Embodiment Construction

[0048] The present invention will be described in detail below with reference to the accompanying drawings.

[0049] In order to ensure that the key data can be recovered after being lost, the computer system of the present invention provides both a local backup and recovery strategy and a remote backup and recovery strategy connected through a network. like figure 1 As shown, it is a schematic structural diagram of the computer system of the present invention for realizing data recovery. It includes local data, local backups, and several remote backups. Local data and local backup are located in the same place, and they can be on the same server or connected through a dedicated line. Local data and remote backup are located in different places, and they are connected through the network. When data transmission occurs, the data will be automatically encrypted, consistency verification and other transmission security and data integrity verification. Both local backup and rem...

Abstract

The invention is a data backup method in computer networks, which belongs to the area of network information technology. The steps are: (1) maintain a backup files list which is dynamically updated; (2) Incremental backup information as well as related system parameters when files in the backup file list are changed, and obtain the difference information with the incremental information and original backup information; (3) bottom hide critical data selected by users; (4) encrypt data when they are remotely backup through network; (5) conduct consistency validation after the data transmission; (6) Get user's configuration for recovery; (7) judge whether system can start the data recovery; (8) conduct data recovery. Get the needed data from the original backup and incremental backup information and recover them to the corresponding paths.

Description

technical field [0001] The invention relates to a method used in the technical field of network information, in particular to a method for recovering computer network data. Background technique [0002] In today's information and networked society, computers are playing an increasingly important role in our work and life. More and more enterprises, businesses, government agencies and individuals use computers to obtain and process information, and at the same time save their most important information in the form of data files in the computer. Once a disaster of these important data occurs, it will cause an enterprise to stop functioning, and if the data is lost, an enterprise may face bankruptcy. As a result, people began to pay attention to how to ensure the integrity of data, and data backup is the only solution. [0003] The literature search of the prior art found that the Chinese patent (application) number is 200610001299.8, a patent named "data recovery method", wh...
