Restoring data will work, but if you have to do a complete DR and restore
the entire cluster (server(s) and shared volumes) from tape, the volume
serials will be different (only need to be the same on the shared volumes)
if you reformat the existing shared volumes or go to new shared volumes.
Cluster software stores the vol serials and will not come up if they do not
match. (Make sense?)

Well this is my sort of DR plan in the event of a failure
1 x restore Server from disk image (taken on a regular basis)
1 x restore the Data from Netbackup to the Virtual Friendly names
As a precaution, I also have been taking backups of the CLUSTER named C:
drives and system state!
As long as the Data can be restored, I would have thought this would work?

Just remember, If you have a disaster on a cluster and do a DR, the volume
serial numbers for each volume must be the same after the DR as they were
when backed up, or the cluster will not come up. There is a tool from M$
that will allow you to get this info and change to serial numbers as needed.
We always had to document the serials and keep a copy of the doc offsite as
well as on site.

Subject: [Veritas-bu] Backuping Up Cluster 2003 Server
Hi again
Does anyone have any experience on backing up a cluster with NBU 5.x ?
I have a question that I would like to get confirmed as being the correct
answer, in the event of problems restoring the cluster!
Basic setup
Windows 2003 Server Cluster is known as CLUSTER01. The Nodes are known as
Cluster02 and Cluster03 as physical computer names. On top of this, they
also have "Virtual Names" known to the users as "Data" and "Personal"
At the moment, I have the Netbackup client installed on Cluster02 and
Cluster03 (As this is the physical computer names of the Servers).
Now, what I have been doing is performing backups using the "Virtual Names".
This has been working fine, without too many issues.
However, my question is this: Should I also be doing backups of the Physical
Computer Names or not?
Not knowing clustering that well, I was not entirely sure if this is the
correct process, but it does work!
Would be grateful for any information on this. I want to be 100% sure that
in the event of a disaster, I can safely recover the node or worse case, the
entire cluster.
Thanks for any comments
Simon
