Lesson Summary

■

A network backup solution consists of backup drives, backup software, and a

backup plan.

■

When evaluating backup hardware, higher speed and greater capacity nearly

always means higher price.

■

The function of the backup software is to enable the administrator to select the tar-

gets for backup and then send them to the tape drive or other device.

■

Incremental and differential backup jobs save tape by backing up only the files that

have changed since the last backup, based on the status of each file’s archive bit.

■

Performing regular test restores is a crucial part of backup administration.

■

Volume shadow copy is a Window Server 2003 feature that enables users to access

multiple copies of files they have accidentally deleted or damaged.

Case Scenario Exercise

You are the network infrastructure design specialist for Litware Inc., a manufacturer of

specialized scientific software products, and you have already created a network

design for their new office building, as described in the Case Scenario Exercise in

Chapter 1. The office building is a three-story brick structure built in the late 1940s,

which has since been retrofitted by various tenants with several different types of net-

work cabling. Your network design for the building calls for the installation of four

LANs, each of which is connected to a fifth, backbone network.

You are designing a backup solution for the building’s entire internetwork. To make it

easier to back up valuable company data, you have supplied each of the network’s 125

users with a home folder on a shared server drive, and have instructed the users to

store all their data files in their home folders. You have also created disk quotas grant­

ing each user a maximum of 1 gigabyte of storage space.

Because of this arrangement, you will be backing up only the network servers, not user

workstations. In addition to the file servers hosting the users’ home folders, there are also

six Web servers, each with a 40 GB drive, a database server with an 80 GB drive hosting

approximately 10 GB of database files, and an e-mail server with 25 GB of mail archives.

Based on this information, answer the following questions:
