You might also choose to use a combination of network and local backup jobs. Do this
when critical data resides on client computers and servers and you do not have a
removable storage media device for each computer. In this situation, users should perform
a local backup and store their backup files on a server. You then back up the
server.
Real World Backups on Large Networks
If you are working for a company with a large network, it is likely that a sophisticated
backup infrastructure is already in place. More than likely, users store their
important documents on file servers rather than on their local computers, and
those file servers are backed up daily. Make sure you understand the backup system
that exists on a network before you create a backup plan of your own.
On large networks, you are more likely to use the Backup utility as a precaution
before troubleshooting users’ computers—an extra step to make sure that you
can restore the computer should troubleshooting go wrong. On smaller networks,
it may still be advantageous to centralize user documents on a file server, but
more likely users will store documents on their own computers. In this case, you
should consider backing up client computers to a file server daily and also backing
up the data on the file server to a removable storage medium.
Another challenge of backing up large networks is planning for notebook computers.
Notebook users often disconnect their computer from the network to take
their computers home at night or on trips with them. As a result, notebooks do
not always fit into the same backup scheme as desktop computers. Although
notebook users can connect to the network and initiate a more traditional backup
to a network server, you should consider planning for a backup system that notebook
users can use while they are disconnected from the main network. Depending
on the amount of data that a notebook user stores, you might consider
providing users with an external hard drive or a CD writer, or even have them
connect to the company network (or an Internet backup location) periodically to
back up data. If notebook users have small numbers of files that they work on
while away, they can even back data up by e-mail.
Types of Backup Operations
Lesson 1 Using the Backup Utility
The Backup Utility provides five types of backup operations that define which data
is backed up, such as only those files that have changed since the last backup (see
Figure 20-3).
