AWS S3 Glacier
AWS S3 Glacier is a secure, durable, and low-cost cloud storage service for data archiving and long-term backup, designed for infrequently accessed data. It is part of the Amazon S3 storage family, offering retrieval times ranging from minutes to hours depending on the access tier. It is ideal for regulatory compliance, digital preservation, and disaster recovery scenarios where data must be retained for years.
Developers should use AWS S3 Glacier when they need to store large volumes of data for long periods at minimal cost, such as for legal archives, medical records, or historical logs. It is particularly useful in applications requiring compliance with data retention policies or when data is rarely accessed but must be preserved indefinitely. For example, backup systems, media archives, or scientific datasets benefit from its durability and cost-effectiveness.
