Ll 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.
