Initially backups got impacted with 96 status and now backups are not running when we have noticed I see all drives are in AVR Mode

1)Restarted media server----dint work out

2)services refreshed------dint work out

3)Device manager services stopped/restarted--dint work out..

4)when ran robtest received following error message:
