Data storage system and method based on multi-cloud architecture

Abstract

The invention discloses a data storage system and method based on a multi-cloud architecture. The system comprises a user access layer, a storage management layer, a storage management layer and a data transmission layer. The user access layer is used for carrying out identity authentication and realizing safe access; the storage management layer is used for integrating API interfaces provided by different cloud service providers to form a unified virtual cloud disk operation interface; the data service layer is used for dynamically segmenting file data and storing meta-information of the file data in a local database after segmentation; and the data transmission layer is used for carrying out block encryption on the file data and uploading the file database to a corresponding cloud end in a block manner based on a load balancing algorithm. The file data can be uploaded to the cloud after being encrypted, the security of the data is guaranteed, and the meta-information of the file data is stored in the local database, so that the control right of the local database on the file data is guaranteed, and the security of the data is further guaranteed.

Description

technical field [0001] The present invention relates to the technical field of data security storage, in particular to a data storage system and method based on a multi-cloud architecture. Background technique [0002] In the public cloud environment, data is stored in a third-party cloud service provider, and data security is guaranteed by the cloud service provider. The transparency of its security services brings users distrust of cloud storage security. Users compress and encrypt files in the process of uploading and downloading, which is cumbersome and inefficient, and the usability is poor. The private cloud method is complex to build and expensive, and is not suitable for small and medium-sized enterprise organizations. Therefore, the existing technical solution fails to effectively guarantee the reliability and integrity of the data when the data is stored. [0003] Therefore, the prior art still needs to be improved and improved. Contents of the invention [00...
