RMAN and Data Pump which is more reliable?

Hi folks !

Plz let me know which is more efficent and reliable in terms of performance and security.

Thanks in advance

Never heard of both. What are they for?

Are these two both on backing up and recovering databases? I haven't encountered with this such tools yet.

you must use: expdp -help impdp -help to know all the options you can use when you make datapump. For more help,

Oracle Recovery Manager (RMAN), a command-line and Oracle Enterprise Manager-based tool, is the Oracle-preferred method for efficiently backing up and recovering an Oracle database. RMAN 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 and third-party media-management products for tape backup.

RMAN takes care of all underlying database procedures before and after backup or restore, removing dependency on OS and SQL*Plus scripts. It provides a common interface for backup tasks across different host operating-systems, and offers features not available through user-managed methods, such as parallelization of backup/recovery data streams, backup-files retention policy, and detailed history of all backups.
