I agree with Simon.
I want to add that netbackup 7 clients does not have VSP.

VSP is not good. I would turn it off.
For older legacy systems, it was fine, but it can cause a server to
have as it tries to take a snapshot of a drive. And it can sit there for ages!
Personally, Win2k3 should be using VSS - Same as Win2k8
Might well be wrong here, but by default, the VSP option is
enabled, but I think in 6.5.6, it is no longer enabled by default.
Generally I have found VSP does not play when you limit the
size its cache files can grow too.
As you said, best to make sure you have a ton of disk
space on the drive it is placing them on, and try not to run too many jobs at
once as it will kill your throughput and put a load on the machine. And even
make it non responsive !
you can also research tuning VSP, but for Win2k3 clients and
higher, why bother?? When VSS is much, much better. NBU Admin Guide Vol 1 is a
friend to talk to :-)

Subject: [Veritas-bu] VSP making server hung.
There
is one windows 2003 server and we are taking it's backup via VSP .
What
we have found that in last couple of weeks that when ever tha backup starts the
server gets hung.
PS:-We
have adequate free space in all of the drives.
When
i changed snapshot from VSP to VSS:-It started working fine.
Though
i know that VSS is recommended for 2003 servers but we were using VSP since
long and thuis server hang issue is very new.
Please
explain as i am a bit confused between VSP and VSS.
Does
VSP play any part in making the server hung?
Does
VSP deletes the nbu_vsp_cache after the reboot of the server ?
Or
it's something else that ia making the server hung ?
Thanks and Regards
