  • Systems and methods for organizing and mapping data
    Patent number: 7363316
    Abstract: A system and method is provided for organizing and mapping data. In exemplary embodiments, a copy of at least one first data block created from a first computing device is generated. A copy of one or more second data blocks created from one or more second computing devices utilizing the copy of the at least one first data block is also generated. The copy of the at least one first data block is related to the copy of the one or more second data blocks in a branching data structure. The copy of the at least one first data block and the copy of the one or more second data blocks is mapped to a storage medium via an index associated with the branching data structure.
