RMAN
RMAN (Recovery Manager) is a command-line tool provided by Oracle for database backup, recovery, and duplication. It automates and manages backup and restore operations for Oracle databases, supporting features like incremental backups, compression, and encryption. RMAN integrates directly with the Oracle database server to ensure data consistency and reliability during these operations.
Developers and database administrators should learn RMAN when working with Oracle databases to ensure data protection, disaster recovery, and compliance with backup policies. It is essential for scenarios requiring point-in-time recovery, cloning databases for testing, or migrating data between environments, as it minimizes downtime and reduces the risk of data loss.
