The --best one is doing the index files, not the data stream.

This comes up here about once a month :-).  There was a lengthy discussion
last November.  Quoting Alexandre Oliva:

  ... people who tried to use bzip2 for backup compression ended
  up finding out it was just too slow.

And then Jonathan F. Dill after some (non-Amanda) timing tests:

  In summary, bzip2 gave me 3.84% more compression at a cost of a more
  than fourfold increase in the time that it took to run the compression.

Even so, there is something called the "FILTER API" that should allow
arbritrary programs to be inserted in the data stream (compression,
encryption, random number :-) and this would be the logical place to
put this effort.
