Replicating automated backups to another Amazon Web Services Region
For added disaster recovery capability, you can configure your Amazon RDS database instance to replicate snapshots and transaction logs to a destination Amazon Web Services Region of your choice. When backup replication is configured for a DB instance, RDS initiates a cross-Region copy of all snapshots and transaction logs as soon as they are ready on the DB instance.
DB snapshot copy charges apply to the data transfer. After the DB snapshot is copied, standard charges apply to storage in the
destination Region. For more details, see RDS Pricing
For an example of using backup replication, see the Amazon online tech talk Managed Disaster Recovery with Amazon RDS for Oracle Cross-Region Automated Backups
For information about configuring and managing automated backups for Amazon RDS, see the following topics.

Region and version availability
Feature availability and support varies across specific versions of each database engine, and across Amazon Web Services Regions. For more information on version and Region availability with cross-Region automated backups, see Supported Regions and DB engines for cross-Region automated backups in Amazon RDS.

You can also use the describe-source-regions Amazon CLI command to find out which Amazon Web Services Regions can replicate to each
other. For more information, see Finding information about replicated backups for Amazon RDS.
Limitations
Following are limitations for cross–Region automated backups for Amazon RDS.
Automated backup replication is not supported for Multi-AZ DB clusters.
By default, you can have up to 20 cross–Region automated backups per Amazon Web Services account.
