Norton Ghost 15.0 is a rich, all-purpose backup application that's flexible enough to copy whole drives, individual files, or sets of files. Available on a bootable CD that includes Symantec's antivirus technology (so you can disinfect a system that a virus has rendered unbootable),. As a drive-backup application, Ghost 15.0 creates "images" of whole drives in the same general way that drive images are created by Windows Backup, As a file-backup app, it can save and restore copies of individual files, folders, or whole categories of files such as spreadsheets or documents. It's an elegant, lucid, and mature program that's easy enough for non-technical users, but packed with fine-grained options for advanced users, including the ability to convert backed-up images into "virtual disks" that can be run as "virtual machines" by VMware software or by Microsoft's Hyper-V technology.
