Scenario 4: Backup in target

  • Because the Oracle database backup is a resource-intensive operation, PowerFlex test failover can be used instead to perform backups using secondary storage without impacting production.

    1. Enable archive logging on the source to the FRA ASM disk group. In this configuration, FRA is also being replicated to the target.
    1. Start the Oracle database workload.
    2. Create remote snapshots, mount volumes on the target and start the database using the steps described in Scenario 3.

    Result: A new database instance is running on the target system which can be used for database backup using the RMAN command causing no impact to the production database performance.
