Maintenance structure backups may not start if there is one already in Waiting state.
Backup will not start (either scheduled or manual). Current state is WAITING.Symptoms:
Cause: The two executables associated with the maintenance backup can sometimes get stuck in a Waiting state (even if the previous backup has completed), preventing new backups from starting. Resolution: Terminate the processes AfwBackupService.exe and AfwBackup.exe on the backup node and try to start the backup again.
