Using storage classes

Choose Intelligent-Tiering to optimize storage costs by automatically moving data to the most cost-effective storage access tier.

Objects smaller than 128 KB are not eligible for auto tiering in the Intelligent-Tiering storage class. These objects are charged at the frequent access tier rates, and don't incur the monitoring fee charged for auto-tiered objects.

S3 Intelligent-Tiering now supports an Archive Access tier and a Deep Archive Access tier. S3 Intelligent-Tiering automatically moves objects that haven’t been accessed for 90 days to the Archive Access tier, and after 180 days without being accessed, to the Deep Archive Access tier. Whenever an object in one of the archive access tiers is restored, the object moves to the Frequent Access tier within a few hours and is ready to be retrieved. This creates timeout errors for users or applications trying to access files through a file share if the object only exists in one of the two archive tiers. Don't use the archive tiers with S3 Intelligent-Tiering if your applications are accessing files through the file shares that are presented by the File Gateway.

When file operations that update metadata (such as owner, timestamp, permissions, and ACLs) are performed against files managed by the File Gateway, the existing object is deleted and a new version of the object is created in this Amazon S3 storage class. Validate how file operations impact object creation before using this storage class in production. See Amazon S3 pricing for more details.

Choose Standard-IA to store your infrequently accessed files redundantly in multiple Availability Zones that are geographically separated.

Objects stored in the Standard-IA storage class can incur additional charges for overwriting, deleting, requesting, retrieving, or transitioning objects between storage classes within 30 days. There is a minimum storage duration of 30 days. Objects deleted before 30 days incur a pro-rated charge equal to the storage charge for the remaining days. Consider how often these objects change, how long you plan to keep these objects, and how often you need to access them. Objects smaller than 128 KB are charged for 128 KB and early deletion fees apply.

When file operations that update metadata (such as owner, timestamp, permissions, and ACLs) are performed against files managed by the File Gateway, the existing object is deleted and a new version of the object is created in this Amazon S3 storage class. You should validate how file operations impact object creation before using this storage class in production because early deletion fees apply. See Amazon S3 pricing for more details.

Choose One Zone-IA to store your infrequently accessed files in a single Availability Zone.

Objects stored in the One Zone-IA storage class can incur additional charges for overwriting, deleting, requesting, retrieving, or transitioning objects between storage classes within 30 days. There is a minimum storage duration of 30 days, and objects deleted before 30 days incur a pro-rated charge equal to the storage charge for the remaining days. Consider how often these objects change, how long you plan to keep these objects, and how often you need to access them. Objects smaller than 128 KB are charged for 128 KB and early deletion fees apply.
