Abstract: Computing device file system change detection and change replication methods and systems are described herein. In one embodiment, the change detection is accomplished by comparing two master file tables of two different versions of the same file system and inferring file system name space change, file system metadata change and file data change. The method includes creating a file system name space change log and file data change log for any objects associated with the changes to the file system. The method also includes replicating these change logs to the replication server and applying the change logs to the data store on replication server.

Abstract: Systems, methods, and media for efficient file replication are provided herein. According to some embodiments, exemplary methods may include detecting a write operation occurring within an operating system of the computing system, identifying block parameters for the write operation, as well as one or more of buffering and batching the write operation, and transmitting the write operation to a replication receiver system.

Abstract: Efficient cloud storage systems, methods, and media are provided herein. Exemplary methods may include locating a Merkle tree of a stored object on a deduplicating block store, comparing an object at a source location to the Merkle tree of the stored object, determining changed blocks for the object at a source location, and transmitting a message across a network to the deduplicating block store, the message including the change blocks and Merkle nodes that correspond to the change blocks.
