Subject: [Veritas-bu] Buffer settings


Environment : Netbackup Datacenter 4.5 MP1, master on W2K and media servers
on W2K and NT, 4 SSO drives

We are experiencing some performance problems. Most of the backups run, but
we don't get the speed we expect. There is one specific server (W2K) which
has an Exchange agent configured for individual mailbox backups (about 2700
mailboxes). That backup takes a very long time, but it works (about 11
hours for almost 60Gb). There is also a normal file backup scheduled and
that one never works. The backup starts and after a while aborts with code
41 (network timeout). Sometimes the backup not even starts.

I found some documents on the Veritas support site which talks about
several buffer settings. However, these documents are for Netbackup 3.4.

Are there some recommendations for these buffer settings ? I'm especially
looking at tape buffer settings (SIZE_DATA_BUFFERS and NUMBER_DATA_BUFFERS)
as this specific server is a media server with no clients attached to it
and thus only backups itself.

Bruno
