Preface

About this guide

This guide describes how to protect, back up, restore, and copy data between Network Appliance® filers that run Data ONTAP® software and that are Serving Data by Design^TM. This guide covers all filer models.

Audience

This guide is for system administrators who are familiar with operating systems that run on the filer's clients, such as UNIX®, Windows 95^TM, Windows NT®, and Windows® 2000. It also assumes that you are familiar with how to configure the filer and how the NFS, CIFS, and HTTP protocols are used for file sharing or transfers. This guide does not cover basic system or network administration topics, such as IP addressing, routing, and network topology; it emphasizes the characteristics of the NetApp® filer.

Terminology

Network Appliance's storage products (filer, FAS appliances, and NearStore® systems) are all storage systems. All these products are also sometimes called filers or storage appliances.

This guide uses the term "type" to mean pressing one or more keys on the keyboard. It uses the term "enter" to mean pressing one or more keys and then pressing the Enter key.

Command conventions

You can enter filer commands on the system console or from any client that can obtain access to the filer using a Telnet session. In examples that illustrate commands executed on a UNIX workstation, the command syntax and output might differ, depending on your version of UNIX.

The following table lists different character formats used in this guide to set off special information.

Formatting convention	Type of information
