HI allexif,
The backup feature in Norton 360 is designed to archive copies of your personal data, such as documents and photos, so that they are preserved in the event of a catastrophic failure of your PC or hard drive. Generally, with this sort of backup, you would reinstall WIndows and your applications and then restore your data files. In order to restore your entire system without reinstalling Windows, what you want to use is an imaging program like Norton Ghost or Acronis True Image, rather than a simple file and folder backup program. An imaging program can save you a ton of work and time in recovering your system from all sorts of calamities. Both types of backup are important in order to guarantee that you do not accidentally suffer data loss.
Backing anything up to the same drive as the source data is not a good thing to do however, because if you lose that drive you lose everything, including your backups. Always backup to an external device that can be physically removed from the PC and stored in a safe place. For image backups, an external hard drive works best. For files and folders you can also use CD/DVD, USB drives or online backup.
