The correct answer is Amazon RDS Automated Backups, as it directly supports the backup of database instances, allows for a retention period selection (up to 35 days), and facilitates relatively quick data restoration when compared to alternatives like manual snapshots or custom backup solutions. Amazon RDS Automated Backups are more cost-effective and practical for daily database backups with a one-month retention period, given the operational recovery requirements. In contrast, Amazon S3 Standard is an object storage solution not specialized for database backups and could incur higher costs and complexity in managing database consistency. Amazon EBS Snapshots would require manual intervention and management for databases, making it a less integrated solution. Although using Amazon Glacier is cost-efficient for long-term storage, its retrieval times are typically in the hours range, which doesn't meet the requirement for quick restoration.
