A company must enforce new data retention policies for all databases running on Amazon RDS DB instances: retain daily backups for a minimum of 2 years, with backups consistent and restorable. Which solution should a solutions architect recommend?

AWS Backup is the most suitable solution for managing backups across multiple AWS services, including Amazon RDS. By creating a backup vault and a backup plan with a daily schedule and a 2-year retention policy, the company can centralize and automate the backup process, ensuring compliance with the data retention policies. Assigning the RDS DB instances to this backup plan ensures all specified databases are covered. Incorrect options: Configuring a backup window and snapshot retention on RDS instances, then using Amazon DLM, is less centralized and more complex than AWS Backup for managing retention across multiple instances. DLM is primarily for EBS snapshots. Backing up transaction logs to CloudWatch Logs does not provide a consistent, restorable database backup; it only captures log data, not the full database state. AWS DMS with CDC to S3 streams changes, which is useful for replication or analytics, but it doesn't create consistent, restorable database backups in the traditional sense required for long-term retention and recovery. S3 Lifecycle policies would manage S3 object deletion, not database restorable backups.
