HP Data Protector Operations Guide

About this document
This document is intended for backup, system or storage operators and administrators, who are
new to Data Protector and are performing common backup tasks. It covers frequently performed
maintenance tasks, and provides some configuration recommendations and best practices on how
to set up an effective and efficient backup environment. This is not intended to replace any
existing documentation. For other Data Protector documentation, please refer to
www.hp.com/support/manuals.
The role of a backup operator is to be in charge of daily tasks such as making sure backups
complete successfully, tapes are ejected and scratch tapes are entered, and so on. Backup
environments present many challenges that are often overlooked simply because we are too
occupied with operations. There are many areas where a backup administrator can bring value to
an organization beyond being the keeper of the data.

A Data Protector Cell consists of a Cell Manager system the systems that are to have their backup
and restored tasks managed by it.
The basic HP Data Protector implementation utilizes only two architecture layers, the Cell
Manager, and the Cell Client layers. The Cell Console (GUI) is installed on the Cell Manager but
it may be distributed on multiple client systems as well.
The architecture is highly scalable and lends itself to the simplest single-system configuration, right
up to the most complex multi-system, multi-site enterprise-wide solution. With centralized
administration capabilities (managed locally or remotely) and a client/server-based architecture,
Data Protector provides the ability to globally support automated backup and restore for up to
tens of thousands of enterprise-wide network systems.
