[Veritas-bu] Backing up cluster after failover
2009-06-12 17:49:27
I'll take a stab at it: Don't think "drives" think "groups"
Remember that Windows Cluster drives do not "float" around on their own- they
are part of a Cluster Group. That group also includes IP addresses- you can
and should have a dedicated backup IP address for each Cluster Group that
resolves to a unique name in the DNS. Point your backups at the Cluster Group
DNS name, NOT the physical node names.
Since all the resources in a Cluster Group always move together, your backups
will follow the Cluster Group Backup IP address, and the expected drives will
always be there (unless they fail to come online- but that's a different
problem).
As long as your Netbackup Clients on the physical nodes have the correct
media/master server entries, they can remain blissfully ignorant of what's
going on- Netbackup will take care of it.
You'll need a separate policy for each Cluster Group, since "All_LOCAL_DRIVES"
becomes useless- all drives must be explicitly listed, and you'll also need
separate system policies to protect the OS on the physical nodes (limit those
to the C drive and the system state).
Just remember that restores won't work right from the client side under normal
settings- you'll want to run those from the media/master. (you can get around
that, but it's a pain).
