Using the BACKUP Command
The BACKUP command offers several conveniences for archival
purposes. It allows you to do the following:
l
Split large files across two or more diskettes
l
Copy only those files that have been modified since the most
recent backup
l
Copy only those files that have been created (or last modified)
after a specified date
l
Copy files in the current directory together with files in all
subdirectories of the current directory
l
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
