Amazon S3 Glacier is designed for data archiving, offering very low storage costs for long-term archiving where data is infrequently accessed. Its retrieval times can be slow (from minutes to hours), which aligns with the company's requirements for rare access and is acceptable in the case of legal issues. Amazon S3 Standard offers higher availability and faster access but at higher costs and is not suitable for archiving. Amazon S3 Intelligent-Tiering is designed to optimize costs by automatically moving data to the most cost-effective access tier, but has a monitoring and automation cost, making it less attractive for purely archival information. Amazon S3 One Zone-Infrequent Access provides a lower-cost option compared to Standard, but still costs more than Glacier and is most effective when you need quicker access to infrequently accessed data.
