摘要： Providing a subset of de-duplicated as output is disclosed. In some embodiments, the output includes a subset of data stored in de-duplicated form in a plurality of containers each of which includes a plurality of data segments. For each container that includes one or more data segments included in the subset, a corresponding container data is included in the output. Each container may include one or more segments not included in the subset. For each container the corresponding container data of which is included in the output, a corresponding value in a data structure that includes for each container stored on the de-duplicated storage system a data value indicating whether or not the corresponding container data has been included in the output is updated.
摘要翻译：提供一个被重复输出的子集作为输出。在一些实施例中，输出包括在多个容器中以重复形式存储的数据的子集，每个容器中的每一个包括多个数据段。对于包含子集中包含的一个或多个数据段的每个容器，相应的容器数据被包括在输出中。每个容器可以包括不包括在子集中的一个或多个段。对于包含在输出中的相应的容器数据的每个容器，数据结构中的相应值包括存储在去重复存储系统上的每个容器的数据值，该数据值指示对应的容器数据是否已被包括在输出更新。

摘要： A system for backup replication comprises a processor and a memory. The processor is configured to determine data present in a most recent backup not present in a previous backup; transmit an extent specification; and transmit data segment fingerprints of the one or more data segments. The memory is coupled to the processor and is configured to provide the processor with instructions.

摘要： Transmitting filesystem changes over a network is disclosed. A hash of data comprising a chunk of directory elements comprising one or more consecutive directory elements in a set of elements sorted in a canonical order is computed at a client system. One or more directory elements comprising the chunk are sent to a remote server in the event it is determined based at least in part on the computed hash that corresponding directory elements as stored on the remote server are not identical to the directory elements comprising the chunk as stored on the client system.
