, open Windows Services and stop Backup Service Controller.
Go to Task Manager and see if there are any instances running for BackupFP.exe and kill it.
Back to Windows Services, restart Backup Service Controller.
After that, go to the Backup Manager again and start a new backup job.
