Back up from Standby only

Starting with Oracle® 11.x, backups of datafiles, archived redo log files, Control Files, and SPFILE are interchangeable between the Primary and Standby Database Server. This interchangeability means that all backups can be performed from one of the Standby Database Servers. With this strategy, Plug‑in for Oracle is installed on both the Primary Database Server and at least one of the Standby Database Servers that performs backups. The plug-in must be installed on the Primary Database Server when it is targeted for a restore; that is, if you want to use the backup of the Standby Database Server to recover the Primary Database Server, you need to install the plug-in on the Primary Database Server.

Deployment

Plug‑in for Oracle’s support in Data Guard environments is restricted to physical standby databases. Logical and Snapshot standby databases are not supported. A physical standby database is a transactionally consistent copy of the production database. All references to standby databases see physical standby databases.

The plug-in supports the following types of Data Guard deployments:

Single-Instance

-->

Single-Instance

Multi-Instance RAC

-->

Single-Instance

Multi-Instance RAC

-->

Multi-Instance RAC

Deploying the plug-in in a Data Guard environment requires that you install the plug-in on the Primary Database Server and at least one of Physical Standby Servers — based on the backup strategy selected. For more information on selecting a backup strategy, see Defining a deployment strategy.

Single-instance to single-instance Data Guard deployment

In a single-instance to single-instance Data Guard deployment, the plug-in is installed on both the Primary and at least one of the Standby Database Servers.

Multi-instance RAC to single-instance Data Guard deployment

In a multi-instance to single-instance Data Guard deployment, the plug-in is installed in the Primary RAC Database environment and at least one of the Standby Database Servers.

For more information on deploying the plug-in in a multi-instance RAC environment, see Defining a deployment strategy.
