These backups can also be used to support making copies of your database to be used in a different account or region. This is also called cross-region or cross-account cloning. Let's start by looking at RDS automated backups in more depth.

AWS manages standard backups for you unless you specifically configure it not to. The backups are taken when the database is running, and they do not cause any downtime.
