Oracle Database 19c Backup and Recovery

Explore Oracle database backup and recovery concepts, including full, incremental, differential, online and offline backups, RMAN strategies, image copy and backup set, and data guard options.

Learn RMAN backup and recovery concepts, including image copy vs backup set, full and incremental backups, data, control, and archive logs, with OEM integration and compression options.

Learn how to multiplex the control file by keeping multiple control files in separate storage, add a third via a pfile to start the database with an spfile.

Configure the fast recovery area in Oracle 19c by setting the db recovery file destination and dynamically resizing from 12 gb to a chosen size, and verify archive log activity.

Learn how to multiplex redo log files in Oracle Database 19c, why two members per group matter, and how archive log mode and fast storage affect performance and recovery.

Configure an Oracle 19c database in archivelog mode by enabling archiving, verifying status, and performing shutdown, mount, and startup steps to ensure recoverability.

Configure and verify the default backup destination, then perform a database backup using a dedicated backup user, ensuring old backups and archive logs are cleaned from the fast recovery area.

Configure RMAN settings to implement retention policies, redundancy, and backup optimization, and use show commands and report schema to tailor device type, parallelism, and backup copies.

Back up the control file by generating a trace with alter database backup control file to trace, then use the resulting SQL to recreate it if needed.

Connect to RMAN and verify that control file auto backup is on; demonstrate that backups include the SPFILE and all control files during a database backup across CDB and PDBs.

In oracle database 19c, perform a whole database backup that includes archive logs, sp file, and control files, either online (hot) or offline, with separate backups for CDB and PDBs.

Explore partial backups in Oracle Database 19c using RMAN, backing up a pluggable database and specific tablespaces with archived logs, and handling container connections.

Enable block change tracking to speed incremental backups by tracing changed blocks since the last backup, under the eight bitmap limit, and level zero and level one incrementals use bitmap.

Learn how blockchain tracking accelerates incremental backups by creating an image copy for level zero, applying level one changes, and validating with a practical table space setup.

Learn how to perform archival backups beyond normal retention, including keep forever requirements with a recovery catalog, and storing backups off fast recovery area for long-term retention.

Monitor RMAN backup progress with the Long Ops view, tracking percentage complete, sessions, and completion status for full, differential, incremental, cumulative, partial, and archival backups via a sample query.

Learn how to create a recovery catalog in Oracle 19c, register production databases, and manage backups from the catalog database with a dedicated user and tablespace.

Create a recovery catalog to manage backups across multiple databases from a single location, using RMAN and a recovery catalog owner account to run the create catalog command.

Register databases in the recovery catalog and verify the registration status. Use the catalog to manage backups and recoveries for CDB, PDB, and non-CDB databases.

Configure the recovery catalog for backup and recovery, set a redundancy retention policy, enable archive log and fast recovery area, and perform image copy and incremental backups for databases.
