    • Data management systems, data management system storage devices, articles of manufacture, and data management methods are described. According to one embodiment, a data management system includes a plurality of storage devices individually comprising a physical storage space, wherein the physical storage space of one of the storage devices is configured to store a baseline version of a data object and the physical storage space of an other of the storage devices is configured to store a delta version of the data object and processing circuitry configured to control storage operations of at least one of the storage devices, to process a restore request with respect to the data object, to access the delta version from the other of the storage devices responsive to the restore request, and to initiate communication of data of the baseline version and the delta version of the data object to a computer system.

    • A tape mirror interface comprises an input terminal coupled to at least one input node and capable of receiving data transfer requests, a plurality of output terminals coupled to a plurality of tape storage devices, and a control element coupled to the input terminal and plurality of output terminals. The control element presents the plurality of tape storage devices as separate media devices and selectively controls data transfer in a synchronous mode and a split mode. In the synchronous mode, writes to a target tape storage media are mirrored to a mirrored tape storage media. In the split mode, writes are written to tape storage devices independently.
    • 磁带镜接口包括耦合到至少一个输入节点并且能够接收数据传送请求的输入端,耦合到多个磁带存储装置的多个输出终端以及耦合到输入端和多个输出的控制元件 终端。 控制元件将多个磁带存储设备呈现为单独的媒体设备,并且以同步模式和分离模式选择性地控制数据传输。 在同步模式下,对目标磁带存储介质的写入镜像到镜像磁带存储介质。 在分割模式下,写入将独立写入磁带存储设备。
