Using The Backup Command; Using The Epson Help Program - Epson 20 User Manual

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
l
Copy only those files that have been modified since the most
l
recent backup
Copy only those files that have been created (or last modified)
l
after a specified date
Copy files in the current directory together with files in all
l
subdirectories of the current directory
Format diskettes "on the fly" (while it is copying files).
l
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

The Epson HELP program provides online information on MS-DOS
commands and utility programs. You can use HELP in either of two
ways:
You can type HELP at the command prompt and press
l
display the HELP menu
You can bypass the menu by typing HELP plus the name of the
l
command you want information about.
