Oracle RMAN - Configure advanced RMAN backups and scripts

Learn how RMAN configuration parameters govern startup, backup, and recovery behavior; connect to the target database via slash or user/password, guided by environment variables, and view settings with show all.

Explore how RMAN configuration parameters govern backups, including default channels, retention policy, redundancy vs recovery window, backup optimization, and default device types, and how script overrides affect behavior.

Configure RMAN parameters to enable control file backups, set formats, device types, channels, and parallelism, manage backup copies, retention, encryption, compression, archive deletion, and snapshot control file naming.

Explore RMAN channels and parallelism to optimize backups and scripts, building on RMAN configuration parameters and deepening your understanding of parallel execution.

Explore how RMAN uses automatic and manual channels, plus the auxiliary channel, in backups and cloning, and define channels in an RMAN script block.

Configure the default device type as disk with parallelism 1 to use RMAN channels by default, and understand archivelog, archive destination, and backup sets and pieces.

Configure the RMAN channel with parallelism 2 to use two channels for backups and observe how backup pieces are allocated; cross-check backups and note channel count depends on CPU cores.

Configure a default channel to automatically route backups to a specified disk location, using a device type disk and a custom format for backup pieces.

Explore the different RMAN backup types, learn what constitutes a backup and which files to back up, and identify the key RMAN components essential for recovery.

Discover how RMAN performs physical backups by backing up parameter file, control files, data files, and archive logs to enable recovery from mount to open.

Learn the two backup types: consistent backups capture the database as it was at the backup time, and inconsistent backups require applying archive logs to recover changes with RMAN.

Explore full backups and incremental backups, including level 0 and level 1, and compare differential and cumulative backups to optimize recovery with archives and redo logs.

Learn RMAN backups and scripts, including full, incremental, compressed, and archive log backups, with guidance on destinations, channels, disk space, control file and SPFILE backups.

Learn to take a full RMAN database backup, configure a default disk channel, and back up data files, control file, and archived logs to a defined location.

Master RMAN backups by configuring multiple channels, setting custom destinations, and using run blocks to parallelize archive log and data file backups.

Learn to perform RMAN incremental backups, including level 0 and level 1 backups, specifying a user-defined location and using multiple channels to run parallel backups.

Learn how to check RMAN backups by listing backup keys, types (full, level 0, level 1), tags, and pieces, and understand backup location, device type, size, and status.

Learn to take compressed backups with RMAN to save disk space. Use the backup as compressed backup set command, enable default compression, and verify backup sizes.

Learn how RMAN manages archivelog backups, including listing and verifying archived logs, backing up all archivelogs, and deleting disk archives after successful backups to maintain space.

Learn how RMAN deletes archivelog backups while cross-checking backups against disk and control file, identifies missing or deleted archives, and explains expired and obsolete backups under a retention policy.
