[Veritas-bu] bpduplicate using the -id switch

Sorry Ryan, yes I know your name, I was talking to the Br[i|y]an's who
developed and maintain bpVault.

I guess that was a bit confusing, huh?

Thank Ryan.

I should've looked at David's script more. The -i option to bpduplicate
was new to me previous to this. I don't have any opinion on what way its
faster to duplicate by (client, class, etc.), only that duplicating by
media would be more difficult to script, which David has done. The logic
for David's script is more advanced than mine (nbduplicate). I wasn't
able to figure out how to do more than one duplication at a time with it
though (though there's probably a way to do so), so I've not moved to
it.

BTW, my name is Ryan, not Br[i|y]an ;-)

My workaround has been to make backups go into different pools, then
duplicated based on those pools in separate streams. I still duplicate
_into_ the same pool though.

Hope this helps.
