export page or project from joomla website

Hi,
I see that export page from joomla website is impossible, but this is a great problem because if

i begin desktop and continue to modify online i have two project not sincronized
and
if i have the site online, i cannot move to other website or reset the site in case of problem or fault.
the only way is to loose the work project.

please, this is a very important function.

thank you
