A way to backup your files (Windows XP)

Backing up files is a vital part of using IT. Unfortunately, backing up files is boring and potentially time consuming. This solution was arrived at after evaluating about 4-5 freeware, shareware and commercial alternatives.

Criteria

  • Low cost
  • Can handle backup over the network
  • Automatic operation
  • Email notification of success or failure
  • Set and forget

Components

The backup solution uses:

  • ntbackup – the free backup solution provided with win XP
  • a .bat (or batch) file
  • the Windows scheduler
  • Blat command line mailer (http://www.blat.net/)

Solution

The key to the solution is the following .bat file. It is pretty much self documenting. The batch file is called either:

For full backup

backup.bat normal

For differential backup

backup.bat differential

Text of backup.bat

setlocal

REM – blat is installed and available
REM you have created an ntbackup saved selections file for your selections .bks
