No, I don't think end users care the smallest jot about what format their data gets exported in for backup, just so long as they can re-import it (otherwise it's not really a backup, is it?) The only time I can think of that they might care or have an awareness that formats matter is if said data is being transported between different applications where there is some pre-existing standard (e.g. BeerXML in the world of brewing caculators.) Aside from that you've conflated two unrelated requirements.
