Guidelines for setting up a NetBackup LiveUpdate server

A NetBackup LiveUpdate server does not require installation of any special software. The NetBackup software is also not required on the NetBackup LiveUpdate server.

The following describes the guidelines and requirements for setting up a NetBackup LiveUpdate server:

Server platform

A NetBackup LiveUpdate server can be any Windows or UNIX host.

Server configuration

A LiveUpdate server must be set up in one of the following ways:

  • As an HTTP or an HTTPS server.

    HTTPS servers must use a signed certificate by a certificate authority.

  • As a shared disk or a partition that is accessible by all NetBackup LiveUpdate hosts (server or client) that you want to update.


Currently, using a Windows shared disk requires the share to be set up as a null share. For more details, refer to the following tech note at


Some web server software allows the administrator to limit the file types the web server can serve. The LiveUpdate server must serve both zip and flg file types correctly for LiveUpdate polices to finish successfully. Failure to serve these file types causes LiveUpdate jobs to fail.

Environments with an existing LiveUpdate server

If you have a local dedicated LiveUpdate server for other Veritas products like Veritas Endpoint Security or Veritas AntiVirus, be aware of potential conflicts.

To avoid conflicts, take one of the following actions:

  • Download NetBackup Release Updates to a different directory on your local Veritas LiveUpdate server.

  • Designate a different computer as your NetBackup LiveUpdate server.
