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 or XCOPY. It also allows you to
back up files that are larger than the capacity of your
diskettes. To access files created with BACKUP, you use
the RESTORE command.
DISKCOPY, BACKUP, and RESTORE are described below.
“Copying Files,” earlier in this chapter, describes the COPY
command. See your MS-DOS Reference Manual for
information on XCOPY.
Note
The MS-DOS Shell and the Epson MENU program provide
easy ways to perform the functions listed above. See your
MS-DOS Shell User’s Guide and “Using the Epson MENU
Program,” later in this chapter.
Using the DISKCOPY Command
The DISKCOPY command lets you make an exact copy of a
diskette. (You cannot use DISKCOPY to copy to or from a
hard disk.) Because this procedure copies the data byte by byte,
the two diskettes must be of the same type. For example, you
cannot use DISKCOPY to copy a 720KB diskette to a 1.44MB
diskette or a 360KB diskette to a 1.2MB diskette. (Use the
COPY command to copy files between different types of
diskettes and to copy files to or from a hard disk.)
If the diskette you are copying to has never been formatted,
DISKCOPY formats it automatically before copying the data.
The procedure for copying diskettes depends on whether you
have one or two diskette drives. Follow the instructions below
for your configuration.
