Amazon RDS is a web service that allows to set up, operate, and scale a relational database. With Amazon RDS one can create a storage volume snapshot of your DB instance. Configured with AWS Backup service, AWS RDS can automate backing up plans for an entire DB instance by configuring a scheduled backup plan. We identified that the Backup service does not back up the RDS Snapshot instance '{AwsRdsDbInstanceSnapshot}'. Best practice is to ensure that RDS Snapshot instances are integrated into the Backup service to improve reliability.
