I was asked to create a script that would be an easy double click backup solution for sales people who are on the road. The following is a batch file that will do a differential backup of which ever folder you specify in the script. You only need to change the destination drive and source. It will look for a full backup, if one isn’t found, it will do one and do differential backups there after.
@echo off
:Variables – Change drive letter to match your backup drive
set destdrive=F:
set source=C:\Documents and Settings\cpratt
:You shouldn’t need to change any of these
set destination=%destdrive%\Backup
set server=%computername%
set textlogpath=%destdrive%\Backup\%computername%-Backup.txt
set archivepath=%destdrive%\Backup\OldLogs
:Set Time
for /F “tokens=1-4 delims=/ ” %%i in (‘date /t’) do (
set Month=%%j
set Day=%%k
set Year=%%l
set Date=%%j-%%k-%%l
set dirdate=%%j%%k%%l
)
for /f “Tokens=1-2 delims=/ ” %%i in (‘time /t’) do (
set tm=%%i
set ampm=%%j
)
