Hi guys,

I have a windows file server I am currently backing up that I am 
expierencing very low throughput on.

The volume in question is a 3.3TB partition with about 2.6TB in use.

It's currently taking 66 hours to do a full of this file system to an LTO 
4 tape.

This is a network based backup.

I've been doing tuning, and the network path is clean (The exchange server 
in the same rack on the same switch gets 8-9x the performance when it 
gets backed up) - it's gig-e all the way and is unloaded.

One thing I was considering is that this may be an issue with the Virus 
scanner.  Being a file server this contains a TON of files (9.8 million 
files totaling 2.9TB), and I'm wondering if the virus scanner is causing 
this.

The tuning guide suggests I should turn anti-virus off, but my security 
director balked at this idea.

I was wondering what some of you with "way more data" than I have do.  Do 
you run virus scan on your fileservers?  Do you back them up in a 
different way than I do?  I need single file recovery.

Any other tuning advice you can give?

Jason
