Veritas NetBackup™ for DB2 Administrator's Guide

Use the NET_BUFFER_SZ file to speed up a slow restore

If file restores are slow and your NetBackup master server is a UNIX machine, you can increase file restore speeds. Create a file that is called NET_BUFFER_SZ on the NetBackup master server in the NetBackup install directory.

To create the NET_BUFFER_SZ file

  1. Log into a UNIX master server.
  2. Use vi(1) or another editor to create file /usr/openv/netbackup/NET_BUFFER_SZ.
  3. Add a line that specifies the socket size, in bytes.

    For example:

    32768 bytes = 32K
  4. Save and close the file.
