Well we want to run it against the snapshot so I think we need the -S option. When you run it against the FS filtering by SNAP_ID, you miss any files that have been deleted since the snapshot.

I have also played with the -A and -a parameters with no combination that I can find making it any better. Thanks for the feedback.
