I want to know how I'm billed for Amazon Elastic Block Store (Amazon EBS) snapshots.
Charges for Amazon EBS snapshots are calculated by the gigabyte-month. That is, you are billed for how large the snapshot is and how long you keep the snapshot.
Pricing varies depending on the storage tier. For the Standard tier, you're billed only for changed blocks that are stored. For the Archive tier, you're billed for all snapshot blocks that are stored. You're also billed for retrieving snapshots from the Archive tier.
The following are example scenarios for each storage tier:
- Standard tier: You have a volume that's storing 100 GB of data. You're billed for the full 100 GB of data for the first snapshot (snap A). At the time of the next snapshot (snap B), you have 105 GB of data. You're then billed for only the additional 5 GB of storage for incremental snap B.
- Archive tier: You archive snap B. The snapshot is then moved to the Archive tier, and you're billed for the full 105-GB snapshot block.
For detailed pricing information, see Amazon EBS pricing.
To view the charges for your EBS snapshots, follow these steps:
- Open the AWS Billing Dashboard.
- In the navigation pane, choose Bills.
- In the Details section, expand Elastic Compute Cloud.
You can also use cost allocation tags to track and manage your snapshot costs.
Why did my storage costs not reduce after I deleted a snapshot of my EBS volume and then deleted the volume itself?
Why am I being charged for Amazon EBS when all my instances are stopped?
