Abstract: A backup and recovery system for a computer deals with the creation and subsequent incremental updating of an image copy of the data. This image copy is stored on a separate storage device (“backup storage device”) also connected to the computer system. By storing the image data on the backup storage device in a format that is directly usable by the operating system/file system on the user's computer, the invention gives the user access to a complete and up-to-date copy of their computer storage device, including all data stored therein such as that in the form of user files, applications, preferences, system files, partition tables, hidden partitions, and free space. In the event of failure of the computer system storage device, or loss or corruption of the data therein, the invention provides for the restoration of the data through an image- or file-copy of the contents of the backup storage device.
