Is it required to maintain the archive log? If I have a valid backup of the full database up to 9 p.m., and my daatabase failed at 12 p.m., and I have the archive log of three days' data, and up to this second a valid archive log... in this case, for recoving a database is the old archive backup (from the date of database creation) required or not?
In order to recover the database, you'll need your most current backup and all archived logs generated since that backup. The system will not use archived logs older than your backup for recovery. This assumes you want to recover as much data as possible.
