Microsoft originally planned to include Windows Backup in the Home Edition as well as the Professional Edition. Unfortunately they removed it, for reasons known to themselves, from the final version. However you may install the utility from your original XP Home Edition CD or from the SP2 installation files or you can download it here.http://www.ntbackup....p-Installer.exe
Simply insert the XP CD and run NTBACKUP.MSI (it might look like just "Ntbackup") program from the folder D:\Valueadd\msft\ntbackup where D: is the letter of your CD drive. This will launch the Windows Backup Utility Installation Wizard, which will install the utility automatically. When it is finished, click "Finish."
Now you can click Start -> All Programs -> Accessories -> System Tools -> Backup, and the Backup Utility will start.
