Oracle has a bunch of high-tech whiz-bang recovery and analysis tools

When TSM is duplicating your data (aka backing
up storage pools), there is no logical connection between your
primary storage pool and your copypool.
Well . . .yes . .. no . . .
All our eggs are in one basket no matter what. The logical connection
between pri and copy pools is TSM itself. A

The elephants in the room:
It is tempting, once DD gets in the door, to move all database
backups (the typical TDP/RMAN and SQLLiteSpeed stuff) to go directly
to DD. (No TSM involved, so save money on licenses?)
So the data is both deduplicated and compressed before you
send it offsite?
Yes, that is how the DD handles replication.
DD is a inline dedup system. When data come into the DD
it is deduped, what is left is compressed, then it
is written to disk. Only the new unique data is replicated.
A while back I did some searching in to NFS file pool for LanFree storge
agents. I figured that since Sanergy was using NFS for setup but sending
data across FC, that TSM should have to support NFS directly. I found a
comment in the TSM manuals (v5.5) that IBM does not support NFS for
LanFree
and it does limit the available mount points
One of the real benefits of file devices is that they allows multiple
concurrent readers of a volume.
