With Norton Ghost, users can now create backup images without restarting their computer or exiting Windows through the product's hot imaging technology. Imaging takes place in the background without interruption, allowing users to continue work on their system as the backup takes place. Users also benefit by saving valuable time and storage space with Norton Ghost's incremental backup and restore feature. Once an initial image of a hard drive is completed, users can make future backups incrementally - updating only the files and information that have changed rather than backing up the entire hard drive again. In the event it is necessary to restore data, users can choose to restore the entire system or just specific files or folders.
