Database Backup (DBS) allows you to perform physical backup for Windows or Linux Oracle databases of multiple architectures such as singe-instance, Data Guard physical standby, and Real Application Clusters (RAC).
Prerequisites
- The Oracle database to be backed up is running in archive mode. For more information, see Enable the archive mode.
- The Oracle System ID (SID) is obtained. For more information, see Obtain the Oracle SID.
- A backup gateway is installed on the server where the database to be backed up is deployed. For more information, see Add a backup gateway.
Oracle architectures that support physical backup
This topic describes the physical backup of Oracle databases. For more information about logical backup, see Back up an Oracle instance by using logical backup.
- Single-instance Oracle databases
- Automatic Storage Management (ASM)-based single-instance Oracle databases
- Oracle Data Guard physical standby
- Oracle RAC
Note
- To perform a successful backup, you must check the control files, SPFILEs, data files, archived log files, and redo log files of Oracle databases before you back up the data. For more information, see Query the locations of files in an Oracle RAC environment.
- To back up the entire RAC, you need only to deploy a backup gateway on one of the servers where the Oracle RAC database is deployed and enter the Oracle SID of the server.

What to do next
DBS allows you to restore an Oracle database to a different machine, to a different directory of the source machine, or to the same directory of the source machine. For more information, see Restore an Oracle database from a physical backup.
