    • Systems and methods for single instance storage operations are provided. Systems constructed in accordance with the principals of the present invention may process data containing a payload and associated metadata. Often, chunks of data are copied to traditional archive storage wherein some or all of the chunk, including the payload and associated metadata are copied to the physical archive storage medium. In some embodiments, chunks of data are designated for storage in single instance storage devices. The system may remove the encapsulation from the chunk and may copy the chunk payload to a single instance storage device. The single instance storage device may return a signature or other identifier for items copied from the chunk payload. The metadata associated with the chunk may be maintained in separate storage and may track the association between the logical identifiers and the signatures for the individual items of the chunk payload which may be generated by the single instance storage device.
    • 提供了单实例存储操作的系统和方法。 根据本发明的原理构造的系统可以处理包含有效载荷和相关联的元数据的数据。 通常,将数据块复制到传统存档存储器中,其中包括有效载荷和关联的元数据的块中的一些或所有块被复制到物理存档存储介质。 在一些实施例中,数据块被指定用于存储在单个实例存储设备中。 系统可以从块中移除封装,并且可以将块有效载荷复制到单个实例存储设备。 单个实例存储设备可以返回从块有效载荷复制的项目的签名或其他标识符。 与块相关联的元数据可以被保持在单独的存储器中,并且可以跟踪逻辑标识符与单个实例存储设备可以生成的块有效载荷的各个项目的签名之间的关联。
