The invention discloses an Internet business operation process backtracking method, system and device. The method comprises the following steps: S1, collecting data, collecting behavior data generatedby a user in the business system operation process, and interactive data responded by a business system server; S2, generating an analog file, generating a front-end behavior instruction file according to the behavior data, and generating a business data source file according to the interaction data; S3, providing a simulation service, monitoring the front-end behavior instruction file to carry out front-end simulation, and monitoring the business data source file to carry out server simulation; and S4, generating a backtracking video, backtracking and recording the operation process of the user according to the front-end simulation and the server simulation, and generating the backtracking video. According to the invention, the reproduction and backtracking of the user operation businessbehavior are realized, the communication between the business service provider and the user and the evidence storage of the related operation process are facilitated, and the ambiguity and dispute between the business service provider and the user are avoided.
