Greetings, I have been following the discussion re autobackup of the controlfile and as a result have been doing some investigation and still have one question. I don't understand what additional safety is provided by doing an autobackup of the controlfile as opposed to BACKUP CURRENT CONTROLFILE as the last step of the backup procedure. I realize that the spfile is backed up as part of the autobackup and as I understand it changes to database structure cause the controlfile and spfile to be backed up (or so the docs say). But if I have the backup piece containing the controlfile and can restore a controlfile from. I've done that. Is the added protection of having an spfile and controlfile in sync the primary gain or are there other pieces I am missing? Thanks.
