Amazon S3 Glacier is a low-cost cloud storage for data archiving. In fact, S3 Glacier seems so cheap that many users chose it for storing all their backups. That may be costly, though. Why?
Because Amazon Glacier is as cheap for data storage as it’s expensive for restore. This article explains the pricing for AWS’s least expensive storage class.

Amazon S3 Glacier Pricing
Amazon S3 Glacier pricing consists of 5 elements:
- Storage pricing. Starts at $0,004 per GB/month
- UPLOAD Requests. Each time you need to upload a file or a piece of file, a request is sent. Requests are billed in thousands, as there are usually many of them. The price is - $0.05/1000 UPLOAD requests.
- Retrieval Pricing. Before you can start downloading files, you need to retrieve them from Glacier. That is a special operation, that exists only for that Amazon S3 class.
- Retrieval Requests Pricing. Requests for retrieval operations.
- Transfer out pricing - this is a price for each GB you’ve downloaded out of the Glacier to Internet or to other AWS region. It has several tiers, and will be reviewed further in the article.
All prices depend on a region you work in. We are referring to the US East (N. Virginia) region.
Amazon S3 Glacier Early Deletion Fee
If you move or delete data in Glacier within 90-days since their creation, you will pay an additional charge, that is called an early deletion fee. In US East you will pay $0.004/GB if you have deleted 1 GB in 2 months, $0.008/GB if you have deleted 1 GB in 1 month and $0.012 if you have deleted 1 GB within 3 months. That’s effectively the same price for storing the given amount of data in a storage for a given time.

Amazon S3 Glacier Retrieval Cost
Data retrieval is a process of preparing your files for download. In Glacier this can be done in the range of minutes to 12 hours. The time depends on one of the three retrieval rates, you will choose:
- Expedited retrieval. You can access data within 1-5 minutes. The price for that rate is - $0.03 per GB plus additional $0.01 per request* or provisioned $100 per PCU**
- Standard retrieval. You can access your data in 3-5 hours. The price is - $0.01 per GB plus $0.050 per 1,000 requests
- Bulk retrieval. You can access the data in 5-12 hours. The prices are lowest among all retrieval rates - $0.0025 per GB plus $0.025 per 1,000 requests
*Expedited On-Demand requests, like EC2 On-Demand instances, are available the vast majority of the time.
**Provisioned requests should be used when you need a guarantee that your retrieval capacity will be available when you need it. You buy Provisioned requests in Provisioned Capacity units, each of which ensures at least 3 Expedited retrievals every 5 minutes and provides up to 150 MB/s of retrieval throughput.
You can retrieve 10 GB for free each month at standard speeds.

Once the retrieval is finished, you have 24 hours to transfer data out.
Amazon S3 Glacier Transfer Out Pricing
In AWS terms, when you download data from Glacier, you transfer data out. Price for transfer depends on whether you transfer data to the Internet or to other AWS region.
Data Transfer Out to Internet
- 1GB each month is free.
- 9.999 TB/ month - $0.09/ GB
- Next 40 TB/ month - $0.085/ GB
- Next 100 TB/ month - $0.07/ GB
- Greater than 150 TB/ month - $0.05/ GB
Data Transfer Out to AWS Regions is the same for all regions - $0.02/ GB
Data transfer in Glacier is always free.
Amazon S3 Glacier Deep Archive
Amazon Glacier Deep Archive storage class is meant for deep archival data that is only needed very infrequently but can’t be deleted. Basically, Glacier Deep Archive is an extension to the existing AWS Glacier service, but at a far lower price. The storage of 1Gb will cost you $0.00099 per month. According to AWS, this service is intended to replace tape that many companies still rely on.
In Amazon Glacier Deep Archive you won't have an option for an expedited data retrieval - the fastest retrieval time is up to 12 hours. The longest option - bulk retrieval - will take up to 48 hours.

How to Control Glacier Retrieval
MSP360 Backup lets you specify the required Glacier retrieval option. It allows you to choose exactly how you want to retrieve files - in Bulk, with Standard 3-5 hours or you need a fast but expensive Expedited restore.
You’re in Charge
If you have a well-planned data archival policy, Amazon S3 Glacier will quickly become the obvious and the cheapest solution on the market of cold storage.
