Problems solved by technology

The traditional stand-alone data backup and restoration system based on tape devices can no longer meet the growing business data backup needs of the radio and television industry, and does not meet the requirements of the "Information System Disaster Recovery Specification" for data disaster recovery
Therefore, the backup and security risks of such systems need to be resolved urgently.

Embodiment Construction

[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] refer to figure 1 , figure 1 A distributed data backup disaster recovery system 100 is shown, which is suitable for a local area network and includes:

[0032] The data center server 110 is used to control the operation of the system and record the status information of each device in the system.

[0033] The policy scheduling server 120 is connected to the data center server 110, generates a backup policy according to the device information recorded by the data center server 110, and performs configuration and scheduling. The backup policy generated by the policy scheduling server 120 includes the configuration of the storage unit in the media server 130 , the configuration of the backup schedule, the configuration of the valid period of data, the configuration of the backup terminal 150 and the path configuration of...

Abstract

The invention discloses a distributed data backup and disaster tolerance system and a distributed data backup and disaster tolerance method. A data central server records the state information of each piece of equipment in the system, a policy scheduling server generates a backup policy, a medium server transmits a specific backup or recovery request instruction to the policy scheduling server, and the policy scheduling server configures and schedules the medium server and tape equipment in the system for backup. By the system and the method, the scale expandability of the backup and disaster tolerance system is improved, the shortcomings of no concurrent task operations and difficulties in system expansion in the prior art are overcome, and the needs of mass data backup of the radio and TV industry can be fully satisfied.

Description

technical field [0001] The invention relates to the field of information systems, in particular to a distributed data backup disaster recovery system and method. Background technique [0002] Traditional data backup and disaster recovery methods in general industries use tape devices for systematic backup or restoration based on time points. Since the backup objects in the radio and television industry are indexed based on discrete data files, both backup and restore must be based on a single file. In addition, when performing data backup and restoration operations, due to the large amount of data, the concurrent throughput requirements of the system are very high. The traditional stand-alone tape device-based data backup and restoration system can no longer meet the growing business data backup requirements of the radio and television industry, and does not meet the requirements of the "Information System Disaster Recovery Specification" for data disaster recovery. Theref...
