Backintime KDE as root with ssh / key based login w/o password

Hi,

thank you for this great tool! I'm used to use backintime with ssh and key based authorization, with no password set on the key.

This does work still for a non-root account, but for a root account it does not work as the setup tries to save the password.

However, with an empty password there is no need to save, nor to cache etc. a password.

What I would recommend is to add a check-box 'key with no password' or just don't try to save when the password string is empty.

The reason I set up systems this way and not as a user account is that at the moment I set up the system there is no other user then root, the owner of the system set up his own account.

Having backintime backing up /home it will automatically catch the user account plus is able to save /etc, /boot, /var/log - which enables me to help in case something happens.

Any ideas how to get this running as root the described way? Or do I have to change the code?

greetings kai
