Optional RMAN configuration settings

The following settings are optional in a Data Guard environment.

RMAN’s Retention Policy specifies a persistent, ongoing policy for backup sets and copies those sets that RMAN marks as obsolete, that is, not needed and eligible for deletion. As time passes, RMAN marks backup sets and copies as obsolete according to the criteria specified in the retention policy. RMAN automatically deletes obsolete backup sets and copies in the FRA when space is needed. RMAN does not automatically delete obsolete files outside the FRA, such as on NetVault Backup backup media.

> rman TARGET / CATALOG rman/<password>@<connect_identifier for catalog>

RMAN’s Archive Log Deletion Policy specifies that archived redo logs are eligible for deletion if both of the following conditions are met:

The logs are not needed by the BACKED UP … TIMES TO DEVICE TYPE deletion policy. If the BACKED UP policy is not set, this condition is always met.
> rman TARGET / CATALOG rman/<password>@<connect_identifier
for catalog>

RMAN Backup Optimization prevents RMAN from backing up a file to a device type if the identical file is already backed up on the backup media. However, RMAN does not signal an error if backup optimization causes all files to be skipped during a backup.

> rman TARGET / CATALOG rman/<password>@<connect_identifier for catalog>
IMPORTANT: In a switchover or failover where the databases change roles, the corresponding CONFIGURE commands must be re-run on the new primary and standby databases.

Installing or upgrading the plug-in

In a Data Guard environment, you must install the plug-in on the Primary Database Server. Optionally, you can also install the plug-in on one or more Physical Standby Database Servers. For more information on the supported Data Guard deployments, see Deployment.

From the WebUI on the NetVault Backup Server, open the Manage Clients page. Add the NetVault Backup Clients installed on the primary and standby databases to the NetVault Backup Clients list.

Backing up data

RMAN-based backups are the only supported backup method for Data Guard environments. RMAN is Data Guard-aware in that it uses its metadata to behave transparently across the primary and physical standby databases in the Data Guard environment.

Performing backups in a Data Guard environment is almost identical to performing backups for a single- or multi-instance database in a non-Data Guard environment. The differences are described in the following topics.

For more information on selecting data for backup, setting backup options, and finalizing and submitting the job, see Performing RMAN backups.

Creating a User Defined Backup Tag

When a Data Guard strategy of backing up from both the Primary and Standby Database Server is implemented with backups from the Primary and Standby Database Servers being interchangeable, you might want to be able to select the source of the backup during a restore. For example, you might want to restore from the Primary Database Server versus the Standby Database Server. The User Defined Backup Tag option lets you assign a tag to the backups that indicates the source of the backup — the Primary Database Server or the Standby Database Server. During the restore, the User Defined Backup Tag is specified in the Restore Options to ensure that only backups from the applicable server are used for the restore.

1
On the NetVault Backup Plugin Options page, click the RMAN Backup Options tab.
2
Select the User Defined Backup Tag option, and enter a tag name.
