Embodiment Construction

[0064] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment:

[0065] First introduce the file-level CDP protection method that the present invention proposes to support interactive data query and fast recovery:

[0066] see figure 1 The flow chart of the operation of the file-level CDP protection method supporting interactive data query and fast recovery provided by the present invention is shown. The method runs between the CDP host and the CDP server, where the following modules run on the CDP host, that is, the CDP agent and the fast recovery agent; the CDP server has the functions of metadata management and operation data storage management, and the following modules run on it , that is, an extended file tree management module, an index log module, a query module, a recovery module, and a data storage module.

[0067] Attached below figure 1 Describe in detail the flow chart of the method provided by t...

Abstract

The invention relates to the technical field of disaster recovery in computer safety, in particular to a file level continuous data protection method and a file level continuous data protection system supporting interactive data inquiry and quick recovery. The method comprises the following steps that: initialization and continuous data protection (CDP) backup are performed between a CDP host computer and a CDP server; the CDP server cooperates with the CDP host computer to quickly inquire a file system view of a protected object on any time point; the CDP server cooperates with the CDP host computer to inquire the modification record of any file in any time slot; and the CDP server cooperates with the CDP host computer to quickly recover any file set on any time point. The system comprises a CDP agent module, a quick recovery agent module, an extension file tree management module, an operation index log module, a data storage module, an inquiry module and a recovery module. Due to the adoption of the method and the system, data search efficiency during inquiry and recovery is greatly optimized and the overall performance of a continuous data protection scheme is optimized.

Description

technical field [0001] The invention relates to the technical field of disaster recovery in computer security, in particular to a file-level continuous data protection method and system supporting interactive data query and fast recovery. Background technique [0002] Today in the 21st century, the use of computers has penetrated into all aspects of our lives. Data backup has become the center of strategies including data availability, regulatory compliance, data discovery and data security risk management. Data backup technology has also become a research hotspot. [0003] Disaster recovery backup is the basic requirement for information system security to be guaranteed. The traditional disaster recovery backup method obtains data versions that are discrete in time, but the new disaster recovery method of Continuous Data Protection (CPD) can track Every operation of the user can therefore reproduce any data state of the user data during the protected period. [0004] The s...
