Hi Peter, That error message "you're trying to backup an encrypted disc to a non encrypted disc" means that your 'Mac's hard drive is using FileVault encryption to secure your data, but the hard drive you're using for Time Machine is not encrypted.' Automatic login is disabled if your have FileVault enabled: In System Preferences > Users & Groups > Login Options after enabling FileVault, you’ll see that Automatic Login is set to Off and dimmed—you can’t enable it. And, in System Preferences > Security & Privacy > General, the checkbox labeled “Disable automatic login” disappears completely when you turn on FileVault. This means you’ll always have to supply your password when you turn on your Mac, restart, or log in.
