Amazon RDS on AWS Outposts now supports backups on AWS Outposts

Amazon Relational Database Service (Amazon RDS) on AWS Outposts now supports creating backups locally on AWS Outposts with Amazon S3 support. You can create backups of your Amazon RDS databases running on AWS Outposts to the same Outpost or to the AWS Region of your Outpost, allowing you to maintain your data residency requirements while giving you flexibility for maintaining your data recovery solutions. CloudFormation support will be coming soon.
