RAC One Node provides higher availability by eliminating the database server as a single point of failure.
Oracle Recovery Manager satisfies the most pressing demands of performant, manageable backup and recovery, for all Oracle data formats.
A complete high availability and disaster recovery strategy requires dependable data backup, restore, and recovery procedures. Oracle Recovery Manager (RMAN) provides a comprehensive foundation for efficiently backing up and recovering the Oracle database. It is designed to work intimately with the server, providing block-level corruption detection during backup and restore. RMAN optimizes performance and space consumption during backup with file multiplexing and backup set compression, and integrates with Oracle Secure Backup, as well as third party media management products, for tape backup.
RMAN takes care of all underlying database procedures before and after backup or restore, freeing dependency on OS and SQL*Plus scripts. It provides a common interface, via command line and Enterprise Manager, for backup tasks across different host operating systems and offers features not available through user-managed methods, such as parallelization of backup/restore data streams, backup files retention policy, and detailed history of all backups.
RMAN is also used to facilitate migrations on-premises and to the Oracle Cloud. For complete details related to Oracle Cloud migration with RMAN visit the Oracle Cloud Infrastructure documentation for Migrations Databases to the Cloud.
Each Oracle database release comes with enhancements to Recovery Manager. For the latest list of enhancements visit the Backup and Recovery Reference.
