Data concentrated backup method, reduction method and system thereof

Abstract

The invention relates to a method to centralized backup and reduce data. It adds a process to generate and compare abstract document, and validates data correctness with irreversibility of abstract algorithm and abstract unique for one segment information.

Description

technical field [0001] The invention relates to data backup, in particular to a data centralized backup and restoration method and a backup and restoration system thereof. Background technique [0002] Since the "911" incident, the world has strengthened the construction of disaster backup systems in case of accidents. [0003] From the perspective of the realization of "disaster backup", disaster backup can be divided into two categories: one is the customer's own construction; the other is to seek professional disaster backup service companies and rent various services provided by them. Professional disaster backup service companies mainly provide the following types of backup services: [0004] 1. Provide physical space, and the customer will enter the management personnel by himself [0005] The disaster recovery service company physically provides the computer room space that meets the customer's requirements. The disaster recovery company provides all logistics servi...

[0008] 3. Rent the virtual space of the disaster recovery company

[0011] 1. The customer cannot verify the correctness of the data

In this kind of system, because the data is stored in the storage space provided by the disaster recovery service company, when the client downloads the data from the server, it is often performed when the current data is lost or damaged, so it is impossible to judge and compare The correctness of the downloaded backup data, that is, it is impossible to verify whether the downloaded backup data is the original uploaded data, and the customer is worried about the data being tampered with on the server side

[0012] 2. Similarly, for the above-mentioned worries or accusations of customers, the service provider also lacks the verification means to prove that the data it provides is the original data. When there is a disagreement between the two, it is easy to cause unnecessary contradiction

[0013] 3. In the current commonly used data backup systems, there is generally no relevant data encryption means. Therefore, the security of customer data, including confidentiality and protection from illegal theft and leakage, cannot be effectively guaranteed
