Use Standby Databases with Autonomous Data Guard for Disaster Recovery

When you add an Autonomous Data Guard standby database, Autonomous Database provides data protection and disaster recovery for your database.

Autonomous Database Disaster Recovery Options

Autonomous Data Guard: 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 cross-region standby.

You can also create an Autonomous Data Guard standby in a different tenancy.

Autonomous Data Guard is available for the following workload types:
- Data Warehouse
- Transaction Processing
Backup-Based Disaster Recovery: uses backups to instantiate a peer database at the time of switchover or failover. This enables you to have a lower cost and higher Recovery Time Objective (RTO) disaster recovery option for your Autonomous Database, as compared with Autonomous Data Guard. For local Backup-Based Disaster Recovery, existing local backups are utilized. There are no additional costs for a local Backup-Based Disaster Recovery. Cross-Region Backup-Based Disaster Recovery incurs an additional cost. See Use Backup-Based Disaster Recovery for details on Backup-Based Disaster Recovery.

Backup-Based Disaster Recovery is available for all workload types.
