WHAT IS IT ?

be used in a batch file to start your backup program when a set
percentage of the files on your hard disk have been changed.

USING BACKSTAT
BACKSTAT can be run from the DOS command line or in a batch file to
automate the process of backing up your hard disks.
Entering BACKSTAT (No Drive Letter)
will result in all of your hard drives being scanned for files that
have changed since your last backup. An information screen is then
displayed and the DOS ERRORLEVEL is set upon program termination.
Entering BACKSTAT C:
will result in DRIVE C: being scanned for files that
have changed since your last backup. An information screen is then
displayed and the DOS ERRORLEVEL is set upon program termination.
Entering BACKSTAT /F or BACKSTAT C: /F
will result in an information screen of all the files that have
changed since the last backup being displayed before program
termination.
BACKSTAT sets the DOS errorlevel from 0 to 10. This represents
the percentage of files that have changed since the last backup.
If more than 10% of the files have been changed, the errorlevel
will be set to 10. Run BACKSTAT from a batch file as follows:
BACKUP.BAT
------------------------------------------------------------------------------
ECHO OFF
BACKSTAT %1
IF ERRORLEVEL 10 GOTO BACKUP
IF ERRORLEVEL 9 GOTO BACKUP
IF ERRORLEVEL 8 GOTO BACKUP
IF ERRORLEVEL 7 GOTO BACKUP
IF ERRORLEVEL 6 GOTO BACKUP
IF ERRORLEVEL 5 GOTO CONTINUE
IF ERRORLEVEL 4 GOTO CONTINUE
IF ERRORLEVEL 3 GOTO CONTINUE
IF ERRORLEVEL 2 GOTO CONTINUE
IF ERRORLEVEL 1 GOTO CONTINUE
IF ERRORLEVEL 0 GOTO CONTINUE
:BACKUP
<enter the name of your backup software here>
GOTO END
:CONTINUE
ECHO Backup of the hard drive in not needed at this time
:END
