My comments for the above paragraph: Yes, a lot of decisions in Bacula and elsewhere are tradeoffs. In the case of the IBM lin_tape driver, I am sure that what you write about it being better is correct. However there needs to be a technical person familiar with Bacula to implement it, and that person needs access to such a tape setup (probably onsite). I am past the time when I am available to develop major new "tricky" technology, so this would leave either a community submission, or Bacula Systems to implement it. It is quite possible that Bacula Systems would implement this feature if it turns out to be something that a number (3 or more) of important customers want -- i.e. it is mainly a cost/benefit question for them.
