Are you writing about the system backup?
The system backup was based on someone copying over "sysbk" from an open source repository. I don't think anyone's looked into modifications of the core code as of yet.
It's definitely doable, and will be in our commercial backup package, but there's no date set yet.
In the meantime, if you'd like to modify the sysbk code so it works, I'm sure JBMC Software will be happy to consider adding it to the official release.
