Abstract
The present invention is a method for the allocation of data on physical media by a file system that eliminates duplicate data. Efficient searches are employed using a unique algorithm when a compare on hash is used to achieve realtime operation of the file system. The in memory feature of the invention allows the search to be performed in constant time. Also, the on disk representation of search structures enables the present invention to maintain these critical search structures in a highly efficient, self-consistent and resilient manner.
