Backing up and protecting databases enables recovery from an unplanned failure. Unplanned failures can represent significant risk to the business by stopping back-office operations, thus impacting revenue. In this test, we performed a restore from the Data Domain system backed up to the PowerEdge R740 servers. The goal of this test is to show a fast restore time of a 1 TB Oracle RAC database that has been protected in the Data Domain system.

In this use case, the total recovery time includes restoring the database from Data Domain using RMAN and opening the database for processing. Restore time alone does not represent that the database is open and available to the business. In this test, we showed that a 1 TB Oracle RAC database can be fully recovered from backup in less than 33 minutes.
