Deploying the Recovery Appliance in a Data Guard Configuration
(Doc ID 2412431.1)
Last updated on MARCH 12, 2021
Applies to:Zero Data Loss Recovery Appliance Software - Version 220.127.116.11.6 and later
Information in this document applies to any platform.
This best practice paper is intended for a technical audience wishing to deploy Recovery Appliances in multiple locations that also host Data Guard configurations:
- Data Guard is used to provide High Availability (HA) and disaster protection by enabling immediate failover to a synchronized copy at a second location should a database or site go offline.
- Recovery Appliances are deployed at each location to provide local backup and recovery for databases hosted at that location – including Data Guard primary or standby databases.
- Finally, because a Data Guard physical standby database is an exact copy of production, real-time backups taken by either Recovery Appliance can be used to restore primary or standby databases at either location should a local appliance be unavailable.
The recommendations included in this paper result in achieving the optimal level of HA and data protection while conserving network bandwidth. All procedures described in the following sections apply equally to either Data Guard or Active Data Guard physical standby databases
