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 (IOSTAT OBSERVATION WHEN THE
SYSTEM IS BUSY BUT BACKUP IS TAKEN IN NIGHT WHEN SYSTEM IS HIGH ON
RESOURCES)
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.
