An employee at a healthcare facility is tasked with storing 7 years of patient information that is rarely accessed. Their boss wants them to consider one of the Amazon S3 storage tiers to store the information. Which storage tier should they use?

S3 Glacier Deep Archive is the lowest-cost Amazon S3 storage class. It supports long-term retention and digital preservation for data that might be accessed once or twice a year. It is designed for customers—particularly those in highly regulated industries, such as the financial services, healthcare, and public sectors. These customers often retain data sets for 7–10 years or longer to meet regulatory compliance requirements.
