# Specifying the Servers that Run Backups in an Oracle Data Guard Configuration

Applies to: An Oracle primary host and the standby host. A non-Oracle RAC standby host when you have created an Oracle Data Guard pseudoclient.

When you have an Oracle Data Guard configuration, you can specify whether the primary or standby host runs the data backups and log backups.

You can display the roles for the ArchiveLog subclient, but you can't change them. The ArchiveLog subclient roles are inherited from the Default subclient.

Note

If you preview the script generated for a Data Guard backup, it displays all the client nodes to run the backup on, based on the streams selected. However, when the backup actually runs, the primary or standby database roles configured on the subclient properties window are used to determine where the data and log backups run.

## Procedure

1. From the Command Center navigation pane, go to Protect > Databases.

   The database overview page appears.

2. On the Instances tab, click the instance.

   The instance properties page appears.

3. On the Subclients tab, click the subclient.

   The subclient properties page appears.

4. To specify where data and log backups run, do the following:

   1. In the lower-right area of the window, click Edit for the Oracle Data guard options.

   2. For the Data and Log backups, select the role from the Data list and from the Log list.

5. Click Save to save your selections.
