Abstract

A facility is provided for locating a file in a backup memory, in which each of the components forming a hierarchical pathname identifying the file is converted into a unique identity using a minimum of bytes, and in which the location of the file in backup memory is determined as a function of each such identity rather than the component names forming the hierarchical pathname.
