The [Proxmox Backup Server](https://www.proxmox.com/en/products/proxmox-backup-server/overview) (PBS) facilitates the backup and restoration of virtual machines (VMs) running on the Proxmox Virtual Environment. Version 4.0 of PBS introduced support for storing backups in S3-compatible cloud storage providers such as Wasabi Hot Cloud Storage. This article details the process to configure PBS to store backups in Wasabi. > [!NOTE] > The data restoration process is handled by your specific backup software application. As there are many potential variables that will affect your unique environment, Wasabi strongly recommends that you seek the guidance of your backup software's technical support team in the event that you encounter difficulty or have application-specific inquiries. ## **Prerequisites** - Active Wasabi Storage account. - Wasabi bucket created and the access and secret keys available. Do not enable Versioning or Object Lock since PBS does not support them. - Proxmox Backup Server version 4.0 or higher. This solution was tested with version 4.0.11. - Virtual machines to be backed up added to the Proxmox Virtual Environment (PVE). PVE version 8.3.0 was used during this testing. ## **Configuring Proxmox Backup Server** In Proxmox Backup Server (PBS) version 4.0 and higher, PBS can backup virtual machines hosted on Proxmox Virtual Environment to Wasabi Hot Cloud object storage. You will need to have already created a Wasabi bucket without Versioning or Object Lock to be used for these backups. See [Creating a Bucket](https://docs.wasabi.com/docs/creating-a-bucket) for details. You will also need the Access key and the Secret key to access the Wasabi bucket. Details about Access and Secret keys can be found in [Creating a New Access Key](https://docs.wasabi.com/docs/creating-a-new-access-key). Follow the steps below to configure the PBS. 1. Login to your Proxmox Backup Server. Expand the **Configuration** menu, click **S3 Endpoints**, and click **Add**. ![](https://cdn.document360.io/bef0a1ea-7768-4d5a-b520-c4fe2f7fafad/Images/Documentation/Screenshot_2025-12-17_at_10_02_00 AM(1).png) 2. Give your endpoint a name such as “Wasabi”, enter the Wasabi domain name for the region your bucket is in, your region, your Wasabi Access Key, and your Wasabi Secret Key. Click **Add**. > [!NOTE] > This configuration example discusses the use of Wasabi's us-east-1 storage region. Use the region your bucket is located in. For a list of domain names for each region, see [Service URLs for Wasabi's Storage Regions](https://docs.wasabi.com/docs/service-urls-for-wasabis-storage-regions). ![](https://cdn.document360.io/bef0a1ea-7768-4d5a-b520-c4fe2f7fafad/Images/Documentation/Screenshot_2025-12-17_at_10_05_03 AM.png) 3. You will now see Wasabi as an S3 Endpoint in PBS. ![](https://cdn.document360.io/bef0a1ea-7768-4d5a-b520-c4fe2f7fafad/Images/Documentation/Screenshot 2025-12-17 at 10.05.31 AM.png) 4. If a non-root user does not exist on your PBS server, add a PBS user by clicking **Access Control**, then **User Management**, then **Add**. ![](https://cdn.document360.io/bef0a1ea-7768-4d5a-b520-c4fe2f7fafad/Images/Documentation/Screenshot_2025-12-17_at_10_18_24 AM.png) 5. Enter a username for the new user, select the appropriate realm for your environment, and enter the user’s password twice. Optionally enter a first and last name and email address. Click **Add**. ![](https://cdn.document360.io/bef0a1ea-7768-4d5a-b520-c4fe2f7fafad/Images/Documentation/Screenshot_2025-12-17_at_10_19_45 AM.png) 6.
