Problems solved by technology
[0003] Both state backup and event backup in a distributed system can meet the requirements of high-reliability backup, but each has advantages and disadvantages. Event backup needs to back up a small amount of data and is easy to implement. However, if an event related to an event occurs, a certain In some cases, the calculation results of the active and standby boards are different
State backup backs up all the data in the database of the main board to the standby board, so that the calculation results of the main board and the standby board are completely consistent, but the backup difficulty and the amount of backup data are huge. The geometric increase in the data volume between cards may lead to the weakening of the mainboard card’s ability to process normal business, and extreme cases may cause the mainboard card to fail to work normally

Embodiment Construction
[0034] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
[0035] Such as figure 1 As shown, in an embodiment of the present invention, the data synchronization mode of the active and standby boards of the distributed system includes both the event backup mode and the state backup mode. Therefore, there are event backups and state backups in the synchronization channel. Doing two backups in one channel is to ensure the sequence of backups, that is, event backups and state backups cannot exist in the synchronization channel at the same time.
[0036] State backup and event backup, the principles of these two backup methods are different, so if you want to use them together...

The invention provides a backup method and a backup system supporting the combination of event backup and state backup. The method comprises the following steps of: dividing a backup mode adopted by an event to be backed up; and when a program receives the event to be backed up, searching for the backup mode according to the type of the event, and performing backup processing by adopting a corresponding backup mode. By the method and the system, the backup reliability of a distributed system is enhanced, the advantages of the event backup and the state backup are combined, backup data trafficis reduced, backup efficiency is improved, and the downtime of the distributed system is shortened.
Description
technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for realizing backup that support the combination of event backup and state backup. Background technique [0002] Carrier-grade or military Ethernet networks have very high requirements for network reliability. There are two common ways to improve network reliability. One is to use the redundancy of the network topology to achieve redundant backup and high reliability by changing the direction of data in the network when a single node fails. The first is by enhancing the reliability of a single node. For example, in the Ethernet equipment of the distributed system, the purpose of uninterrupted work of a single node can be achieved through the redundant backup of the active and standby boards. In order to achieve uninterrupted work of the active and standby boards, the states of the active and standby boards are synchronized in real time. There...
