Hi,
we are doing (nearly) the same.
Offline backup of our ~60GB production DB (Oracle 8.1.7), restore on our
customizing
system.
Backup with 2 channels to 3590 drives. TSM Servers is 4.2.2.8 and TDP is 2.2.1.
Backup and restore time are about 1 hour.
Is the hardware of your clone different to your production system?
I think you should check all components in your setup (CPU, memory, disk I/O,
network configuration, TDP config files ..)
Try to FTP a big file to this server. If it's faster it could be a TDP problem,
otherwise
I would check hardware and network.
What OS are you running on (W2K, Unix ..)?
