Re: [Networker] Performance Tuning backup

I have done monitoring and eliminated these as bottlenecks:
Server network
Tape drives
Memory
Possible bottlenecks:
Cpus (server has 4 xeon 2.8ghz with hyperthreading enabled)
Client network (doubt it since it has 2 gigabit nics in a team)
I feel this is either a cpu or networker tuning issue.

Hi all
I run legato 732 on win2003.
I have 6 fiber LTO2 tape drives.
The server has 4 cpus and 4GB ram, and 5 Gigabit nic cards in a team.
All my legato server settings are the default. Tape drive target
sessions
is 4.
I backup my lotus server daily, its 800gb and it takes 10 hours.
How can I increase the speed of this backup with tuning legato?
I do not think the network is the bottleneck as I recently added
more nic
cards and it didn't help.
Should I change target sessions or parallelism?
That depends on the bottleneck. What kind of throughput are you
getting to those tape drives during a typical backup period?
