Explanation

Setting the RDS backup retention policy to 30 days forautomated backupsthrough AWS Backup allows the company to retain backups cost-effectively. Manual backups, however, are notautomatically managed by RDS's retention policy, so they need to be manually deleted if they are older than 30 days to avoid unnecessary storage costs. Key AWS features: Automated Backups: Can be configured with a retention policy of up to 35 days, ensuring that older automated backups are deleted automatically. Manual Backups: These are not subject to the automated retention policy and must be manually managed to avoid extra costs. AWS Documentation: AWS recommends using backup retention policies for automated backups while manually managing manual backups.
