Thank you guys so much.
I think I can figure this out. 
I discussed with a veteran sys 
admin and he is coming to the same conclusions 
about the keys and the process being offered to me here.
I have one Windows server remaining to add via Samba.
At least I'm not getting the 'unable to read 4 bytes' error with this one.

yes, but, as you can see, the transfer was done with a different remote user.
Presumably, root cannot login with password authentication. Of course, root 
will need to be able to login with public key authentication for backups to 
work.
