Backing Up
It’s very important to keep backup diskettes containing copies of the
files you create. You can copy data and program files several ways:
l
You can use the COPY or XCOPY command to copy individual
files or groups of files.
l
You can use the DISKCOPY command to make an exact
duplicate of a diskette.
l
You can use the BACKUP command to back up hard disk files to
diskettes. Because BACKUP can split large files across two or
more diskettes, it makes more efficient use of diskette space than
COPY It also gives you a way to back up files that are larger than
the capacity of your diskettes.
DISKCOPY and BACKUP are described below. The COPY
command is described in the previous section, “Copying Files.” See
your MS-DOS Reference Manual for information on XCOPY.
Using the DISKCOPY Command
The DISKCOPY command lets you copy all the files on one diskette
to another diskette. (You cannot use DISKCOPY to copy to or from
a hard disk.) The procedure for copying diskettes depends on whether
you have one or two diskette drives. Follow the instructions below for
your configuration.
Using DISKCOPY with one diskette drive
1. Make sure your original diskette is write-protected. (See Chapter
4 for instructions.)
