In 2008 the cluster config and cluster db are backed up via VSS, as a
part of the systemstate. We are just now moving to 2008 so I haven't
done any testing with it yet to see how/if TSM has a recommended
solution. However, seeing that it is part of the SS you should be able
to test it by running a backup and then either querying the components
of the system state (or use the GUI) to see if it is present. 

On another note:
Many opinions are that in most cases there is little need to restore the
clusterdb from backup since 2008 clusters use the Majority Node Set
model. This means that instead of the cluster config & db being on a
quorum drive each node of the cluster has its own copy locally, as well
as backup copies stored with a "tmp" file extension. When a node is
recovered or rebuilt and re-joined into the cluster the surviving nodes
provide the new node a copy of the current database (following the
process in links below).

Simply stated a copy of the db (and "tmp" backups) are located locally
on every node of the cluster.

This may help:

Hi all,



I'm running a MX cluster on two Windows 2008 R2 Enterprise servers.

TSM B/A client 5.5.2.12 is installed on both.

How do I backup the MS clusterdb?



Thanks and best regards,

Rainer
