• Chose B2

  Amazon S3 Glacier Flexible Retrieval Key Benefits: Lowest storage cost among retrieval-capable storage classes. Designed for long-term archive where data is rarely accessed. Standard retrieval time: 3–5 hours, with the bulk retrieval option available within 5–12 hours. Ideal for use cases where retrieval can tolerate up to 12 hours of latency. Why Not Others? S3 Glacier Deep Archive: Even cheaper, but retrieval can take up to 48 hours, which does not meet the 12-hour requirement. S3 Standard-IA / S3 One Zone-IA: Faster retrieval, but higher storage costs. S3 Intelligent-Tiering: Useful for variable access patterns, but not the cheapest for archival-only use.

  S3 Glacier Flexible Retrieval: This storage class is designed for long-term archival of data that is infrequently accessed and where retrieval times of several hours are acceptable. It is the most cost-effective storage class for data that is retained for months, years, or decades. However, data retrieval times can range from a few minutes to several hours. S3 One Zone-Infrequent Access (S3 One Zone-IA): This storage class is designed for data that is infrequently accessed but requires rapid access when needed. It stores data in a single availability zone, which makes it less expensive than other S3 storage classes, but also less resilient to availability zone failures. Data retrieval is typically instantaneous. In the context of the question, if the company needs to access the data within 12 hours, both S3 Glacier Flexible Retrieval and S3 One Zone-IA could meet this requirement. However, S3 One Zone-IA would provide faster access times when the data is needed.
