摘要： An apparatus provides coherent data copying operations where data replication is controlled by a source storage controller directly to a destination controller and managed by a remote application. The apparatus generates a snapshot version for each source data block changed by one or more write operations to the source data block during the course of a copy operation; and copies each block of the source data to a corresponding block in the destination data in the absence of the snapshot version of the block and otherwise copying the snapshot version of the source data block to the corresponding block in the destination data.
摘要翻译：一种装置提供一致的数据复制操作，其中数据复制由源存储控制器直接控制到目的地控制器并由远程应用程序管理。该装置在复制操作过程中，通过对源数据块的一个或多个写入操作而改变的每个源数据块生成快照版本; 并且在不存在块的快照版本的情况下将源数据的每个块复制到目的地数据中的相应块，否则将源数据块的快照版本复制到目的地数据中的相应块。

摘要： Described are apparatuses and methods for remote recording of digital data. A remote server digital video recorder (RS-DVR) server system includes one or more computer readable storage devices and a digital video recorder (DVR) server. The DVR server includes an input controller, a buffer unit, and a storage controller. The input controller receives an original data stream. The buffer unit is coupled to the input controller and receives and stores at least a portion of the original data stream from the input controller. The storage controller is coupled to the buffer unit and controls direct memory access to the one or more computer readable storage devices for writing one or more subscriber data streams copied from the original data stream. Each subscriber data stream is associated with a subscriber and written to a storage device location in the one or more computer readable storage devices associated with the subscriber.
