Apple 550 series Personal Computer User Manual


 
If your computer does not have a CD-ROM drive, use the application program
Apple Backup to copy the entire contents of your Macintosh hard disk to
floppy disks. Keeping this backup copy up-to-date will protect you in case
information on your hard disk is accidentally lost or damaged. You should
update your backup copy at least once a month, and in between full backups
you should store copies of important documents on floppy disks.
If something happens to the information on your hard disk, you can use the
backup copy you made to put the information back to your hard disk. To do
this, you use the Apple Restore program that came with your Macintosh.
(See the following sections for instructions on using Apple Backup and Apple
Restore.)
It’s a good idea to keep two sets of backup copies, and to alternate between
them (using one set one month, and the other the next) when updating your
backup copy. This protects you from losing files in the unlikely event that a
problem damages the files on both your internal hard disk and your backup
set of floppy disks.
You can also purchase a backup program with additional features that make
copying faster. (For example, some programs have a feature that lets you copy
only the new and changed information on your hard disk.)
