Suppose you want to back up all the files in the \PUBLIC\SMITH directory on drive C onto a blank, formatted disk in drive A. To do so, type the following:

backup c:\public\smith\*.* a:

Suppose you need to back up all files in the \PUBLIC\SMITH directory on drive C onto a 720K floppy disk in drive B. If the floppy disk is unformatted, backup formats it before backing up any files. Because the /s switch is not specified in the following command, files in subdirectories are not backed up:

backup c:\public\smith\*.* b: /f:720k

To write a simple batch program named SMITH that supports the backup command's exit codes and the /s switch, create a file containing the following commands using any editor.

echo off

rem Smith's backup command

backup c:\public\smith\*.* b: /s

if errorlevel 4 goto error

if errorlevel 3 goto abort

if errorlevel 2 goto conflict

if errorlevel 1 goto no_files

if errorlevel 0 goto success


echo Backup stopped the process due to an error

goto exit


echo You just pressed CTRL+C to stop the backup

goto exit


echo One or more files were not backed up due to a sharing conflict

goto exit


echo Sorry, but there were no files to backup

goto exit


echo The backup was successful

goto exit


For more information about using the if command in batch programs, see the if command.
