摘要：【中文】本发明涉及计算机技术领域，且公开了一种用于数据存储及数据灾备的存储分层技术，一种用于数据存储及数据灾备的存储分层技术，包括：①通过储存模块将所述数据存储及数据灾备中的储存对象进行分段处理；②通过合并处理模块确定所述步骤①中分段数据是否含有相同或类似的数据块，若是，则采用预设合并规则，保留重复的数据块中的一个数据块。该用于数据存储及数据灾备的存储分层技术，通过储存模块先对数据存储及数据灾备中的储存对象进行分段处理，并通过合并处理模块对具有相同或类似的数据块进行合并产生待迁移数据，和对不具备相同或类似的数据块进行分区储存，达到简单方便分类及储存的效果。 【EN】the invention relates to the technical field of computers, and discloses a storage layering technology for data storage and data disaster recovery, which ① contains a storage module for segmenting storage objects in the data storage and data disaster recovery, a merging processing module for ② determining whether segmented data in the step ① contains the same or similar data blocks, and if so, adopting a preset merging rule to reserve one data block in repeated data blocks.

摘要：【中文】本发明涉及通信技术领域，且公开了一种窄带传输系统，包括信息采集设备、信息发射器、信息接收器和信息输出设备。该窄带传输系统及其应用方法，通过采用先整体加密，然后拆分并进行传输，再通过拼接后再解密的数据传输方法，由于对整体数据进行了加密，不但没有降低信息的安全性能力，且在数据传输过程中，加密信息区仅传输一次，既避免加密信息区多次频繁暴露在通信链路中而造成降低信息窃听和泄密隐患的情况发生，同时，又有效减轻了对窄带通信链路的传输压力，发送窗口和接收窗口均采用自适应调整模式，不但能够提高数据传输的速度，而且对于解决可靠传输和拥塞控制有非常重要的作用。 【EN】The invention relates to the technical field of communication, and discloses a narrow-band transmission system which comprises information acquisition equipment, an information transmitter, an information receiver and information output equipment. The narrow-band transmission system and the application method thereof adopt a data transmission method of firstly carrying out integral encryption, then splitting and transmitting, and then carrying out decryption after splicing, because the integral data is encrypted, the safety capability of information is not reduced, and in the data transmission process, an encrypted information area is only transmitted once, thereby avoiding the situation that the hidden danger of information interception and leakage is reduced because the encrypted information area is frequently exposed in a communication link for many times, simultaneously effectively reducing the transmission pressure of the narrow-band communication link, and a sending window and a receiving window both adopt a self-adaptive adjustment mode, thereby not only improving the speed of data transmission, but also having very important function for solving reliable transmission and congestion control.
