A company is using AWS to host their databases. They are required by regulatory standards to maintain backups for seven years. The databases are not modified frequently. How should the company set up their backup and retention policy to optimize costs?
Take daily backups and transition the backups to Amazon Glacier Deep Archive after 30 days for long-term storage.
Take daily backups and store all of them in Amazon S3 Standard for the required seven-year retention period.
Take backups every hour and keep them in Amazon S3 Standard-Infrequent Access for the full seven years.
Take weekly backups and store them in Amazon S3 Standard for seven years without transitioning to any other storage class.
