Hello Manel,

Support for Windows 2008 will require one of:

NetWorker 7.4 SP2 -- due in a week or two.
NetWorker Module for Microsoft Applications release 2.0 -- available as
of last week.

Thanks,
_Scott

Subject: [Networker] Backing up cluster resources in Windows Server 2008

Hello,

We have the following environment:

Legato Server, Windows 2003 R2, Legato 7.4.1

and we are trying to backup cluster resources in a Windows Server 2008 
Failover cluster formed by:

node1, Windows Server 2008 Enterprise, Legato 7.4.1
node2, Windows Server 2008 Enterprise, Legato 7.4.1

In this cluster we define the 'resource1' (associated with the F:\
volume).

We can backup without problems 'node1' and 'node2' by themselves. No 
problem with 2008. They are treated as normal clients (using VSS), etc.

We define a new client 'resource1' with saveset F:\ and with remote 
permissions assigned to system@node1 and system@node2 (the same we had 
for another cluster in Windows 2000).

OK. We launch the backup and it seems to start but it stays in the 
'contacting client' status for a long time. The correct tape is mounted,

etc.

If we abort the group, we get the following error:

* resource1:F:\ Additional System Files have been added for the Vista or

Longhorn platform.

So, it seems that Legato has detected the correct platform (Longhorn) 
but the backup doesn't start. We can contact the client from the server 
without problems:

And we can do a probe:

7241:savegrp: nsrim run recently, skipping

Any idea about what the problem could be?

Thanks.
