摘要： Transmitting filesystem changes over a network is disclosed. A hash of data comprising a chunk of directory elements comprising one or more consecutive directory elements in a set of elements sorted in a canonical order is computed at a client system. One or more directory elements comprising the chunk are sent to a remote server in the event it is determined based at least in part on the computed hash that corresponding directory elements as stored on the remote server are not identical to the directory elements comprising the chunk as stored on the client system.

摘要： A system and method are disclosed for providing efficient data storage. A plurality of data segments is received in a data stream. The system preliminarily checks in a memory having a relatively low latency whether one of the plurality of data segments may have been stored previously in a data segment repository. The memory having the relatively low latency stores data segment information. In the event that the preliminary check determines that one of the plurality of data segments may have been stored in the data segment repository, a memory having a relatively higher latency is checked to determine whether the data segment has been stored previously in the data segment repository.

摘要： Seeding replication is disclosed. One or more but not all files stored on a deduplicated storage system are selected to be replicated. One or more segments referred to by the selected one or more but not all files are determined. A data structure is created that is used to indicate that at least the one or more segments are to be replicated. In the event that an indication based at least in part on the data structure indicates that a candidate segment stored on the deduplicating storage system is to be replicated, the candidate segment is replicated.

A first anchor location j|j+1 is identified wherein a value of f(b[j−A+1 . . . j+B]) satisfies a constraint and wherein A and B are non-negative integers. A segment boundary location k|k+1 is determined wherein k is greater than minimum distance from j.

摘要： Techniques for efficiently indexing and searching similar data are described herein. According to one embodiment, in response to a query for one or more terms received from a client, a query index is accessed to retrieve a list of one or more super files. Each super file is associated with a group of similar files. Each super file includes terms and/or sequences of terms obtained from the associated group of similar files. Thereafter, the super files representing groups of similar files are presented to the client, where each of the super files includes at least one of the queried terms. Other methods and apparatuses are also described.

摘要： A network file system-based data storage system that converts random I/O requests into a piecewise sequential data structure to facilitate variable length data segment redundancy identification and elimination. For one embodiment of the invention a stateless network file system is employed. For one such embodiment, that provides multiple-client access to stored data, multiple Writes are buffered and then broken into variable length data segments. Redundant segment elimination is then effected. One embodiment of the invention allows sharing of the variable length data segments among files.
