Dwight,

Thanks for the thoughts, very helpful!

Would you use bcopy separate from bacula, creating your own scripts
that run off a cron job?  Or would you somehow integrate using bcopy
into a bacula job using custom bacula scripts?

Also, do you know if bacula-sd has to be shut down to release the tape
drive for bcopy to use?  I haven't experimented yet, so I don't know.
But if you have, what have you discovered?

Thanks for the suggestion.  I'm actually already doing that as well.
All my full backups are stored as Full_*.

I guess I was hoping that there was a bacula feature that does a
volume copy.  It sounds like that isn't the case if you are also
considering using bcopy.  Too bad, maybe it could be a feature for a
new version.
