Using the BACKUP Command

The BACKUP command offers several conveniences for archival

purposes. It allows you to do the following:

Split large files across two or more diskettes

Copy only those files that have been modified since the most

recent backup

Copy only those files that have been created (or last modified)

after a specified date

Copy files in the current directory together with files in all

subdirectories of the current directory

Format diskettes “on the fly” (while it is copying files).

Unlike DISKCOPY and COPY, which make readable copies of files,

BACKUP creates files that cannot be accessed directly. To return files

copied with the BACKUP command to their original locations on

the hard disk, you must use the RESTORE command.

Make sure you have enough diskettes to back up the data on your

hard disk drive. It takes about 27 1.2MB diskettes to copy a 32MB

hard disk partition that is completely full.

See your MS-DOS Reference Manual for complete instructions on

using BACKUP

Using the Epson HELP Program

commands and utility programs. You can use HELP in either of two

ways:

You can type HELP at the command prompt and press

Enter

You can bypass the menu by typing HELP plus the name of the

command you want information about.
