You can back up Oracle RAC databases, log files, or Oracle RAC datafiles and tablespaces.
Note
Database log files are not deduplicated, even if a server plan used to back up log files specifies deduplication.
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, then run a series of online backups for different database portions.
