i understand. i hoped tarsnap knew what blocks (do not) get reused. it's unfortunate, because some backups happen to just lie around for very long. it would be nice to take advantage of (the low cost of) glacier for that. that said, if it's not possible with tarsnap now, it's not possible now. :D. if you find a satisfying possibility to incorporate it in the new backend(s) design (if that's fixable in the backend(s) alone), i'd surely be pleased.
