Re: [Veritas-bu] Need to backup a server in the extranet.

[Marianne Van Den Berg]

You DON'T need all of those in NBU 6.0 and above...

For client, you ONLY need vnetd (13724) in both directions.
If there's a media server behind the firewall, you need PBX (1556) as
well between master & media.

[Veritas-bu] VSP versus VSS

[pranav batra]

Hello Geeks,
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 ?
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?
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?
==Please 
provide me any valuable information on this.
Thanks in advance!!


Thanks and Regards

Pranav Batra

Re: [Veritas-bu] RMAN crosscheck - SOLVED

[Lightner, Jeff]

I was on vacation last week.

 

Our DBA solved the problem she was having here.

 

It was the incorrect values for variable NB_ORA_CLIENT in the crosscheck
script which used the real hostname instead of the backup LAN hostname
which the backup/restore scripts use.

 

For most of our hosts we have a separate backup LAN.   To distinguish
path over the backup LAN as opposed to the primary LAN we typically
suffix the hostname with a "b".  So if we had a server named tiger (used
for primary LAN) we would do backups/restores using tigerb (backup LAN).
In her issue the crosscheck script had "tiger" and when she changed it
to "tigerb" which is what was in the backup/restore scripts then it
worked properly.

Are you sure RMAN actually knows about the tape an image is on? If it
does, that is just silly. It should just ask for a backupid, then NBU
will give it the correct tape, regardless of whether it's a duped or
vault copy or whatever. I've always been sure that that's the way it
worked (Although, I'm not a DBA and don't know that much about RMAN). 

 

I think you're right, it just keeps the Media ID.

It's been a few months since I have looked closely at it.

 

Regarding vaulted tapes:  RMAN will not know that a tape has been
vaulted,

so it will have the wrong media ID for requesting the tape.

 

If the tapes are restored into the NBU catalog, RMAN will then ask for
the 

correct backup pieces by name.

 

This not an issue with RMAN, as the API has that capability, at least 

according to the docs.

 

It just has not been implemented by Veritas.

 

This would bear further investigation, as that situation may have
changed 

since I last looked into it.

 

Does RMAN also track disk STUs? I know in our environment, we
write all our Oracle archive log backups to a DSSU, then they get moved
out to tape and deleted from the DSSU within a day or so. We restore
regularly (to development), and it always works fine, regardless of
whether the archive log backups are still on disk or have been moved to
tape. Does that mean RMAN is aware of the destage process? I highly
doubt it.

 

There is a way for RMAN in later version to track backups that are
staged to disk and

then backed up on to tape.

 

I have never used it, and don't know any details about it.

Hello Geeks,
I am looking for the Process of VSP and VSS.
How these two are diffrent in their process:-What is the exact process which

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).

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

[Spencer O'Donnell]

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.

Re: [Veritas-bu] VSP versus VSS

[Herbert.George]

>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)
