Am i not able to save a cloud with a background as a SVG file?

I have a cloud which is red and white text on a black background. when I save as a SVG file and open in Inkscape to resize the background is gone (its white again). I can save with a black background to PNG but I want to save as SVG so I can continue to resize in Inkscape without distortion. Help?!

Could you please try EPS?
For SVG many image editors ignores background settings.
