I use "cross mount points" but do not select "follow NFS"
since SAN volumes that are direct attached can typically** only be read
by a single host, the host that is attached will backup that volume, as
it is seen by the system as local, not NFS.....if a volume is seen my
multiple hosts, it is usually mounted by those hosts as an NFS share, so
the "follow NFS" options turned off takes care of that.....the NFS share
if from a UNIX host is backed up via that host, and if from a Data mover
type NAS gateway, is backed up via NDMP.
so basically, most of my unix policies read only "/" in the backups
selections list, and have "cross mount points" but NOT "follow NFS"
selected.

** in cases where a SAN LUN is shared between two systems, as in a
global filesystem shared between the nodes of a cluster, that data is
backed up only once, via the virtual server name that fails over from
node to node, so in any situation, that FS is available to backup only
via the physical node that is hosting the clustered service.
In this case, the "virtual service" has a policy that explcitly
specifies the path that fails over, and the physical cluster nodes have
a separate policy which explicitly specify the non-shared local
filesystems to backup on each physical node.

Subject: [Veritas-bu] Unix policy's
Nb 5.0 mp6 Solaris 9
Our master runs on UNIX but most of the servers we back up are
window based servers using the "all local drives" option. We have about
400 UNIX servers that we do back up and many of these have mounts points
to our EMC storage. What I would like to know is how others backup up
UNIX servers and cross mounts points without duplicating what data they
back up. Many of our UNIX servers only get certain file systems backed
up. Many of our UNIX servers mount to the same space on EMC. So If I
create a policy that crosses mount points I will be backing up the same
date many times over. We are in the process of condensing the number of
policy's we have and combining many into 1 or 2 generic policies for
easy management. But it is becoming clear that not all of our UNIX
servers can use the "all local drives" option and many cannot have cross
mount points. So I was curious how others handle this situation within
their environments. Any thoughts?
Thanks
Greg
