Exemplary embodiments provide methods, mediums, and systems for replicating metafiles between a source and a destination. The metafile may be subdivided into blocks. The contents of the metafile may be transferred by locating the blocks which are changed between the source version of the metafile and the destination version of the metafile. The changed blocks may be examined to retrieve the contents of the changed blocks. The records in the changed blocks may be evaluated to determine whether to create a corresponding record at the destination, delete a corresponding record at the destination, or update a corresponding record at the destination. Accordingly, the metafile may be replicated in a logical manner, by transferring only changed records rather than the entirety of a changed block. Moreover, the transfer is conducted efficiently because unchanged blocks are eliminated from consideration at the outset.
