Re: [Veritas-bu] Windows Backup of C drive slow
2007-05-24 09:44:49
Jonathan,
I don't get failures... My backups of my C drive take a
very long time and back up no data (see below). I was wondering, since I
backup the C & D at the same time if the snapshot for D drive is being built
on C at the same time as C is trying to backup?!? That could explain
it.
So, I went and configured a quick policy to backup C drive
on that server by itself and it went quite fast! So, I am thinking I
should turn off multiplexing/multistreaming and just let it backup from top to
bottom.
What do you think?

You have to add the client to the list under Client
Attributes, then go over to the Windows Open File Backup tab and disable Open
File Backup There. 99% of my servers have no issues with open files.
The few that do, I've switched to VSS which sometimes works better than
VSP. If that doesn't work (occasionally backups fail with snapshot errors)
I select "Disable snapshot and continue" under error control. Using that
method, I've never had to disable open file on any windows server (although
several do fail I presume, and disable themselves for that backup
session.)
There was a way to do this I believe via the bpclient
command that was detailed several months ago, if you just want to disable it
across the board. I personally don't recommend this
however.

Jeff,
That I do know how to do. Go into the GUI and "Host
Properties","Master Servers", then select properties on your master
server. There is a "client attributes" tab under there you will find the
windows server listed and you can disable open file backups.

UNIX admin here.
How does one turn of VSP/VSS on Windows 2000/2003?
AV?
Also does this advice
only hold for Windows 2000/2003 or for any Windows server?
We have some backups
that go incredibly slowly and I’m thinking of suggesting this to the Windows
Admins here to do some testing.

First
thing, is to turn off VSP / VSS if its Windows 2000 / Windows
2003.
Any
AV, should be turned off.
Also
look for any large cache files created on your C: Drive - example being
vxfiVspcache_1.tmp (make sure you are set to view hidden or system
files).
Any
disk I/O software should be turned off.
Also,
try a backup policy (create a test one) that does JUST the C: drive on its own
for this particular client.

drive slow
Ok,
I am looking for help.
I
am running a Solaris 9 master server, with 5.1MP3. I have 8 windows
servers that I backup, 3 of them are 2000, and 5 of them are on 2003
SP2.
Well, I setup the policy for each
server to by ALL_LOCAL_DRIVES, and also turned on
Multistream/Multiplex.
So it kicks off 3 channels:
Shadow, C drive, D drive.
C
drive is 2 hardware mirrored disk, D drive is a hardware raid 5 of 4
disks.
Well, the C drive backup takes
forever! As an example from 1 server....
Shadow -- 4 mins (911,909
kbytes) C drive -- 2 hours 29 mins (49,461
kbytes) D drive -- 1 hour 54 mins
(95,458,574 kbytes)
My exclude list for this server
has the standard entries and a few that I have added. C:\Program
Files\VERITAS\NetBackup\bin\*.lock C:\Program
Files\VERITAS\NetBackup\bin\bprd.d\*.lock C:\Program
Files\VERITAS\NetBackup\bin\bpsched.d\*.lock C:\Program
Files\VERITAS\NetBackup\Temp C:\Program
Files\VERITAS\Volmgr\misc\* *.mdf *.ldf C:\Windows\NTUninstall*
C:\Windows\PCHEALTH
I
am trying to figure out why it takes so long to backup the C drive.
Should I be excluding something? I am at a point that I am going to
remove the C drive from the backup. SQLSERVER is running on this
box(s).
