This cannot be a DB backup - you are backing up a directory using Standard policy type.

We see 2 errors here - Status 84 and 20.

Before the errors can be fixed, we firstly need to find out what is causing it.
Seeing job details may help to point us in the right direction.

I uncheck the BMR on the policy  , the error code 20 not to occur again. 

Thank you Marianne
