1. Windows XP Pro has a back-up utility installed - click
Start ->
All Programs ->
Accessories ->
System Tools ->
Backup.
2. If you have Windows XP Home edition then you need to install it:
* Insert the Windows XP CD and if it doesn't start double click it in Windows Explorer
* Once you see the welcome scree click
Perform Additional Tasks then
Brose this CD.
* Navigate to the ValueAdd folder, then open Msft, and finally Ntbackup.
* Double click
Ntbackup.msi - this will install the back-up utility on your computer.
3. Now that you have the back-up utility installed let me show you how to use it:
Click
Start ->
All Programs ->
Accessories ->
System Tools ->
Backup.
This will start the back-up wizard which is pretty straight-forward, you only need to chose the files/folders you want to automatically back up, then choose the back-up storage device (this could be a second hard drive, external hard drive etc), then you have to choose the time interval and schedule the backup.
