We purchased a Teredata database system.
It currently is in test/dev stage with little data.
We don't really know the ultimate backup requirements.
To get things started we setup a simple backup system:

   Teradata
    -> to Bar server (Win) with TSM interface sftw
    -> to TSM server (AIX)
    -> to filepool on DataDomain (getting ~5x dedup)

   From the Bar server to TSM server is a standard 1GB ethernet.

Now we need to scale up/out!

The consultants are saying we will need to backup 30TB in a 6hr window,
but maybe has high as 50TB in 6hr.
That is (roughly):
         30TB in 6hr = 1,400 MB/sec
         50TB in 6hr = 2,300 MB/sec

So we need to design a TSM backup system to support this.

My thoughts:

1) Put a storage agent on the Bar server (Win server)
     and feed a VTL via 4x8gb san connections via a bunch of virtual tape.

2) Put the TSM server directly on the Bar server for just
     local tape and still feed a VTL as above.
     No library sharing.

3) I'd really like to not use tape (even virtual tape),
     but I can't think of any way to feed file devices
     with that throughput.

I'd appreciate any thought/comments anyone might have!

Thanks

Rick
