# Performing Oracle Backups

You can back up Oracle databases, log files, or Oracle datafiles and tablespaces. The system uses Oracle Recovery Manager (RMAN) for these backup operations.

You can back up the database when it is online or offline. If the database must be accessible and you have a small backup window, run a series of online backups for different database portions.

You can perform a full, incremental or cumulative backup. A full backup includes the database, the log files, and the control file. An incremental backup contains the changed data from the last successful backup.

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.
