Object Storage

Our S3-compatible Object Storage provides you with storage capacity for saving data in "Buckets". Any data you save in your Bucket is saved in a Ceph cluster. If you set the visibility of your Bucket to public, everyone can access the Bucket to view or download files via a URL that follows this format:

https://<bucket-name>.<location>.your-objectstorage.com/<file-name>

Object Storage is mainly used to store and share data as it is not possible to edit any data that you uploaded to a Bucket (objects are immutable). So the main purpose of Object Storage is "WORM", which is short for, "Write once, read many [times]". Here are some example use cases:

  • Save (automatic) backups
  • Share data via a public URL

Buckets are a stand-alone product that you can use independently of any other cloud resources. Via Cloud Console, you can complete basic tasks such as creating a Bucket or generating credentials. For all other features and functionalities, you need to use our S3-compatible API. Here's how you can use our API:

  • Amazon S3 compatible tools recommended
  • Amazon S3 API with the Hetzner S3 endpoint

In the article "List of supported actions", you can check which S3 features our Object Storage currently supports.

Pricing

Object Storage uses a pay-as-you-go billing model based on your total account usage.

The base price is billed per hour with a monthly price cap, regardless of how many Buckets you have. It includes a free quota of storage and traffic that accumulates with each hour of Object Storage usage. By the end of the month, your total usage is subtracted from the total free quota that was accumulated throughout the month.

Unused free quota expires at the end of each month and cannot be carried over to the next month.

Storage and traffic that exceed the free quota included in the base price are billed separately.

For more information about the prices, see hetzner.com/storage/object-storage.

The following is free of charge:

  • Ingress traffic
  • Internal traffic within the network zone eu-central
  • S3 API calls such as PUT, GET, or DELETE

Base price

You are charged for every hour you have at least one Bucket, even if it's empty. At the end of the month, the storage and traffic consumption of all Buckets across all projects are combined and billed as one.

In the following example, Object Storage is used during the hours of 3 p.m., 4 p.m., 5 p.m., 6 p.m., and 7 p.m., meaning there was at least one Bucket in use during each of these hours. Therefore, you will be charged for a total of five full hours.

Free Quota

As months vary in the number of days and therefore the number of hours, the maximum free quota depends on the month.

Seasonal time changes are not taken into account

Total storage per account Total traffic per account
Month with 31 days max. 744 TB-hour max. 1.1160 TB
Month with 30 days max. 720 TB-hour max. 1.0800 TB
Month with 29 days max. 696 TB-hour max. 1.0440 TB
Month with 28 days max. 672 TB-hour max. 1.0080 TB

In the example below, three Buckets (blue, pink, green) were used. These are the only Buckets that were created during the entire month. At the end of the month, the usage is charged like this:

  • In total, Object Storage was used for three hours. This accumulates to a total free quota of 3 TB-hours of storage and 0.0045 TB of traffic.
  • Within those three hours, the entire 0.0045 TB of traffic and only 2.3 TB-hours of storage were used. This means that 0.7 TB-hours of the free storage quota were not used. Those are now expired.
  • Since the usage was within the included quota, no additional costs are charged.
Example

4 p.m. 5 p.m. 6 p.m. 7 p.m.
Storage: 0.3 TB-hour
Traffic: 0.0010 TB		 Storage: 1.5 TB-hour
Traffic: 0.0010 TB		 Storage: 0.3 TB-hour
Traffic: 0.0025 TB
Storage: 0.2 TB-hour
Traffic: 0 TB

Prices for usage in excess of the free quota

We will bill you for the excess storage and traffic in increments of 100 MB ( = 0.0001 TB). If you don't use the full 1TB, you will be charged less.

The price for additional storage is calculated like this:

(net price * TB-hours) + VAT

Minimum billable object size

Minimum:

  • 64 kB

The minimum billable object size is the size that you will be charged for, even if the data actually stored is smaller.

Objects that are smaller than this minimum size are charged as if they had this size.
