Embodiment 1

[0024] Embodiment 1, a kind of data backup method, refer to image 3 , including the following steps:

[0025] A1. Make an identifiable mark on the received message.

[0026] The logical unit that performs this operation can be called a message distribution module, which is used to receive messages sent by other modules that need to be processed. The so-called identifiable mark is used to distinguish messages, and any method that can be recognized by the application module can be used, such as numbering, adding a time stamp, and the like.

[0027] Based on the role of distinction, the tags used need to ensure uniqueness within a certain time range, so that the tags of the messages cached in the processing module (main and backup modules) are not repeated, and an algorithm can be designed according to the needs of the actual system to ensure the tags An optional way is to use a number as a mark, the so-called number is a combination of the start time of the message distributi...

Embodiment 2

[0042] Embodiment two, a kind of data backup method, refer to Figure 4 , compared with Embodiment 1, this embodiment adds the processing of sending a response message by the active module, which is applicable to the processing situation of an application that needs to return a response. Including the following steps:

[0043] B1. Make an identifiable mark on the received message.

[0044] B2. Send the marked messages to the active module and the standby module respectively.

[0045] Figure 4 The sending to the active module is marked as B2a, and the sending to the standby module is marked as B2b.

[0046] B3a. The active module processes the received marked message.

[0047] B3b. The standby module caches the received marked message.

[0048] B4. The active module sends the data that needs to be backed up by the standby module and the tag of the corresponding message bound to the standby module.

[0049] B5a. The active module sends a response message corresponding to ...

Embodiment 3

[0053] Embodiment three, a kind of data backup method, refer to Figure 5 , compared with Embodiment 1, this embodiment adds the processing of sending a response message by the standby module, which is applicable to the application processing situation that needs to return a response. Including the following steps:

[0054] C1. Make an identifiable mark on the received message.

[0055] C2. Send the marked messages to the active module and the standby module respectively.

[0056] Figure 5 The sending to the active module is recorded as C2a, and the sending to the standby module is recorded as C2b.

[0057] C3a. The active module processes the received marked message.

[0058] C3b. The standby module caches the received marked message.

[0059] C4. The active module sends the processing result of the message and the tag binding of the corresponding message to the standby module.

[0060] In this embodiment, the processing result of the message sent by the active module ...

Abstract

A method for data backup and the corresponding application processing system. The method includes: sending a message which has first been marked to an active module and a standby module respectively; once the standby module has received the processing result and the bound mark from the active module, it deletes the message corresponding to the related mark from the buffer.

Description

technical field [0001] The invention relates to the technical field of data backup, in particular to a data backup method and an application processing system. Background technique [0002] At present, processing systems are required to have very high availability (HA: Highly Available) in many key applications, such as telecommunications systems, banking systems and billing systems, etc. These systems need to be available at any time, while ensuring response speed. In order to ensure the high availability of the system, the key modules in the system are often configured redundantly, so that when the module fails to work normally, the corresponding redundant module can take over its work and continue to provide application services. Usually, the module that works normally is called the active module, and the redundant module is called the standby module. Obviously, these two names are based on the usage status of the module. When the active module fails , the business proc...
