  • Data recovery method and device, and cloud storage system
    Patent number: 10824372
    Abstract: The embodiments of the present application disclose a data recovery method, device, and cloud storage system. A management node constructs a blank metadata database and sets the metadata database to an inaccessible state; reads backup data of configuration data and adds the backup data to the metadata database; obtains index data of data stored in the storage node and adds the index data to the metadata database; and sets the metadata database to an accessible state so as to cause the metadata database to resume service. It can be seen that, after applying the solution, when a metadata database is damaged, a metadata database is reconstructed, and the configuration data and the index data are obtained and added to the reconstructed database, realizing the recovery of the metadata.
