Autonomous Data Guard Autonomous Database
provides Autonomous Data Guard to enable a standby (peer) database to provide data protection and disaster recovery for your Autonomous Database instance.When you add an Autonomous Data Guard standby database, the system creates a standby database that continuously gets updated with the changes from the primary database. You can use Autonomous Data Guard with a standby in the current region, a local standby, or with a standby in a different region, a cross-region standby. You can also use Autonomous Data Guard with both a local standby and a crossregion standby.
