Comment 2 for bug 946544

As an upstream developer, I'm not sure that writing metadata by default agrees with the Shotwell design philosophy, which is to be completely non-destructive and not touch users' photo files unless specifically requested. That said, I think this problem is real and would be well-served by adding a photo backup feature to shotwell. We have an upstream request for such a feature here: http://redmine.yorba.org/issues/1963
