A client's TSM server has the following copygroup settings:

tsm: SERVER1>q copygroup * active f=d

                 Policy Domain Name: OPEN_SYSTEM_ENVIRONMENT
                    Policy Set Name: ACTIVE
                    Mgmt Class Name: BACKUP_SHARK
                    Copy Group Name: STANDARD
                    Copy Group Type: Backup
               Versions Data Exists: 3
              Versions Data Deleted: 3
              Retain Extra Versions: No Limit
                Retain Only Version: 91
<snip>

Because "Versions Data Deleted" is more than 1, and because "Retain
Extra Versions" is set to "No Limit," am I correct in deducing that
TSM will keep three copies of deleted files forever, because "Retain
Only Version" will never become relevant?

Or does TSM use "Retain Only Version" for all versions (copies) once
there isn't an active file? (That's not what the doc says, of course.)

Thanks,
