Apple Macintosh PowerBook 145B - Manual (Page 24)

Backing up your hard disk
This section describes how to protect the software on your
computer’s hard disk.
Why back up?
Your computer’s hard disk comes with valuable information
stored on it, including the
system software (which operates the
computer) and some programs. You should make a copy of the
information on your hard disk for safekeeping, using the
PowerBook 145B Backup program supplied on your hard disk.
(The extra copy is called a backup, and the process of making the
copy is called backing up.)
You should also make a copy of your System Folder. If the System
Folder on the hard disk becomes damaged, you can quickly
restore it from your backup copy.
To restore information to your hard disk, you can use the
PowerBook 145B Restore program that came with your
Macintosh. See “Restoring the Information on Your Hard Disk” in
Chapter 8.
