# Backing Up a Database for Amazon RDS for Oracle

You can perform a full backup or an incremental backup operation of an Oracle database or the archive logs.

You can also perform a logical data pump backup of the Amazon RDS data. When you perform a backup operation on a logical subclient, the Commvault software invokes the Oracle data pump export utility to create a dump file of tables, and then places the file in the specified staging path on the proxy server.

## Prerequisites

- Commvault sets the default retention time to 48 hours. If you want a greater retention time for the archive logs, the DBA must modify the retention settings before the first backup is made. The DBA can set the retention time with code similar to the following. For example, to set the retention to 96 hours, use the following commands:

      begin rdsadmin.rdsadmin_util.set_configuration( name => 'archivelog retention hours', value => '96'); end; / commit;

- Verify the following on destination client for logical dump subclient data backup:

  - Oracle version must match AWS RDS Oracle version.

  - Oracle database on the access node must be running.

  - Discover the proxy Oracle instance on Command Center.

## Procedure

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

   The databases Overview page appears.

2. On the Instances tab, click the instance.

   The instance page appears.

3. On the Subclients tab, click the subclient.

   The subclient properties page appears.

4. In the upper-right area of the window, click Backup.

   The Backup options dialog box appears.

5. Select the backup level for the backup operation:

   - To perform a full backup operation, select Full.

   - To perform an incremental backup operation, select Incremental.

6. Click SUBMIT.
