restoreDbInstanceFromS3

Amazon Relational Database Service (Amazon RDS) supports importing MySQL databases by using backup files. You can create a backup of your on-premises database, store it on Amazon Simple Storage Service (Amazon S3), and then restore the backup file onto a new Amazon RDS DB instance running MySQL. For more information, see Restoring a backup into an Amazon RDS for MySQL DB instance in the Amazon RDS User Guide.

This operation doesn't apply to RDS Custom.
