Configuring Veeam Backup with Züs S3 (ZS3)

Züs offers decentralized, S3-compatible object storage via ZS3Server, which can be integrated seamlessly with enterprise backup tools like Veeam Backup for Microsoft 365.

This guide will walk you through the full process of connecting Veeam to Züs S3 for storing your backups securely on decentralized cloud infrastructure.

1. Launch Veeam and Navigate to Backup Infrastructure

In the Veeam Backup & Replication console, go to Backup Infrastructure → Backup Repositories → Add Repository → Object Storage. This opens the object storage integration wizard.

Select "S3 Compatible" as Storage Type. Veeam supports multiple cloud object storage providers. Click next.

2. Enter Züs S3 Endpoint & Region

In the “S3 compatible storage system” section, fill out the fields:

• Service Point: https://YOURID.gslb.z3.zeroservices.eu (Replace YOURID with your ZS3 instance ID or deployment name)

• Data Center Region: eu-central-1 or us-east-1 (Choose based on your configuration — this does not impact functionality)

3. Add S3 Access & Secret Key

Click on the “Add” button beside the account credentials dropdown:

• Access Key: Your ZS3 Access Key

• Secret Key: Your ZS3 Secret Key

• Description: (Optional) Label your key for clarity

Click OK, then select the added credential from the dropdown and then click on Next.

4. Select the Bucket & Folder

In the “S3 compatible storage system bucket” screen:

• Bucket: Choose your designated bucket (e.g., Veeam)

• Folder: Optionally create or select a folder like Backup365 to organize backup data.

You can also check the immutability option to prevent deletion or tampering during the retention period — a best practice against ransomware attacks.

5. Finalize Configuration

Enter a name and description for your object storage entry.

Example:

• Name: zs3-zero-backup

• Description: Created by zero at 05/10/2024 19:07:10

Click Next and finish the process.

Your Züs S3 storage will now appear under: Backup Infrastructure → Object Storage

6. Review Cloud Credentials (Credential Manager)

After clicking Next, Veeam opens the Cloud Credential Manager automatically to display the credentials you just created.

Here’s what you can do in this view:

• Review the created S3-compatible credential.

• Edit the credential by selecting the entry and clicking the Edit button.

• View or modify the:

  • Access Key

  • Secret Key

  • Description (e.g., created by your team or timestamped info)

This is useful for quickly verifying that the correct keys were used, or updating them later if rotated.
