Apple Macintosh PowerBook 1400 - Manual (Page 75)

Tips for backing up all types of files
m You can back up an entire floppy disk by copying it to another floppy disk
or to a hard disk.
m You can use a commercial backup program to copy new and changed files
from a hard disk to another hard disk, to a tape drive, or to a series of
floppy disks.
m If your computer is on a network, you can back up files by copying them to
a shared disk on the network.
m You can back up files by copying them from one computer to the other
using SCSI disk mode. (See “Using Your Macintosh PowerBook as a
Hard Disk” in the “Connecting SCSI Devices” section in Chapter 3 for
more information on this procedure.)
Using “native” application programs
Your computer is compatible with nearly all application programs intended
for use with Macintosh computers. But certain programs are designed
especially for computers with PowerPC microprocessors. (These are
sometimes called “native” applications.) You’ll find that these programs take
best advantage of your computer’s speed.
Special memory requirements
Some native programs may be slightly larger than other programs and may
take up more memory. If you find that you are running out of memory when
you use programs designed for PowerPC microprocessors, you can use space
on your computer’s hard disk as additional memory. This feature is called
virtual memory. Your computer was developed to take advantage of the virtual
memory feature and comes with virtual memory turned on. For instructions
on how to use or increase hard disk space as memory, see the “Memory” topic
of Mac OS Guide, available in the Guide (h) menu.
You can also add more memory to your computer, as described in Appendix C.
