Backup
Backup procedures are important for the efficient and
effective use of your computer. Protect your program and
data files with regular backup procedures. The Setup utility
provides a backup reminder option (see Chapter 2).
See your MS-DOS and Windows documentation for
information about backup procedures. Make backup copies
of your program and data files that are on diskette and on
the hard disk.
The standard practice for diskette backup is to copy each
diskette, store the original in a safe place, and use the copy
as your working diskette. You can use the MS-DOS
DISKCOPY command for making copies of your diskettes.
See your MS-DOS documentation for information about
using the command.
