EBS Snapshot billing

Question

Hi, I have an EBS volume of 1 TB size however the data utilization is less around 120 GB.

Since the firs EBS snapshot is for full volume that's 1 TB. Will I be billed for full EBS volume snapshots that's 1 TB or will it be only 120 GB?

Answer

Thanks for the clear description. In your case, 120 GB will be billed.

Check https://aws.amazon.com/ebs/pricing/ and https://aws.amazon.com/premiumsupport/knowledge-center/ebs-snapshot-billing/ for more information.

Example 7 – EBS Snapshots

Snapshot storage is based on the amount of space your data consumes in Amazon Simple Storage Service (Amazon S3). Because Amazon EBS does not save empty blocks, it is likely that the snapshot size will be considerably less than your volume size.

Answer

EBS snapshots costs are based on the amount of space your data consumes (empty disk blocks aren’t counted). Snapshots are incremental by nature, and costs will be related to the amount of data that changed between snapshots.
Let’s say your EBS volume size is 1TB and it is consistently using 10 GBs of space, and every day there’s 1GB of data changed from the previous day. You have daily backups of the volume happening and the backups are kept for a month.

The initial snapshot cost will be $0.05 x 10(GBs) = $0.50.
The rest of the snapshot will cost $0.05 x 1 GB x 29 (snapshots) = $1.45.
