This document details the RMAN backup procedure for Oracle Database, outlining methods for both offline (consistent) and online (inconsistent) backups.
- Consistent Backup (Offline): Requires database downtime. The database must be shut down cleanly, causing application outage. Not ideal for production environments due to downtime.
- Inconsistent Backup (Online): Performed while the database remains online and accessible. Requires the database to operate in ARCHIVELOG mode to preserve transactional integrity.
