Embodiment Construction

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

[0049] In order to ensure that key data can be recovered after loss, 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. As shown in FIG. 1 , 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. The local data and the local backup are located in the same place, and they can be located on the same server or connected through a dedicated line. The 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, verified for consistency, and verified for transmission security and data integrity. Both local backup and ...

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 field of network information technology, in particular to a method for restoring 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, merchants, 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 occurs to these important data, 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 the data, and data backup is the only solution. [0003] After searching the literature of the prior art, it is found that the Chinese patent (application) number is 200610001299.8, and the patent named "...
