sorry again

you said  bkp_restore –m backup_config is incremental, I cant agree with
that, the docs specifically says backup_config performs a full configuration
backup and that is what confuses me, if I have a full ORACLE_HOME backup why
on earth I would have to do a backup_config after the full backup?
