Design and Implementation of Data Backup Encryption Device in Portable Experimental Equipment Management Terminal

In the process of experimental equipment management, data backup technology plays a key role in ensuring the normal operation of the system, improving the security of the portable teaching environment, and improving the effect of learners' experience. The application of data backup technology in the management of experimental equipment is mainly to protect all data in the system by controlling the server through the system. This paper mainly uses the experimental method and comparative method to test the data backup and recovery of college test assignments, and experiments on the experimental equipment terminal management system designed in this paper. The data results show that the response time of the system to the index and metadata access does not exceed 5s. Because of the impact of the index on the version file table, if the number of recovered files is low, the metadata processing time will be greatly accelerated.
