Abstract
In a digital data processing system having an on-line file system component, a method and apparatus for archiving the contents of a selected client volume stored on the file system. The archiving is performed automatically, beginning with an initial duplication of the existing contents of the client volume into an archive volume, then continuing as changes, including additions, deletions and modifications, are made to the files comprising the client volume. Older, previously-archived versions of modified files are gracefully discarded so as to moderate the rate of growth of the archive volume. The archive volume may be used to restore the client volume, either selectively or in whole, in the event of inadvertent damage to, or loss of, files in the client volume.
