Abstract

The embodiment of the present invention discloses a data recovery method, device, and cloud storage system. The management node constructs a blank metadata database, and sets the metadata database to an inaccessible state; reads the backup data of the configuration data, and stores the The backup data is added to the metadata database; the index data of the data stored in the storage node is obtained, and the index data is added to the metadata database; the metadata database is set to be accessible state to bring the metadata database back into service. It can be seen that, with this solution, when the metadata database is damaged, the metadata database is rebuilt, and the configuration data and index data are obtained, and the obtained configuration data and index data are added to the new database constructed, realizing the Data recovery.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a data recovery method, device and cloud storage system. Background technique [0002] With the continuous development of technology, cloud storage systems have been widely used. Cloud storage system refers to a system that integrates various types of storage devices in the network through application software to work together through functions such as cluster applications, network technology, or distributed file systems, and can provide users with data storage and business access functions. . The application of cloud storage system can satisfy users to access data conveniently at any time and any place. [0003] An existing cloud storage system may include a management node (CVM, Cloud Video Management), a video access node (CVA, Cloud Video Access) and a storage node (CVS, Cloud Video Storage). Among them, the management node mainly provides management services...
