I don't like these staged backup for these reasons. Every step (e.g. NAS backup to Hetzner) can cause an error, so adding steps increases the probability of error. Personally, I just back up directly from my machines to a local storage server and to a cloud object storage with object lock (so that e.g. ransomware encryption or attempts to remove the data do not work).
