Source and Destination

Hi there

I am feeling a bit dim and wonder if I have understood the principle of Touch correctly ?

As I understand it I must run Touch on the SOURCE device i.e. the device which contains the file I want to back up - like my Laptop Computer ?

I then install Syncback on the computer that contains the Back Up Drive onto which I wish to backup the files that are on my laptop ?

BUT when I try that installation, create a profile, Open Expert Mode, Select Touch the screen says "Destination Files are on the Touch Device" but I want it to say "Source File...."

Am I missing something / how do I configure touch to backup my laptop onto the external hard drive connected to my desktop computer ?

Many Thanks
