I get the error message `Unable to mount host` when I try to connect to a SFTP/SSH site as backup destination as superuser (root). What's wrong?

A:
Probably your remote destination is not yet added as trusted machine for user 'root'. Nautilus asks regular users when connecting to servers for the first time whether to trust the remote machine or not. Though this confirmation is valid only for a certain user. To connect remotely as superuser/root you'll have to add the remote machine to root's trust pool.

In order to do so, open a terminal and type the following: sudo ssh <username>@hostname

You'll be asked whether you trust the remote machine or not - answer with yes. You should now be able to connect to the remote destination from within the Simple Backup configuration GUI.
