Archive iOS back-up on Windows

I want to archive my iOS back-up I made in iTunes. But it seems, in contradiction to macOS, impossible to do that on Windows. When I press my right mousebutton there doens't open a tap where I can click 'Archive'. On the picture you can see the situation and I'm trying to open that unexistable tab to press 'Archive'.

How can I archive my iOS back-up I made in iTunes on Windows?
