<p class="MsoNormal">If your primary concern is interoperability and portability I would look at mbtiles or geopackage. Both cache types store the tiles in a single file which could be used in a few platforms and easily backed up. The only issue with these
caches (sqlite) it a tendency to lock up during heavy concurrent writes, mapproxy has implemented bulk writing to help address this issue for mbtiles (not sure about geopackage). If your users are using a fully seeded cache this won't be a big issue.<o:p></o:p></p>
