Problems solved by technology

[0005] However, if the CDP task is interrupted for any reason during the CDP system replication process, restoring the CDP system after the next startup requires reinitialization of the entire monitoring path. This process not only takes a long time, but also has a large amount of redundant data backup , which is a great waste of storage space and network bandwidth resources

Embodiment

[0023] The invention is based on the improvement on the original CDP backup system. Original backup system structure reference figure 2 , consists of client and console, the two are connected through Ethernet, and the transmission protocol used is TCP / IP. The 4-layer model of TCP / IP protocol is as follows: figure 1 shown. In order to realize the fast recovery function after the CDP system is interrupted on the CDP backup system, only the CDP kernel driver module and the CDP scheduling module need to be modified. The modules that cooperate with each other are all on the client side, and the whole process is transparent to the console.

[0024] like image 3 Shown, the concrete implementation process of the present invention is as follows:

[0025] 1. The CDP client needs to be installed on the host of the protected business system. At the same time, an additional host needs to be provided to install the CDP console. The client includes the CDP kernel driver module, CDP sc...

Abstract

The invention relates to a method for quickly recovering a CDP system. The CDP system is interrupted temporarily, a monitoring volume change data bit map table sectionalized by set thresholds is maintained inside a CDP core driver module; after the CDP system is restarted next time, initialized copying is performed on only the region of variation of a monitoring path according to the change data bit map table maintained by the CDP core driver module. Compared with the prior art, the method for quickly recovering the CDP system is capable of greatly reducing the initialized copied regions, removing a large amount of redundant data and quickly recovering the CDP system.

Description

technical field [0001] The invention relates to the field of data backup, in particular to a method for quickly restoring a CDP system. Background technique [0002] With the advent of the information age, today's computers have penetrated into every aspect of our lives. Most companies rely on computer systems to run their core businesses. Therefore, a large amount of data generated by the system has become the most valuable asset of the company. How to protect these Data has also become the focus of business attention. [0003] Many application fields have strict requirements on data availability and timeliness. If there is no good solution to protect these data, once a disaster occurs, the blow to the enterprise will be fatal. [0004] Now that we have entered the era of big data, the amount of data on the production system has become larger and larger. Faced with a large amount of data and a production system with high PTO (Recovery Time Objective) and PRO (Recovery Poi...
