Abstract
Official abstract text for this publication.
A method and apparatus for backing up a computer system. A backup is provided of a data stored on a first computer by the first computer generating a dump stream. The dump stream is transmitted to a second computer, the second computer uses the dump stream to maintain a file system copy of the data. One or more snapshots of the file system of the second computer are stored on a backup computer, the snapshots providing a backup of the data stored on the first computer.
