disk. For example, if you have a subdirectory
named Mystuff in the root directory of your hard
disk, you can use BACKUP to copy it to a diskette.
With a formatted diskette in Drive A, type:
backup c :
\mystuf f a:
/ s
ENTER
Note: Unless you specify otherwise, using this
method causes MS-DOS to erase any files cur-
rently on the diskette used for the hard disk
backup. Be sure that you are using a newly format-
ted diskette or a diskette containing files you do
not want to keep.
To accomplish the same backup without erasing
files currently on the diskette, add the /a switch to
the command. The /a switch causes the BACKUP
command to add the new files to any existing files
on the diskette. In
MS-DOS,
a switch is always pre-
ceded by a slash (/) symbol. The same command
with the /a switch is:
backup c
:
\mystuf f a
:
/s/a
ENTER
The /s switch, used in the previous command, in-
structs MS-DOS to back up all the files in a direc-
tory and all the directories and files that branch
from that specified directory.
You can use the BACKUP command with the /s
switch to back up the entire hard disk to diskettes.
Before using this command, use the FORMAT
command to prepare enough diskettes to hold
all
the files you want to back up. To back up every-
thing on Drive C, type:
backup c :
\ a
:
/ s
ENTER
The backward slash (\) is an abbreviation for the
root directory of any disk. This command line in-
structs MS-DOS to copy all files from the root di-
rectory of Drive C (the hard disk ) to the diskette in
Drive A. Because all directories branch fr,om the
root directory, BACKUP copies all the files in all the
disk directories. For more information on BACKUP
