To add to Ed’s response, with Windows 2008 you will also
need a job for each service or application (or a entry in a job for each service)
configured in your cluster unless you have turned strict name checking off (on
by default). Strict name checking means that only connections made
through the virtual server name can see the resources (e.g. disks) assigned to
the service.
An Example
Say you have a clustered file server called File_Server which
has multiple file server services named accounting_files and sales_files, your
Netbackup policy may look something like this:
Clients:
Accounting_files
Sales_files
Backup Selections:
All_Local_Drives

Thanks for the comments
– the part about restores – tells me I do want
Physical/Physical/Virtual
However – note:
Physical-2 did NOT give errors for the resources not being there. Which is what
I expected (2003 servers I know will give errors)
And in fact ONLY give
me 2 jobs C:\ and SCC
And I know the cluster
works as of right now all resources are on Physical-2 today.
So I was just wondering
if there was that much of a difference in a Cluster from 2003 to 2008.
Again thanks for your
comments.

Need a little info from a windows person on
cluster backups.
With 2003 if we did a cluster backup you did
Physical-1 - C:\ and System state
Physical-2 - C:\ and System State
Virtual-3 - All resources that belong to the virtual
And maybe a Virtual-4 and all of its resources.
Now with 2008 - while I was on PTO someone else put in a new clustered server
for backups, but did not follow the above method.
Instead they did
Physical-1 - All Local Drives
Physical-2 - All Local Drives
-------
Now the part that surprised me is that
Physical-1 got all the Resources plus the C and SS
And Physical-2 just go the C and SS
-----------------
My question -
Is it still (for 2008 servers) correct to set up a clustered server backup
getting both the physical and virtual server names.
Or does it work correctly just doing all local drives on the physical names?
What the new person did works but is wrong. Your virtual resources are
being backed up by physical1. When the resources migrate to physical2,
they'll automatically get full backups. At restore time, you have to
figure out which node the resources were on by searching the backups for both
physical1 and physical2 and piecing together your restore recovery.
In addition, you should be seeing status 71 errors for the backups of the
resources on physical2 because the disks are seen by bpmount but can't be
backed up.
NetBackup makes no attempt to figure out what virtual servers have what
resources. It's why I continue to claim that NBU *tolerates*
active/passive clusters but doesn't really *support* them. The same holds
true of Veritas clusters.
