Richard,
How are these dumps created? If they are created using DD or something similar, you
may be able to get some relief from using RMAN to create disk dumps. RMAN only backs
up used database pages. It also has options to do incremental and differential
backups. These are really options that you should be exploring if your window is
really that tight.

The amount of data is the same everday 500GB full backup. I'm using one SSA
card in the tsm system. I could get Gig cards if I have proof that I'm
maxing out the current 100mb cards in the system and I don't seem to be
doing that. The tsm server is plugged into the same switch has the backup
server and on the same ip subnet. Also, the database files that I'm backing
up are just oracle dump files. The tsm serve is also running aix 4.3.3.

We are backing up 2 servers of capacity 1.2 TB everyday. We have shark
system and flash copy is implemented on shark. Without client interference
we backup 1.2 Gig to TSM. It's running with 6 drives. No LAN/Free. But it's
Client/Free backup. To restore we have placed Gbit Interfaces in Client and
TSM Server.
You need to give more information of your server and database.
Are you doing incremental or full backup and which database you have?
If incremental how much data is changed everyday?
Can you afford GBit interface between data server and TSM? ( IT needs 2
adapter and 1 switch)
How many drives your library have? How many SSA adapters are installed in
server?
Thank you,

Hi
If I am correct IBM offers LAN free backup which is faster .But need to
purchase additional s/w.

Subject: 500GB Backup
I need to backup a 500GB database and my current setup is my tsm server is
on the same ip subnet has the database server. Tsm is connected to 500GB of
SSA storage with 5 RAID5 sets with two 50GB tsm volumes on each raid set.
My though put to the disk only seems to be 9000 kB/s. Which doesn't seem
very high to me. My backup time is about 6 hours. Does anyone have any
better senarios for backing up this amount of data in the smallest amount of
time soon. I am going to be backing up a 1Tb per day and I need to get me
backup times to the lowest. Does anyone have any suggestions on how to do
that.
Thanks
