DATA CLOUD STORAGE METHODS, CLIENT TERMINAL AND DATA STORAGE SERVER

摘要

A data cloud storage system, client terminal, storage server and application method, wherein the data storage method includes: sending a storage server query request to a scheduling management service center; receiving and caching first address information when the scheduling management service center is under normal operation, and selecting first address information from the cached first address information; sending a resource request to a storage server corresponding to the first address information; such that the storage server allocates a storage unit for the target data and generates storage resource information; sending a data storage request to the storage server, such that the storage server generates data index information based on attribute information of the target data, and storing the target data in the storage unit allocated to the target data. The embodiments of the present application can guarantee data storage, query and downloading in the event of a failure of the scheduling management service center. Thus, the sensitivity of the data cloud storage system to the failure of the scheduling management service center is reduced.
