# Configuring Cross-Region Copy of an Amazon RDS Snapshot in the Same Account

You can copy Amazon RDS snapshots to a different geographic region in the same cloud account. To do so, you need to create a secondary snapshot copy and add the mapping from source region to the target region. By default, if you don't map the source region to the target region, the target region is mapped to be the same region as the source region of the snapshot. Replication will be automatically enabled on the instance.

## Before You Begin

- If the source Amazon RDS instance is using a Custom Option Group, then verify that a Custom Option Group with the same name and parameters exists in the destination region.

- If the AWS RDS Database is KMS encrypted, ensure that it meets the KMS Key Permission Requirements for Amazon RDS Using Snapshot.

   The Overview page appears.

2. On the Instances tab, click the instance.

    - To select a specific date, select Protect from a specific date and then set the Start time.

11. For the Retention rules, select either Retention period or Number of snap recovery points, and then add the rules.

12. To specify additional backups, such as weekly full backups, move the Extended Retention rules toggle key to the right, and then add rules.

13. To add mappings, in the Mappings field, click Add.
