After reading, both links you provided won't work on 2019, so the only way of backing up is manual. You have to remember that you're dealing with a totally different version of Windows, there are things in here we don't even know about until you read about it. I don't mind a manual backup, keeps me on my toes. I would guess eventually they will come up with something, they always do. In the meantime, just have to keep chugging along.
