Please note, that you need to connect to your remote destination from commandline when using ssh/sftp in order to add the remote machine to your list of known and trusted hosts. You can do so in terminal:
ssh user@host
sudo ssh@host (if you want to connect as root, e.g. from scheduled backups).
Then confirm identity of the remote machine. After that, ssh and sftp should work.
Ok, thanks for checking.
