Disaster Recovery (DR) solution for RDS Oracle

Hi,

Here are the cross-region Disaster Recovery options available for RDS Oracle for you :-

1. DR with RDS for Oracle cross-Region mounted DB replicas : Suitable for RPO and RTO of few minutes. It requires only Oracle EE license on the replica. Oracle Data Guard is included with Oracle EE
2. DR with RDS for Oracle cross-Region read replicas : Suitable for RPO and RTO of few minutes. However, this option requires Oracle EE and Active Data Guard licenses
3. DR with RDS for cross-Region Automated Backups : PITR using cross-Region Automated Backups may lead to RPO of 25 minutes approximately and RTO in hours.

You may chose the option suitable to you based on the RPO/RTO requirements and cost considerations.
