Abstract:
A system and method for replicating a file system. The method includes: copying a portion of the file system from a first storage, wherein the at least a portion of the file system includes underlying data and metadata, wherein the metadata includes pointers to the underlying data and metadata defining a file system hierarchy; partitioning the copied data of the file system into a plurality of blobs, wherein the plurality of blobs includes a plurality of data blobs and a plurality of metadata blobs, wherein each data blob includes at least one portion of the underlying data; generating a plurality of filter objects based on the copied data, wherein each filter object includes a list of metadata blobs; and storing the plurality of blobs and the plurality of filter objects in a second storage.
