In this mail, it really sounds like you're using your DD as both primary storage and for TSM storage.
I am, right now, using the DD as a target for direct-written database backups, only. So that's not really "primary storage", as I think about it.
If the DD box fails, what are your losses?
If someone puts a high-caliber bullet through my Gainesville DD, then I recover it from the replicated offsite DD, perhaps selecting a snapshot. If someone puts a high-caliber bullet through both of them, then I have lost my backups of a bunch of important databases.
Sorry for all the questions, I'm just trying to get an idea how you're using this box.
No problem. Our conversation is fuzzed by the fact that I am also talking about how one _might_ use it for TSM storage. I'm contemplating it, but not doing it at the moment.

In my planning, the DD gets copied / offsited to a remote DD, so that's the somewhere else. - Allen S. Rout
