S3 Glacier Storage Classes
The following S3 Glacier Storage Classes are available for now:
- GLACIER - (S3 Glacier Flexible Retrieval, formerly S3 Glacier) - For long-term backups and archives with retrieval option from 1 minute to 12 hours
- GLACIER_IR - (S3 Glacier Instant Retrieval - For long-lived archive data accessed once a quarter with instant retrieval in milliseconds)
- DEEP_ARCHIVE - (S3 Glacier Deep Archive) - For long-term data archiving that is accessed once or twice in a year and can be restored within 12 hours
The GLACIER, GLACIER_IR and DEEP_ARCHIVE differ from other storage classes. They was designed for data that will be stored for decades without the need to access. As of Aug 2022, these are the cheapest storage classes on AWS. You pay when you need to access your data (see the pricing for more details).
The data you store under the GLACIER and DEEP_ARCHIVE storage classes is not available for real-time access. You need to restore the objects before you access them. Please check out instructions below for more details on how to restore the files stored under the GLACIER storage class.
The GLACIER_IR storage class offers immediate access to the data. The restore is not required for downloading the data.
In order to move your object to the GLACIER or DEEP_ARCHIVE storage classes you need to configure Bucket Lifecycle Rules. There is no way to apply these storage classes during uploading.
Starting from Nov 26, 2018, direct uploads to the GLACIER, GLACIER_IR and DEEP_ARCHIVE storage classes are possible, please check out the instructions below.
The GLACIER, GLACIER_IR and DEEP_ARCHIVE storage classes offer the same durability and resiliency as STANDARD.
