I did ssh-keygen with an empty passphrase, specifically so that I 
could place the public key on a target machine (the one with a DAT 
backup drive) then set up something like

sudo <ordinary user> scp ~/my/backup/files <ordinary 
user>@targetmachine:~/my/backup/copy/

as part of a script which is run as a cron job in the middle of the night.
