I've set up a scheduled backup using the Windows Server Backup. Also, I've created a managed service account that should execute the backup, but the Schedule wizard doesn't accept the user account.
The account is granted membership to the Backup Operators group and have all necessary permissions to the backup location.
Is it possible to assign the managed service account to the backup service by other means?
Update: since the backup is scheduled using the Task Scheduler in Windows, I've also tried to configure the job to run as a managed service account without success.
