Copy your data diskettes regularly (preferably every day, or
every few hours if you’re creating a lot of data) to keep your
backup data current, then store the backup copies away from
your originals.
Chapter 1 describes how to use DISKCOPY to copy your
MS-DOS system diskettes. To make backups of other MS-DOS

instructions on using DISKCOPY and DU.

more information, see “Copying Data” in Chapter 3 and refer to
your MS-DOS reference manual.

“Preparing the hard disk for moving” in this chapter for
more information.
Working with a hard disk is very similar to working with a
diskette. MS-DOS treats files on a hard disk just like files on a
diskette. However, the hard disk provides several advantages:
