Seems like it might make sense to consider using a better format for
these files and also to allow us to more easily add things in the future
(ending LSN, ending time, etc) for backup tools to be able to leverage.
Perhaps we should change this to having just a single file returned,
instead of two, and use JSON for it, as a more general and extensible
format that we've already got code to work with..?

Thanks,

Stephen
