Problems solved by technology

[0006] 1 The stand-alone version realizes file backup locally, so it is not limited by network bandwidth, low cost, and fast backup speed; but the disadvantage is that once the local system fails, the backup data cannot be restored
The traditional server / client mode system management operation is complicated, which affects the efficiency of backup
[0009] Aiming at the above-mentioned problem of complex file backup operation in server / client mode, the present invention proposes a file online backup method

Embodiment Construction

[0061] The main module that the inventive method relates to has: client module, management system module and server module three parts, refer to figure 1 . Wherein, the client module, that is, the backup agent, is composed of a user interface submodule and a service processing submodule. The user interface sub-module includes six functional modules: login interface, main interface, system setting, file backup, file recovery and task management. Utilizing JSP and AJAX technologies, the present invention implements a browser-based user interface sub-module. The service processing sub-module is responsible for performing the above operations in the background to realize file upload, file download, file monitoring and file analysis.

[0062] The server module consists of a Web server and a storage server. The web server provides the business logic processing of the system for the backup agent and the management system. Storage servers are used to organize, store and manage dat...

Abstract

The invention relates to a file online backup method. The traditional backup method is complex in operation and has low backup efficiency. The method disclosed by the invention comprises a file backup stage and a file recovery stage, wherein during backup, a user file is partitioned by a backup agent, and the sub-block data are sent to a storage server through a network. During recovery, the backup agent downloads the original backup data to the specified directory of a local host from the storage sever through the network. By the method, the backup is selected according to the type of the file, selective backup of the file of the specific type is realized, a multi-task backup mode is realized at the same time, and multiple folders can be independently backed up.

Description

technical field [0001] The invention relates to the field of file backup, in particular to an online file backup method. Background technique [0002] File backup is a common method used to increase data availability and ensure data integrity. Existing computer data backup methods can be divided into hardware-level backup and software-level backup. [0003] Hardware-level backup refers to the use of redundant hardware to ensure the continuous operation of the system, such as hard disk duplexing, dual-machine fault tolerance, etc. If a piece of hardware is damaged, the redundant hardware can immediately take over its work. However, this method has high hardware costs and cannot prevent logical errors, such as human misoperation, viruses, and data errors. When a logical error occurs, the hardware backup will only copy the error once, and cannot really protect the data. The function of the hardware backup can only ensure that the system can continue to run when a failure occu...
