Responsive background images

When using a background image by CSS. How do you get the image to contain itself within smaller screen sizes and then when re-sizing stays proportional to its screen size. Is there a pixel by pixel ratio to save the image at? Do you use different image sizes of the same image and create media queries? Maybe some Javascript?

For this, I usually just use "background-size: cover;", but apply it to each of my breakpoints. This way it inherits the width of the screen resolution that you're working with.
