Today there is no such exit code, feel free to add a feature request at
https://sourceforge.net/p/dar/feature-requests/

For a live filesystem such condition should be very unfrequent, and
second, the storage gain not saving a differential backup that has no
file saved in it is very little: its usually a matter of a few tens or
hundreds of kilobytes depending of the number of files in the backup scope.
