    摘要： The method and apparatus collect file recipes from deduplicated data storage systems, the file recipes consist of a list of fingerprints of data chunks of a file. Detailed meta-data for each unique data chunk is also collected. In an offline process, research and analysis can be performed on either the meta-data itself or on a reconstruction of a full trace of meta-data constructed by matching recipe fingerprints to the corresponding meta-data. The method and system can generate the full meta-data trace efficiently in an on-line or off-line process. Typical deduplicated storage systems achieve 10× or higher deduplication rates, and the meta-data collection is faster than processing all of the original files and produces compact meta-data that is smaller to store.

    摘要翻译： 该方法和设备从重复数据删除的数据存储系统收集文件配方，文件配方由文件数据块指纹列表组成。 还收集了每个唯一数据块的详细元数据。 在离线过程中，可以对元数据本身进行研究和分析，也可以对通过将配方指纹与对应的元数据进行匹配而构建的完整的元数据轨迹进行重构。 该方法和系统可以在线或离线过程中有效地生成完整的元数据跟踪。 典型的重复数据删除存储系统实现10倍或更高的重复数据删除率，元数据收集比处理所有原始文件更快，并生成较小存储的紧凑型元数据。

    摘要： A system for directing for storage includes a processor and a memory. The processor is configured to determine a segment overlap for each of a plurality of nodes. The processor is further configured to determine a selected node of the plurality of nodes based at least in part on the segment overlap for each of the plurality of nodes and based at least in part on a selection criteria. The memory is coupled to the processor and configured to provide the processor with instructions.
