Tuning network performance
If possible, use a dedicated local area network
(LAN) or a storage area network (SAN) for backup operations. Keep
device drivers for network components updated to take advantage of
the latest fixes and improvements. Consider the IBM
Spectrum Protect options
that can help you tune how the clients and the server use the network.
Ensure that you understand how TCP/IP works and review the information
about TCP flow control and the sliding window.
