Amazon Relational Database Service (RDS) for SQL Server now has the capability to perform Cross Region Automated Backups with encryption.
This feature provides disaster recovery for important databases, as you can restore the database to a past point in time within the retention period. In the event that the main AWS Region is inaccessible, this feature allows you to quickly resume operations. Moreover, if encryption was enabled on the source RDS for SQL Server DB instance, you can use this feature to transfer encrypted DB snapshots to regions outside of the primary AWS region.
