I want to backup some site and pages, and reuse the data including;

images
titles
catergories
author
http image address and all the 
body text

ALL together and then be able to edit the body text and reuse it in other
sites,

Is there a simple solution to doing this ?
here is an example of the pages

Thanks you in advance for your time.
