Great question! I've wondered about a similar thing - both from the perspective of DR, and also from the perspective of simply having clearer tracking of configuration and changes made over time.
We regularly run "li export-studio-plugin" using the Lithium SDK to export all Studio plugin files, and keep a copy of the latest set of files in a Git repository.
I'd love to also have a script that automated extracting custom content settings (and/or other settings) so we could keep a better track of them too. If anybody has something like that, please share!
