Amazon Backup pricing

With Amazon Backup, you pay only for the amount of backup storage you use and the amount of backup data you restore in the month. There is no minimum fee and there are no set-up charges.

Amazon Backup storage

Amazon Backup storage pricing is based on the amount of storage space your backup data consumes. For the first backup of an Amazon Web Services resource, a full copy of your data is saved. For each incremental backup, only the changed part of your Amazon Web Services resource is saved.*

The storage amount billed in a month is based on the average storage space used throughout the month. Your storage usage is measured in GB-Month, which are added up at the end of the month to generate your monthly charges.

The restore amount billed in a month is based on the amount of data restored for the month. The data restored in a month is measured in GB, and represents the sum of the data across all the restores performed in the month.

Example 1:

Assume your Amazon EFS backups are stored in the China (Beijing) Region. You use 400 GB of Amazon EFS backup storage during 15 days in April and 800 GB for the other 15 days in April. At the end of April, you would have the following backup storage usage, in GB-Days:

Total usage (GB-Days) = [400 GB x 15 days] + [800 GB x 15 days] = 18,000 GB-Days

We add up GB-Days and convert to GB-Month by diving by 30:

Total GB-Month = 18,000 GB-Days/30 = 600 GB-Month

Total Monthly Storage Charge = 600 GB-Month x ¥0.348 = ¥208.8

Let’s also assume that you restored 10 backups that were 1GB each. At the end of April, you would have the following backup restore usage, in GB:

Total usage 10 restores x 1 GB = 10 GB

Total Monthly Restore Charge = 10 GB x ¥0.139 = ¥1.39

Adding both your backup storage and backup restore charges together gives you your total monthly Amazon Backup bill:

Total Monthly Amazon Backup Bill = ¥208.8 + ¥1.39 = ¥210.19

*This applies to all backup storage except for on-demand DynamoDB table backups and Amazon Aurora cluster backups, which create full backups.

Example 2: Amazon Backup for S3

Assume you have 500 TB of Amazon S3 data stored in the China (Ningxia) Region. Let us also assume that your S3 buckets has 100 million objects of 5 MB each. You want to create a backup copy of the S3 bucket using Amazon Backup. Your monthly TCO will be calculated as follows:

Total monthly storage charge ¥0.438 per GB-Month = 500,000 x ¥0.438 = ¥219,000.

S3 GET APIs charges ¥0.0135 per 10,000 requests. Assuming 8 GET APIs per new object, total GET API charges = (¥0.0135/10,000)*8*100 million = ¥1080. 

S3 LIST API charges ¥0.00405 per 1,000 requests. Assuming 1 List per 500 object, max possible LIST API charges = (¥0.00405/1,000)*(100 million/500) = ¥0.81. 

Assuming 20 million EventBridge events across all objects in the 500 TB bucket for the initial backup. EventBridge matched events charge ¥6.75 per 1 million events. Maximum possible EventBridge charge on your S3 bucket = (¥6.75/1 million) x 20 million = ¥135

Total monthly TCO for your first full backup = ¥219,000 + ¥1080 + ¥0.81 + ¥135 = ¥220,215.81

Let us also assume that you decide to restore 2.5 TB of your backups.

Total charge of restore = 2,500 x ¥0.1752 = ¥438

S3 PUT API charges ¥0.00405 per 1,000 requests. Assuming 1 Put per object, max possible PUT API charges = (¥0.00405/1,000)*5 million = ¥20.25.

Your total TCO = ¥220,215.81+ ¥438 + ¥20.25 = ¥220,674.06

Your monthly bill for Amazon Backup = ¥219,000 (backup storage in Ningxia region) + ¥438 (restore) = ¥219,438

Your monthly bill for Amazon S3 = ¥1101.06 (GET requests = ¥1080, LIST requests = ¥0.81, PUT requests = ¥20.25)

Your monthly bill for Amazon EventBridge = ¥135

Please note that there will be additional charges for S3 Versioning. Incremental backups will incur additional charges for storage as well as for S3 GET/LIST requests and Eventbridge.
