Oracle Backup and Recovery Solutions
When implementing a backup and recovery strategy, you have the following solutions available:
*
Recovery Manager (RMAN)
Recovery Manager is fully integrated with the Oracle database to perform a range of backup and recovery activities, including maintaining an RMAN repository of historical data about backups. You can access RMAN through the command line or through Oracle Enterprise Manager.
*
User-managed backup and recovery
In this solution, you perform backup and recovery with a mixture of host operating system commands and SQL*Plus recovery commands.You are responsible for determining all aspects of when and how backups and recovery are done.
These solutions are supported by Oracle and are fully documented, but RMAN is the preferred solution for database backup and recovery. RMAN provides a common interface for backup tasks across different host operating systems, and offers several backup techniques not available through user-managed methods.
