I was reading that section of the 6.5.6 release notes and I just couldn't quite 
understand it.  It seems to say that as of 6.5.6 Symantec have caused VSP to be 
automatically installed.  Previously we have always disabled it - we do Windows 
installs using silentclient.cmd, and that has an entry you can edit to stop it 
installing VSP.  So it seems to read that as a new feature in 6.5.6 you cannot 
stop it installing VSP?

It then goes on to say that at NetBackup 7.0 VSP is not supported....

Am I reading this right...6.5.6 will install VSP whether you like it or not, 
and so if you want to get back to the 'status quo' at e.g. 6.5.4 of not 
installing it, you must use this new VSP disable tool, or suddenly VSP is going 
to start running on all the 6.5.6 clients, in place of VSS?  There is a table 
on page 50/51 of the 6.5.6 document updates that shows the behaviour of Windows 
- it says "The following table describes the backup behavior based on the 
Windows Open
File Backup setting for the client and whether or not VSS is available on the 
client." - and in none of the cases is VSP run.  I'm guessing that they meant 
to say that the table applies *after the VSP disable tool is run* and that 
makes it really confusing.

Does anyone know what actually needs to be done after upgrading to 6.5.6 on 
Windows 2003, to make sure VSP is not going to run?

Also...the VSP Disable tool can be run "from a Windows master server or media 
server" - we don't use those, all our Master & Media are UNIX.  So what do we 
do?

From a recent case with Symantec support:

... in the NB_6.5.6 readme, might be something to consider.
===================
NetBackup 6.5.6 automatically installs the Veritas volume snapshot Provider
(VSP) method for Open File Backups. VSP is the default Open File Backup method 
in this release.
NetBackup 6.5.6 includes the VSP disable tool (bpvspdisable.exe) for
administrators to use to disable VSP on clients if it is not needed. The tool 
deletes the VSP cache files from the disk of the client system. All future VSP 
requests on those clients are redirected to use Microsoft native Volume Shadow 
Copy Service (VSS).
The VSP method for Open File Backups is not supported in NetBackup 7.0. Having 
run the VSP disable tool does not affect upgrading to NetBackup 7.0.
The VSP disable tool can be used on the following operating systems:
■ Windows Server 2000
■ Windows Server 2003 with Service Pack 2 (x86 and IA64)
■ Windows XP 32-bit and 64-bit (x86 and IA64)

May as well convert to VSS now. It is no longer there in 7.0. I swapped all my 
2003 and 2008 clients and things have never work3ed better, no more status code 
156 errors. There is a good vss enabler script on the Symantec Forums.

I have a small question on VSP/VSS.

As symantec recommends VSS for 2003 clients over VSP then why  it is the 
defauly snap-shot provider option ?

It's historical and is no longer the default in NetBackup 7.0.

Any specific reason for this recommendation as i can't find any tech note 
specifying why VSS:

They all just explain that VSS is for 2003 and VSP for 2000.
I agree but why?

Windows 2000 did not have a snapshot service provided by the operating system 
so Veritas had to write their own.  Microsoft added it in Windows 2003.

VSS has a HUGE advantage for the backup administrator because snapshots are now 
the responsibility of the server administrator, not the backup administrator.  
If snapshots fail, it's usually because the server administrator doesn't have 
something configured correctly or the admins have neglected to install patches 
to VSS (there are some but some Windows admins seem to install ONLY security 
patches and ignore all reliability/functionality fixes).

What happened two weeks ago:-There are our two cluster server and both got hung 
while getting backed up.
We are still looking for the root cause but couldn't find yet...The thing we 
suspect is that they were using VSP and when we changed snapshot provider to 
VSS( As they are 2003) ,backups and server both running fine from 2 weeks and 
didn't hung once.

Does VSP plays some part in making the server hung?
What could be the possible reasons?
Does VSP plays some part in making the CPU utilisation high?

VSP is evil.  Don't try and debug it - just quit using it.
