Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] like figure 1 As shown, the data backup system of the present invention is built on a unified layered structure, and each layer includes: an application layer, a service layer, a presentation layer, an abstraction layer, and a physical layer. The lower layer provides corresponding services for the upper layer above it. The physical layer is a variety of disk arrays and tape libraries provided by various hardware manufacturers. The part of the system that interacts with the physical layer hardware is the abstraction layer. This layer performs different driver designs through the storage devices of different hardware manufacturers, and uses the command sets provided by each Based on it, it provides a unified command interface for data backup and status query. In the implementation, the data backup function is supported by the FC protocol, so through this layer, the ...

Abstract

The present invention discloses a data backup system utilizing layered structure to realize data high usability and safeness. System is divided 5 layers, which are application layer, service layer, presentation layer, abstraction layer, and physical layer. Said Physical layer is every hard ware manufacturer provided different kinds of disk arrays and tape library; abstraction layer interaction with physical layer in system, said layer to proceed different driving design through different hard ware manufacturer storage facility; presentation layer corresponding uses command with different hardware unit provided command and information, capable of extension else storage facility; service layer providing user visualization data backup system; application layer providing required application system to satisfy different trade industry operational properties. Said system is a high efficiency, high reliability data backup system, having network long-distance backing up, real time backing up, fast backing up and timing backing up function.

Description

technical field [0001] The invention belongs to the technical field of data backup, and in particular relates to a data backup system which utilizes a layered structure to realize high availability and safety of data. Background technique [0002] In the current enterprise-level applications, many systems require 7×24 hours of uninterrupted work, but there are unforeseen circumstances, natural disasters, computer system failures, human errors, etc. will cause damage to the system, and the loss of data will bring great harm to the enterprise. cause huge losses. In addition, with the continuous development of information technology, people's demand for various data information is also increasing. When we use data, we always hope that the content of the data is reliable and correct, but it affects the operation of the data. It is inevitable to affect the correctness of the data, even destroy the data, and cause all or part of the data to be lost. Therefore, the current applica...
