Dell Avamar for Oracle 19.10 User Guide

Data Domain system support

The Avamar Plug-in for Oracle supports backups to and restore from Data Domain systems. You can back up Oracle data to a Data Domain system by using Avamar Administrator or by using RMAN backup scripts. The Avamar Plug-in for Oracle stores the metadata for the backup on the Avamar server.

Before you can store backups on a Data Domain system, you must add the Data Domain system to the Avamar configuration by using Avamar Administrator. After you configure the Data Domain system, you can back up Oracle database files to the Data Domain system by performing the following actions:

• Selecting the appropriate plug-in option from Avamar Administrator.

• Specifying the Data Domain system as the target system for RMAN backup scripts.

You can also specify a Data Domain system when you create a dataset for a scheduled backup.

You must store the full backup for a client and all subsequent incremental backups on either the Avamar server or a single Data Domain system. The Avamar Plug-in for Oracle does not support backups that are stored partly on Avamar and partly on a Data Domain system. For example, the Avamar Plug-in for Oracle does not support the following types of backups:

• Full backup on a Data Domain system and incremental backups on the Avamar server
• Full backup on the Avamar server and incremental backups on a Data Domain system
• Full backup on one Data Domain system and incremental backups on another Data Domain system

If you change the device on which backups for a client are stored, you must then perform a full backup before you perform any further incremental backups.

The steps to restore backups are the same whether you restore backups from the Avamar server or from a Data Domain system. The restore process determines the location of the backup.

The Avamar and Data Domain System Integration Guide provides more information about configuring Data Domain systems for use with Avamar systems.
