- MinIO object storage set up per <https://docs.min.io/community/minio-object-store/index.html>
- Veeam requires TLS connections to the object storage.  This can be configured per <https://docs.min.io/community/minio-object-store/operations/network-encryption.html>
- The S3 bucket, Access Key and Secret Key have to be created before and outside of Veeam.
