With the development of 5G, the coming of the world of everything interconnection, the development of the application of information technologies such as "cloud, moving, physical, big, intelligent" and the like, digital archives of various industries are growing explosively, for example: the public security, the inspection hospital, the law institute and other institutions form the historical records with different forms of characters, charts, audios, videos and the like with value in the legal investigation of the legal case, the illegal crime treatment and the implementation of security management, and the historical records are the basis and the summary of office work and law enforcement of all levels of functional unit departments. These archives are important information resources for serving societies and civilians.
IDC predicted that the global data circle (with the data circle representing the data set created, collected, or replicated each year) would increase from 32ZB in 2018 to 175ZB in 2025, an increase of over 5 times. The Chinese data circle is accelerated most rapidly, in 2018, the proportion of the Chinese data circle to the global data circle is 23.4%, namely 7.6ZB, and is expected to increase to 48.6ZB in 2025, and the Chinese data circle accounts for 27.8% of the global data circle, and the Chinese data circle becomes the largest data circle in the world.
