摘要
A computer-enabled method of storing an input dataset in a storage medium includes storing a copy for each of a plurality of repeatable blocks of data in an input dataset in a storage medium. The process further includes finding a location in the storage medium of the copy of a block of data in the input dataset. Finding the location includes determining a most likely location in the storage medium of the copy of the block of data from one or more blocks of data preceding the block of data based on statistics of past stored data. Finding the location further includes if the determined most likely location contains a block of data that matches with the actual block of data, retrieving the location in the storage medium of the copy of the block of data. The process also includes storing the location of the copy of the block of data.
