  • DETERMINING SEGMENT BOUNDARIES FOR DEDUPLICATION
    Publication number: 20150088840
    Abstract: A sequence of hashes is received. Each hash corresponds to a data chunk of data to be deduplicated. Locations of previously stored copies of the data chunks are determined, the locations determined based on the hashes. A breakpoint in the sequence of data chunks is determined based on the locations, the breakpoint forming a boundary of a segment of data chunks.

  • Data deduplication
    Patent number: 8799238
    Abstract: A method for data deduplication includes receiving a set of hashes derived from a data chunk of a set of input data chunks 310. The method includes sampling the set of hashes 320, using an index indentifying data chunk containers that hold data chunks having a hash in the set of sampled hashes 330, and loading indexes for at least one of the identified data chunk containers 340. The method includes determining which of the hashes correspond to data chunks stored in data chunk containers corresponding to the loaded indexes 350 and deciding which of the set of input data chunks should be stored based at least in part on the determination.
