A backup cannot be recreated and must be retained for a long time.
Access is infrequent, but retrieval should be available in milliseconds and the data should be resilient to an AZ loss.
Which S3 storage class should be considered?
S3 Standard-IA is designed for long-lived, infrequently accessed data that still needs millisecond access and multi-AZ resilience.
Detailed explanation
Standard-IA suits long-lived, infrequently accessed data that needs rapid retrieval and multi-AZ resilience.

One Zone-IA stores data in one AZ and has lower resilience to an AZ failure than Standard-IA.

S3 Standard is general purpose, but ignoring the access and retention pattern can miss a better cost and lifecycle choice.

Foundation review
Class selection
Storage class choice combines access pattern, retrieval requirement, resilience, and cost.
Lifecycle transition
Lifecycle rules can move objects between classes as the access pattern changes.
