RMAN

RMAN (Recovery Manager) is a backup and recovery manager supplied for Oracle databases (from version 8) created by the Oracle Corporation.^[1] It provides database backup, restore, and recovery capabilities addressing high availability and disaster recovery concerns. Oracle Corporation recommends RMAN as its preferred method for backup and recovery and has written command-line and graphical (via Oracle Enterprise Manager) interfaces for the product.

Implementation

The designers of RMAN aimed at integration with Oracle database servers,^{[citation needed]} providing block-level corruption detection during backup and restore processes.^{[citation needed]} RMAN optimizes performance and space-consumption during backup with file multiplexing and backup-set compression; it integrates with Oracle Secure Backup and with third-party media management products for tape backup.

The syntax system of many commands and options allows database administrators to fine-tune the methods and performance of backups and restores of Oracle data and Oracle configuration information.^[2]

"Complete recovery" entails restoring all available consistent information to the most current time. "Incomplete recovery" options allow specifying restoration to a given time in the past.^[3] It can also restore a specific tablespace (group of database objects) or a specific table.

RMAN can use a defined "fast recovery area" (originally called the "flash recovery area") for backup and recovery data.^[4]
