Some people swear by the one-client, one-policy method.  I'm not one of
them.

The only reason I can see to do this is the ease of turning off backups
for a client.  In 9+ years of doing Netbackup, I think I've done this
less than a half-dozen times.  Even with multiple clients per policy,
you can do this with a "bpclient" command by setting "jobs per client"
to zero.

I like grouping.  I have 5 unix policies & 5 windows policies that
contain the great majority of my clients.  Each policy has a different
full backup night so I distribute my full backups across the week.  I
try to add clients to each policy based on the volume each policy does,
adding a new client to the policy with the current, least volume of
weekly backups. (I've got a little shell script that prints out one
week's totals that I use.) 

My filelists for backup are "/" with "Cross mountpoints" checked and I
manage what shouldn't be backed up via exclude lists.  If somebody
alters a server, changes the mountpoints, etc. the policies just catch
the change auto-magically.

Now, all that said, about 20% of my servers need special treatment.
Firewalled servers can't back up to anything but my central master
server (firewall rules) so they need different storage units.  I have a
pair of policies for firewalled servers as a result.

I have a group of NT servers that only need the "C" & "D" drives backed
up so their in their own policy with a fixed include list.'

There's a couple more one-off policies for special-purpose or
"special-needs" servers.

But, in general, I like the use of multiple clients per policy and think
it great reduces administration time.

We're discussing creating two policies to backup all of our
clients...one for all Windows servers and one for all Unix servers.  I
think this would make administration much easier.  Can any of you give
me the pros and cons of using only one policy?

Thanks,
