A public and private hybrid distributed cloud storage system and a cloud storage method. The cloud storage system includes an application system, a segmentation aggregation system, a public storage system and a private storage system. The application system is configured to provide original complete data and initiate an access request to the segmentation aggregation system. The segmentation aggregation system is configured for dividing the original complete data into a number of data fragments, and distributing said data fragments to said public storage system and private storage system according to a preset storage proportion and also receiving the data fragments returned by the public and private storage systems and aggregating them into the complete data, and then transferring to said application system. The public storage system is configured to manage, authenticate and store data fragments. The private system is configured to manage, authenticate, count, control and store data fragments. The method is based on the cloud storage system and consists of the steps of logging data and reading data. This invention gives solution to problems that the private storage system has limited capacity and inadequate bandwidth and the public storage system is vulnerable in security. |
