your earlier patch seemed like a good start. maybe you push that for a start for Kenneth to merge and come up with a more detailed solution later?

pathlib seems to be new in python 3.4 . seeing that for the foreseeable
we should run w/ older pythons incl. 2.7's you should look for
alternatives. i don't see a reason why plain python filesystem support
shouldn't support for our basic needs. failing to permissions or such
can be easily made reported but no failing point.

there was a windows port branch once that never made it into mainline
 https://code.launchpad.net/~kevinoid/duplicity/windows-port
maybe you can draw some ideas from that?
