Because, at least for tapes, this practically brake hardware compression; so
if i enable software encryption i need also to enable software compression,
and this add some more slowdown.

I've done some tests in my production environment in this weeks, so real
data, and:

 + software encryption add 5-20% to backup time
 + software encryption add 10-25% to backup space
 + software compression not tested
 + media-based, not client-based; it is a pros-and-coons thinks, i know, but
   seems to me a beter approach.

hardware encryption (and compression) is really and totally transparent to
backup, eg a backup done with hardware encryption enabled take same time and
space of an hardware encryption disabled backup.


For RDX there's no hardware compression, so software encryption effectively
could be a decent approach; but seems supported also there, so i'll give it a
try...
