Back up Oracle databases, datafiles, tablespaces, and archive logs by using Oracle Recovery Manager (RMAN).
Use a database subclient to back up database data and a log subclient to back up archive logs.
You can back up a database when it is online or offline. If the database must remain accessible and you have a limited backup window, run online backups for different database portions.
Backup types
You can run full, incremental, or cumulative backups. An incremental backup contains data that changed after the last successful backup. If no backup completed successfully, an incremental backup is considered a full backup and includes all data.
Note
Database log files are not deduplicated, even if a backup plan used to back up log files specifies deduplication.
Incremental backups use fewer resources than full backups. If you do not have any successful backups and you perform an incremental backup, the incremental backup is considered a full backup and all data is backed up.
