ABSTRACT:
A file system includes a plurality of servers to store file data as segments or chunks; and first data that includes file identifiers for files for which the file data are stored as segments; and second data that maps the file identifiers to the segments to which the file identifiers correspond; and location data that identifies which of the plurality of servers stores which of the segments, the location data being keyed on segment identifiers, each segment identifier being based on the data in a corresponding segment.
