Oracle RAC Backups
You can back up online or offline Oracle RAC databases, log files, or Oracle datafiles and tablespaces. 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 run backups immediately or configure a schedule for the subclient.
Oracle full backups include the entire database and the control file. A full backup is the most comprehensive backup and is the baseline for incremental backups. Full backups of online databases include the log files. An offline full backup is a cold backup for Oracle databases.
An Oracle incremental backup contains the changed data from the last full backup. Incremental backups use less media and resources than full backups.
A cumulative backup backs up all blocks changed after the most recent incremental level 0 backup.
What is Backed Up
- Oracle database files that include the datafiles and control files
- Archived redo logs
- Parameter files (SP File)
- Oracle Managed Files
What Is Not Backed Up
Oracle application files that are associated with the Oracle installation.
External files, for example, Oracle Wallet, and external tables.
