Chapter 2: Backing Up Files
You can do two types of backups with Legato NetWorker ClientPak for
MPE/iX: server-initiated backups and client-initiated backups. This chapter
describes how to do client-initiated backups. This chapter also briefly
discusses server-initiated backups of an MPE client. However, for
comprehensive information on how to configure your MPE client to do server-
initiated backups, refer to the Legato NetWorker Administrator’s Guide that is
distributed with the NetWorker server software.
Server-Initiated Backups
Once your system administrator installs NetWorker on your HP 3000 and
configures a NetWorker server to recognize your HP 3000 as a NetWorker client,
then NetWorker does server-initiated backups of your HP 3000.
Ideally, the system administrator should configure your HP 3000 as two MPE
clients on the NetWorker server: one for the sake of performing server-
initiated backups of specific files and directories and one for performing
server-initiated backups of MPE volume sets. Refer to “Configuring the Server”
in the Legato NetWorker ClientPak for MPE/iX Installation Guide for more
information on configuring a NetWorker MPE client on a NetWorker server. The
processing for configuring an MPE client for doing server-initiated backups of MPE
files and directories is standard. Refer to Chapter 2, “Getting Started,” in the Legato
NetWorker Administrator’s Guide for information on the default configuration for a
client on a NetWorker server.
For server-initiated backups, NetWorker creates index entries and a media database
that track the media location of each client file. NetWorker maintains two types of
indexes on the server: a file index and a media index. The file index stores information
about the files backed up by NetWorker. The media index stores information about
NetWorker media and the save sets stored on the media.
