# Replicating automated backups to another AWS Region
<a name="USER_ReplicateBackups"></a>

For added disaster recovery capability, you can configure your Amazon RDS database instance to replicate snapshots and transaction logs to a destination AWS 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](https://aws.amazon.com/rds/oracle/pricing/).

For an example of using backup replication, see the AWS online tech talk [Managed Disaster Recovery with Amazon RDS for Oracle Cross-Region Automated Backups](https://pages.awscloud.com/Managed-Disaster-Recovery-with-Amazon-RDS-for-Oracle-Cross-Region-Automated-Backups_2021_0908-DAT_OD.html).

**Note**  
Automated backup replication isn't supported for Multi-AZ DB clusters. However, it is supported for Multi-AZ DB instance deployments. For more information about limitations for automated backups, see [Quotas and constraints for Amazon RDS](CHAP_Limits.md).

## Multi-AZ deployment support
<a name="USER_ReplicateBackups.Multi-AZ-deployments"></a>

Cross-Region automated backup replication is supported for Multi-AZ DB instance deployments for the following engines:
+ RDS for Db2
+ RDS for MariaDB
+ RDS for MySQL
+ RDS for Oracle
+ RDS for PostgreSQL
+ RDS for SQL Server

Cross-Region automated backup replication isn't supported for Multi-AZ DB clusters.

## Region and version availability
<a name="USER_ReplicateBackups.RegionVersionAvailability"></a>

Feature availability and support varies across specific versions of each database engine, and across AWS 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](Concepts.RDS_Fea_Regions_DB-eng.Feature.CrossRegionAutomatedBackups.md). 

## Source and destination AWS Region support
<a name="USER_ReplicateBackups.Regions"></a>

Backup replication is supported between the following AWS Regions.
