Using the BACKUP Command
Use the BACKUP command to back up the data on your hard
disk. It provides a convenient and efficient way to copy the
files on your hard disk. BACKUP allows you to do the
following:
Split large files across two or more diskettes
Copy
only those files
chat
have been modified since the
most recent backup
Copy only those files that have been created (or modified)
after a specified date
Copy files in the current directory together with files in all
subdirectories of the current directory
Format diskettes while copying files.
Unlike DISKCOPY and COPY, which make readable copies of
files, BACKUP creates files that you cannot access 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 57 360KB diskettes to copy
a 20MB hard disk that is completely full.
See your MS-DOS Reference Manual for complete instructions
on
using
BACKUP.
