First response: there isn’t any particular reason, just to be up to date (Periodically I update all my software to the last version available and these days is the turn of duplicacy).
Second response: it crashes because it lacks a function from a system library:

Anyway, I presume it’s better to stay on 2.7.2 as long as I share the storage between the two hosts.
