Any additional I/O that can put a load on the file system during a
backup should be turned off, especially AV (even Symantec will tell you
this).
I have been away, so playing catch up with emails, but alot could also
depend on the type of files, the size of the files and the backbone
behind the system
SAN Media Server or Flashbackup (Both extension modules for NBU) could
help. But as a start, ensure no system or scheduled tasks are running,
turn off AV and any disk defrag software, or any software that could be
causing this.
ALSO, disable tracker.exe - I hate it!! By default, its on. (Start / RUN
and type msconfig.exe and in the startup tab disable tracker.exe)
Let us know how you get on

Subject: [Veritas-bu] Best Practice - Virus Scanning on windows FS's.
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
