Abstract

The invention relates to a cloud storage data storage and retrieval method, device and system, belonging to the technical field of cloud storage safety. The data storage method comprises the following steps: grouping source data to be stored according to a preset grouping policy; restructuring the content of the source data by taking the groups as units to form new data; and transmitting the new data to a cloud storage data center for storage. The data retrieval method comprises the following steps: retrieving the accessed data from the cloud storage data center according to an access request; acquiring data restoring information corresponding to the accessed data; and restoring the accessed data into the source data according to the data restoring information. The invention also provides the cloud storage data storage and retrieval device and system. The invention greatly improves the safety of data stored in the cloud storage data center and greatly reduces the possible loss for users caused by data leakage.

Description

technical field [0001] The invention belongs to the technical field of cloud storage security, and in particular relates to a method, device and system for storing and retrieving data in cloud storage. Background technique [0002] Data has been proven to be one of the important assets of enterprises, and the rapid growth of data has made enterprises face unprecedented challenges. At the same time, the rapidly changing world economic situation and the cost pressure brought about by fierce competition make enterprises have to consider how to reduce IT costs to meet the growing storage requirements of enterprises. [0003] The existing storage architecture can be divided into two types: one is a proprietary architecture, such as DAS (direct attached storage, direct attached storage), SAN (Storage Area Network, storage area network) and network access storage server (Network access server, NAS), etc. This type of storage system is exclusively used by one party, which can prov...
