The invention relates to an anti-deletion system for SKYPEE records. The system comprises the following four modules: a human-computer interaction module, a data storage module, a data reading and WEB interface module and a SOCKET communication module. An authentication management mode is used for logging in the whole system; different characters correspond to different authorities; and users of the system are divided into two levels: administrator users and common users, wherein the administrator users are used for being responsible for managing the users, building a new CASE, and checking data, and the common users can only add, modify and delete SKYPE accounts of the CASE under the user, and check own CASE data under the user. According to the system provided by the invention, chatting information data of SKYPE texts at different places can be synchronized, the SKYPE supports login of a plurality of terminals and can simultaneously delete the data simultaneously generated by the plurality of terminals, and the data operation of each terminal is to be synchronized to the other terminal. A data recovery degree reaches 99% of an original state.
