Why do I receive error message "the selected object storage does not support S3 Object Lock feature" in Veeam?

When setting the Wasabi Veeam Object Lock Integration, you may encounter the error "the selected object storage does not support S3 Object Lock feature" when trying to set immutability inside Veeam Backup & Replication. This is an indication that Veeam was unable to validate Object Lock information about your bucket.

Here is a list of things you can do in order to verify your setup is correct on Wasabi:

  • Make sure that you have selected a bucket with the Object Lock feature enabled.
  • Check that the Object Locking setting looks like the image below. It is not necessary to configure this, since Veeam Backup & Replication will automatically use Compliance object lock mode for each uploaded object.


  • Veeam Backup & Replication uses an API call that will return information about the Object Lock setting in your bucket. There are three types of responses: 
    • 200 - with the Object Lock configuration.
    • 404 - Object Lock configuration not found => Bucket isn't an Object Lock bucket.
    • 403 - Access denied => this will get translated into Veeam as Bucket with no Object Lock.
    Check that the sub-user, whose Access and Secret keys you set in Veeam, has permission to retrieve the Object Lock information about the bucket. The policy suggested by Veeam can be found here
