Abstract:

The paper traces the evolution of a segment based file system. The final system is typical of the virtual memory systems found in large general purpose time-sharing systems. The contents of the file system is a collection of symbolically named segments organized in a hierarchial structure. The user directly references segments in the file system. All movement of information between the different levels of physical memory is done automatically by the system using paging. Complete privacy of user information is guaranteed, although controlled sharing is possible. The system includes file backup facilities to protect users from information loss due to system failure.
