Does the same user exist on the remote system, with the same uid, etc.?

If you're using rsync with ssh as the transport, and connecting to the
remote machine as the backups user, that's who will own the files on
its local filesystem...

You've written a lot of narrative, but show us precisely what commands
you're running.  Why would you run the command as root, and ssh as
backups, when you want them to be owned by "normal" ?

You can run the command as root, and use restricted ssh keys (use
authorized_keys to restrict it to executing a specific rsync
command)....  you can run rsync as a regular user to that user's
account on the remote system...
