Abstract

The invention relates to system, method for generating an image (1999) of a data store at a past time by using a map (e.g. a time map) (1997) of the locations of data stored in the data store (1938) at the specified past time. The map allows the data storage system to quickly determine the locations of data stored in a data store at a past time, without searching the entire index (1995) of records concerning the locations of the past data.
