In addition to the recommendations of others...

1. You didn't give us the context of the "not working": if the backups involve
   client schedules, make sure that you restart those processes, to pick up
   the new client specs.
2. Always do 'dsmc query inclexcl' after making such a change, to assure that
   all specs are present as desired (and that the client is happy with them).
