The Windows 7 Backup and Restore center has a few new features compared to versions past. Especially of note is the ability to create a system image – a snapshot in time of your entire hard drive. This is especially useful for when you have your computer working well with all of your applications installed and configured just the way you like. Should your hard drive die, you can load up the image and restore the entire system just as it was when the image was taken.
Using a combination of image based and file based backups is recommended. For example, take an image based backup after you finish configuring your computer or making any major changes. Then, perform regular file based backups until you make another significant change. Should you lose your hard drive, you can restore the point in time image and then restore any files that have been updated since the last image was taken.
This article will show you how to perform an image based backup as well as how to perform a restore from your image.
