摘要： 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.

摘要： A system and method for efficiently restoring one or more data containers is provided. A common persistent consistency point image (PCPI) is identified between a source and a destination storage systems prior to the destination storage system performing a rollback operation to the commonly identified PCPI. Differential data is then transmitted from the source storage system in a line efficient manner to the destination storage system.

摘要： An embodiment of the invention provides an apparatus and method for presenting differences in a file system of a clustered storage system. In an embodiment, the clustered storage system receives a request from a host, where the request is for a listing of changes in the file system within a time interval. A comparison unit in each storage node of the clustered storage system determines each metadata container associated with the file system which has changed within the time interval. The application programming interface buffers at least one identifier that corresponds to a metadata container associated with the file system which has changed within the time interval. The application programming interface packages and transmits the at least one identifier to the host. The at least one identifier is readable on the host.
