+### Autonomous AI 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 all workload types.
+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 AI 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.
