enclosed some cloning principles we use:

1st: we backup to multiple pools
   (i.e. Oracle to OraclePool, Notes to NotesPool, other to Default)
2nd: we clone all the backups to ONE clonepool
   reason: we have to move not that much cartridges!
   (the so called "volume cloning" is no help here,
     one input tape --> one (ore two :-) output tapes)
3rd: we send cloning volumes offline (!near)
    reasons: - it gives me a much better feeling to RECOVER
             from verified tapes instead of sending them
             offline for "disaster recovery"
             (it's quite possible they never get used) but ... :-(
             - there had been (?) an issue, that NetWorker
             accepted the clone saveset ONLY, if the original
             had been marked "suspect"
             (but this seems to be gone away, if I understand this thread
              correctly)
4th: we only return cartridges which have been already recycled
      (i.e. mminfo -q volrecycle -q !near -r volume)

But one question seems to be still open:
Does cloning some kind of de-multiplexing or not?
