Problems solved by technology

[0005] 2. Disasters caused by man-made causes;
[0020] This method mainly uses backup software to realize backup and tape management. Its disadvantages are obvious. Because tapes are used to store data, data recovery is slow, and data in the backup window will be lost. The real-time performance is relatively poor, so it is difficult to guarantee Continuous operation of business systems

Embodiment 1

[0064] see figure 1 , which is a schematic structural diagram of the disaster recovery system of this embodiment. As shown in the figure, the disaster recovery system includes the following parts:

[0065] A. The centralized control management unit S100 adopts cluster management, adopts centralized management for local clusters and remote clusters, and conducts overall monitoring of local backup, remote replication, and recovery in the event of a disaster. The operation information is analyzed and processed in time, and at the same time, the initial configuration and condition setting of each management unit are performed when the system disaster recovery device is initially installed.

[0066] This unit can automatically or manually switch the faulty site to an available site. At the same time, it can also issue upload comparison and upload commands, that is, to compare whether the data in each site is consistent with the data in the data storage management unit. If inconsis...

Embodiment 2

[0113] see image 3 , which is a schematic diagram of the implementation scheme of the disaster recovery system of this embodiment, image 3 yes Figure 4 A special case of , where there is only one backup site, the following is for image 3 The workflow of the disaster recovery system will be described (each management center in this figure refers to the server where the corresponding management unit is located). The system includes: centralized control management center S300; production site S301; standby site S302; remote storage and forwarding management center S303; data storage management center (main) S304; data storage management center (standby) S305.

[0114] The centralized control management center S300 mainly monitors the entire disaster recovery system, issues relevant configuration operations, and receives information reported by each management unit forwarded by the remote store-and-forward management center S303.

[0115] When a disaster occurs, the central...

Embodiment 3

[0124] see Figure 4 , this figure shows a schematic diagram of the implementation of the disaster recovery system of this embodiment, which includes: a centralized control management center S400, a production site S401, a backup site 1S402, a backup site NS403, a remote storage and forwarding management center (master) S404, Remote store and forward management center (standby) S405, data storage management center (main) S406, data storage management center (standby) S407.

[0125] This figure is a schematic diagram of another embodiment of the disaster recovery system of the present invention, and its working principle is the same as image 3 The disaster recovery system with only one backup site is basically the same and will not be repeated.

[0126] Here is just a supplementary explanation. For multiple backup sites, the priority of the backup sites can be set in the centralized control management center S400 (automatically generated by default, and can also be manually m...

Abstract

The invention discloses a disaster tolerance system and a disaster tolerance method thereof. The method comprises the following steps: (1) a data backup management unit carries out local backup on data of a current production site, records the sequence of the backup data and tests the reliability thereof; (2) a remote store-and-forward management unit carries out remote replication and storage on the backup data; (3) the remote store-and-forward management unit tests the reliability of the backup data, maps the backup data into a date storage management unit to be stored after success, and simultaneously transmits the backup data into each standby production site; and (4) when the production site suffers catastrophic failures, the disaster tolerance management unit starts the standby production site, and carries out the fast recovery of data. The disaster tolerance system of the invention adopts a distributed disaster tolerance system structure: network service system disaster tolerance and network storage system disaster tolerance, and integrates a network security mechanism with a network disaster tolerance mechanism; and the entire system has strong system protection and disaster tolerance capability, and improves the service quality thereof.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a disaster recovery system and a disaster recovery method thereof. Background technique [0002] As information becomes an increasingly important corporate asset, many companies are committed to minimizing the risk of downtime (downtime refers to a machine that stops running or is abnormally shut down and cannot work normally, which is often referred to as a crash phenomenon) and avoids business interruption. potential impact. [0003] At present, the main causes of catastrophic problems in the system are as follows: [0004] 1. System resource failure, including hardware failure and software failure; [0005] 2. Disasters caused by man-made causes; [0006] 3. Disasters caused by natural causes, such as shipwrecks, hurricanes, and earthquakes. [0007] Businesses often rely on back-office and manual processes to keep the business running until systems are resto...
