摘要： A method of replicating a deduplicated storage system is disclosed. The method comprises storing a stream of data on an originator deduplicating system by storing deduplicated segments and information on how to reconstruct the stream of data. The method further comprises replicating the originator deduplicating system by receiving a copy of the deduplicated segments, information regarding containers for the deduplicated segments, and information on how to reconstruct the stream of data transferred from the originator deduplicating system to the replica system.

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.

摘要： A system for index searching comprises a first index, a second index, a processor, and a memory. The processor is configured to determine, using a Bloom filter for the second index of fingerprints, whether the Bloom filter indicates that an entry corresponding to a segment has been previously stored in the second index. The processor is further configured to, in the event that the Bloom filter indicates that an entry corresponding to the segment has been previously stored in the second index, retrieve a second index entry associated with the segment that has been previously stored. The memory is coupled to the processor and configured to provide the processor with instructions.

摘要： A system for storing encrypted compressed data comprises a processor and a memory. The processor is configured to determine whether an encrypted compressed segment has been previously stored. The encrypted compressed segment was determined by breaking a data stream, a data block, or a data file into one or more segments and compressing and then encrypting each of the one or more segments. The processor is further configured to store the encrypted compressed segment in the event that the encrypted compressed segment has not been previously stored. The memory is coupled to the processor and configured to provide the processor with instructions.
