Backing Up Your Hard Disk
It is highly recommended that you make back up copies of your
valuable hard disk files regularly. Because hard disk drives are
fragile, they can sometimes be damaged. It is also possible to
erase some or all hard disk files through the use of incorrect
FORMAT and COPY commands. Backing up your files is the
only way you can be sure that you don’t lose information you
may have spent months or even years gathering.
Two external command programs on your MS-DOS install
diskette will help you back up your hard disk. The first,
BACKUP, will copy files from the hard disk onto diskettes.
The other, RESTORE, allows you to use the diskettes created
by the BACKUP program to reload the files back onto the
hard disk, if necessary. The following sections describe how to
use these two command programs.
The BACKUP Command
This command backs up one or more files from your hard disk
onto floppy diskettes. The diskettes must be formatted by the
MS-DOS FORMAT command. Do not use the /S switch when
formatting these diskettes. Disk space taken up by the inclusion
of the active MS-DOS routines would be wasted with the
BACKUP command.
Note
For information on formatting diskettes, see Chapter 5,
“Using Floppy Disks.”
