Veeam Backup Error : Invalid Credentials for S3 Endpoint

I hit this the error whilst adding a S3 Storage repository on Veeam Backup (version 10) – ” Invalid credentials for Amaazon S3 Endpoint.See logs for details” . The credentials we correct and verified using AWS CLI .

The cause is *not* a credentials issue but a permissions requirement by Veeam.

I found the IAM policy to below on AWS fixes the error. I think this can be improved and works for now. The error message could do with a bit of improvement though.

        }
    ]
