Protecting the information on a disk

Your computer’s hard disk comes with a lot of valuable information already stored on it, including system software and some application programs. If you had a valuable document like a birth certificate, you’d probably make an extra copy of it for safekeeping. Similarly, you should make a copy of the information on your hard disk for safekeeping. (The extra copy is called a backup, and the process of making the copy is called backing up.)

Once you have a backup, you’re protected from accidentally losing the information on your hard disk. In the unlikely event that something happens to your hard disk, you can easily get the information back.

Backing up your files

You can back up the work you store on a hard disk by copying individual files to another disk in the usual way (dragging the files’ icons to the icon of the other disk). You can back up the contents of an entire floppy disk by dragging its icon to another floppy disk or hard disk icon.

If your computer has a CD-ROM drive, you also received the Macintosh Performa CD, which contains a backup copy of all the software that came with your computer. You should make backup copies of the documents you create. If you alter the contents of your System Folder, you may also want to use Apple Backup and Apple Restore to preserve the contents of your hard disk. (See the following sections for instructions on using Apple Backup and Apple Restore.)
