  • Method for state based snapshot difference with restart capability
    Patent number: 10567542
    Abstract: A data management device includes a buffer and a processor. The processor may select an unprocessed full key and generate a buffer entry based on a difference between an entry of a local snapshot specified by the unprocessed full key and an entry of a previous local snapshot specified by the unprocessed full key. The processor may make a first determination that a lookup key entry associated with the unprocessed full key is different than a lookup key entry associated with a processed full key. The process may add the generated buffer entry to the buffer after processing the buffer in response to the first determination.
