Netbackup TuningDon:

Check your exclude list through the registry. Make sure there isn't a space
before the exclude list.

And there really isn't a way to change it per client.  As you are aware, the
NDB and SDB are per media server.  If this client was upgrade to be a media
server, then you could control the NDB and SDB for it only and make its
storage unit DEMAND only and only its class requests it.  But that might not
be reasonable.  Unfortunately it the nature of the beast.

Sorry, I'm not much help here for you.

  Subject: [Veritas-bu] Netbackup Tuning


  I have a couple of problems related to Netbackup performance. We are
running Netbackup Datacenter 3.4.1 on Win2K servers. In order to increase
performance tuning I increased the number of buffers and the size of them.
This worked great for most servers being backed up with the exception of 1
client. This client has hundreds of thousands of small 1K files. The backup
is taking about 8 to 10 hours to backup about 10GB of data.

  I don't really need to back these up as they get backed up in separate
backup for DR purposes. I added the directory of these files into the
exclude list for this backup class but Netbackup is still backing them up.
Is there any reason  why Netbackup wouldn't recognize my exclude list.

  Secondly, the waiting for full buffers on this server is extremely high. I
remember reading in here that to tune Netbackup to backup alot of small
files you should decrease the size of the buffers. Is there a way to do this
for this client only while still leaving the other clients to use the
increased buffer size or can you only set this on the master.

  Any help would be appreciated.
