Backup--Examples

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

:error

echo Backup stopped the process due to an error

goto exit

:abort

echo You just pressed CTRL+C to stop the backup

goto exit

:conflict

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

goto exit

:no_files

echo Sorry, but there were no files to backup

goto exit

:success

echo The backup was successful

goto exit

:exit
