ReadyDR - backup home directory shares?

The "ReadyDR" FAQ's seem to skip over any mention on if it's supported for backing up "home" shares.  On my own OS 6.6 devices, however, I don't seem to have that option (though I do have snapshots working on those home shares.)

Is ReadyDR supported for home shares?  If so, how can I enable it? (or perhaps I'm experiencing a bug related to active directory shares.. again?)  

(readynas 516, OS 6.6.0, On an active directory domain, snapshots enabled for the home shares, and backing up the "Home Folders" works fine with an old-style rsync job.)

Thanks

Gary
