The first thing you need to understand is that for the EMC Symmetrix,
where the BCVs are usually found, the Symmetrix is simply a disk
controller.  A very good, expensive one, but basically just a disk
controller.  As such, you can't expect to back up a BCV volume without
making it available to a host somewhere first.  So, yes, you do need to
mount the volume.  We do it here for our Oracle backups.

Mounting that disk gets a bit tricky since it's an identical
block-for-block copy of the original.  File systems like the Veritas
file system will not let you mount the split BCV copy on the same
server.  I don't know about HP-UX's file system.  We mount them on a
special backup server which is also a media server (Solaris, not HPUX).

Netbackup does offer an encryption component although I've never used
it.  A quick google search for "netbackup encryption" came up with a few
links to Veritas pages, including
