What is the method for backing up tables in Oracle?
There are several methods for backing up tables in Oracle.
- Backing up tables using Oracle Data Pump tool: Data Pump is an efficient tool provided by Oracle database that can export tables in binary format into one or multiple files. You can use the expdp command to export tables and the impdp command to import the exported table data into the database.
- Utilize Oracle’s traditional export and import tools to back up tables: The traditional export and import tools allow tables to be exported in text format into one or multiple files. Export tables using the exp command, and import the exported table data into the database using the imp command.
- Backing up tables with Oracle RMAN: RMAN (Recovery Manager) is a backup and recovery tool provided by Oracle database. It can be used to backup data files and control files of tables, as well as the corresponding archive log files.
- Utilizing Oracle physical backup and recovery allows for using methods like Cold backup (backing up data files while the database is shut down) or Hot backup (backing up data files while the database is running) to back up table data.
- Utilizing Oracle logical backup and recovery involves using Oracle’s logical backup methods, such as expdp and exp commands, to backup table data.
Regardless of the backup method you choose, it is important to consider factors such as the frequency, storage location, completeness, and consistency of the backup to ensure its reliability and recoverability.
