Rman tool is the best for Backup
Oracle date backup choices include user-managed backups, Oracle Recovery Manager and import/export backups. Depending on your needs and your budget, all three Oracle backup strategies could be suitable for your environment.
Oracle Recovery Manager (RMAN)
RMAN
Recovry Manager (RMAN) is best tools for physical backup
Hello,
Oracle Recovery Manager (RMAN): a command-line is the Oracle-preferred method for efficiently backing up and recovering Oracle Database. RMAN is designed to work intimately with the server, providing block-level corruption detection during backup and recovery. RMAN optimizes performance and space consumption during backup with file multiplexing and backup set compression, and integrates with leading tape and storage media products with the supplied Media Management Library.
Oracle Data Pump : Physical backups can be supplemented by using the Oracle Data Pump (export/import) utilities to make logical backups of data. Logical backups store information about the schema objects created for a database. Oracle Data Pump loads data and metadata into a set of operating system files that can be imported on the same system or moved to another system and imported there.
Good Luck.
