Configure Object Storage as a Backup Target
By default, backup data gets stored on the storage provided by the Backup Service. You can add Object Storage endpoints to the list of storage locations. Consider this option when you want to use further features from the respective Object Storage or ensure that the distance between the location of the backup data source and backup data target is of a certain near or far distance.
Backup on Object Storage for Free: From August 1, 2025, to September 30, 2025, IONOS is charging no handling fee on backup data stored on Object Storage. The Advanced Backup Pack as well as the Object Storage fee of your service provider still apply.
Object Storage setups must be configured per individual backup unit.
Open the Backup Console
1. In the DCD, go to Menu > Storage & Backup > Backup Unit Manager.
2. Select the required backup unit and click Open Console.

Configure a new Backup Storage
By default, the storage of the backup service is pre-selected as the target storage for backup data. Follow the instructions to add your Object Storage:
Navigate to Backup Storage in the left navigation of the Backup Service Console. The list of locations will be displayed.

To add a location, click on Add Location in the actions menu on the right panel. A fly-out configuration menu will be displayed.
Select Public Cloud.

Note: The green arrow next to the configuration item indicates that this configuration option will incur additional costs to your backup plan. Backups on Object Storage require the Advanced Backup Pack, which is applied per device. Depending on the price list of the Object Storage service provider, Object Storage may create additional costs.
The configuration of the endpoint does not activate additional costs. Any cost becomes applicable only once the new storage location is configured in a backup plan and applied to an instance.
The service fee will differ when using the IONOS Cloud Backup Service in combination with the Object Storage, as it does not use the backup storage. Refer to the price list for the applicable prices for the backup service fee and the Advanced Backup Pack.
Depending on your contract region, you can select IONOS Object Storage from the drop-down list. Alternatively, you can select other pre-configured Object Storage options or select S3 compatible, which allows manual configuration of S3 Object Storage compatible endpoints.
When you select a third-party Object Storage from the drop-down list, please follow their instructions to add or connect your account to the Acronis backup unit.
When you select S3 compatible as your target, click on Connect to continue the configuration.
Enter the Object Storage endpoint URL and the Access Key and Secret Key belonging to a user who is a member of the Object Storage installation. Choose the authentication protocol supported by your Object Storage service provider. IONOS supports the latest authentication protocol, AuthV4.

Click Connect. The Backup Service will verify your settings. After successful verification, you will be requested to specify the target bucket that will receive the backup data. The drop-down list will show all buckets that are available to the user, represented by the previously given Access Key.

After the configuration is completed, you need to confirm the setup by clicking Add. The screen returns to the overview of backup storage locations, which will contain the newly added Object Storage location.

Result: The backup unit is prepared to use Object Storage as a backup storage target within backup plans.
Configure a Backup Plan to use Object Storage as backup target
Navigate to Management in the left navigation of the Backup Service Console.

Select Protection Plans from the list of options. You will see all existing protection plans within this Backup Unit.
To create a new backup plan, select Create Plan from the actions menu on the right panel.
A default configuration of a backup plan will be opened that contains several categories. Ensure the category Backup is enabled by setting the slider to the right. If the category Backup is not expanded then click on the category to unfold the configuration details.

Navigate to the configuration element Where to backup. The default backup storage is displayed. Click on Cloud Storage to open a list of available backup storage targets. Select the Object Storage location you have configured.

The backup storage location configurator closes automatically and shows the configuration page of your backup plan again. Depending on your previous settings, the pack Advanced Backup Pack gets activated, which is required for storing data on an Object Storage.

Continue to configure further details of your backup plan, for example schedule, increments, encryption, or additional advanced features.
Once you have completed your setup, click on Create to apply the configuration plan.
You can add the backup plan to your device.
Result: The backup plan is configured to use Object Storage as a backup target.
