Problems solved by technology

[0004] In the traditional application system, after the system fails, the snapshot of the system will not continue to be used, so there is a risk of data loss
At present, in the application system with multiple controllers such as dual controllers or eight controllers, the general processing method is to map the data volume to be snapshotted under each controller, and then, when it is necessary to take a snapshot, run The normal controller performs snapshot command processing. This processing method makes the business processing logic more cumbersome, and the ID of the snapshot is prone to confusion, and in the maintenance of the snapshot, confusion is prone to occur, resulting in data inconsistency

Abstract

The invention discloses a multi-controller snapshot processing method, which is applied to an application system with two or more controllers, including: according to the snapshot relationship of each controller established in advance, respectively setting the snapshot relationship of each controller The configuration file is saved in the corresponding controller; among them, the ID of the corresponding controller is set in the configuration file; the working status of each controller is monitored in real time. The saved configuration file is transferred to another normal controller; a snapshot volume is created under the normal controller, and the snapshot relationship of the abnormal controller is mapped to the created snapshot volume according to the transferred configuration file. Through the technical solution provided by the invention, fault-tolerant processing of snapshot processing under multiple controllers is realized, thereby ensuring data consistency and security.

Description

technical field [0001] The invention relates to disaster recovery technology of computer cloud storage, in particular to a multi-controller snapshot processing method and device. Background technique [0002] With the rapid development of computer technology, digital information has gradually replaced paper media data, showing an average daily exponential growth. Massive data has led to the development of cloud computing, big data and mass storage systems, and the demand for storage devices and storage applications is also increasing. Government industries, banking systems, and power companies have high requirements for data security and business continuity, and online data protection must be provided. Snapshot is an effective method for online storage devices to prevent data loss. In more and more high-end storage systems, snapshot has become a basic and indispensable technology. [0003] The main function of the snapshot is to back up and restore online data on demand. ...
