It looks like Allen has had a better experience, but in my recent
experience with ProtecTIER, 2 logical libraries with NetBackup & TSM
feeding in the "same data" (we were migrating to TSM) the data WAS
"different" and dedupe ratios dropped like a stone.

As for using it as a  justification to migrate eveything to TSM, it is
obviously true, but in my opinion a weak argument.  It could easily be
remedied by throwing in some more disk.  You should focus on the management
costs of running multiple environments.  e.g. do you have an automated
backup check that generates problem tickets for backup failures?  just TSM
= one ticket interface.  The list goes on.
