Akash,
        We are going to need a LOT more information on this performance
issue to try and help. If you wish to use the resources of this listserv (a
GREAT resource), we are going to need to know:
                1. TSM Server platform and level
                2. TSM release level
                3. Client platform and level
                4. What type of database is it that you're backing up?
                5. More information about the network: card type, switch
type, etc.
                6. disk subsystem on the TSM server
                7. Whether or not you're using RAID and what type
                8. Filesystem type on TSM server
                9. Disk subsystem on client
                10. Filesystem type on client

        If you provide this (for starters), we can try an help. Another
suggestion: if you would like to work with IBM/TSM software support, open a
PMR with IBM and ask for TSM performance assistance. Our department works
these PMRs and can try and assist.

Hi experts,

It has been observed that cold backup of database server is taking more time
from past 1 months.

In spite of the fact that we are having 2Gbps data transfer speed, no
simultaneous process is running on TSM backup server and no other database
backup is scheduled with the running backup.

Could anyone update about the certain parameters I can work around to reduce
the time or checked ti improve the performance?

Now its taking more than 10 hours for transferring 110 GB of data on LTO
tape where as previously it was taking less than 10 hours for transferring
120 GB of data.

Any help and suggestions are really appreciated.
