Embodiment Construction

[0019] Such as figure 2 , image 3 As shown, to build a cloud storage system, it is assumed that the system has three cloud storage servers: the first cloud storage server 1 , the second cloud storage server 2 and the third cloud storage server 3 . When administrator A uploads cloud data to a certain cloud server (the second cloud storage server 2), he needs to upload the index of the overview information of the cloud data to the second cloud storage server 2. Due to the overhead of synchronizing index information It is not large, so it can be synchronized to all servers in the cloud storage system (first cloud storage server 1, third cloud storage server 3), so that no matter where the user comes from, they can query from the nearest cloud storage server. Overview information about the data. When the user B near the first cloud storage server 1 retrieves the resource of interest according to the index of the overview information, if the first cloud storage server 1 does no...

Abstract

The invention relates to an index-based remote cloud data synchronizing method. Data occupying a larger space is stored in fewer servers in a cloud system, indexes of summarization information of all data are backed up on each server, a user judges whether cloud data summarization information which is interested by the user is stored in the system through searching the indexes, when the user needs to download resources in a cloud storage system, a server connected with the user firstly sends a synchronous request sent by the server storing the resources in the cloud system, and after synchronization is completed, the user downloads the resources from the server. According to the index-based remote cloud data synchronizing method, the cloud data in the cloud storage system is more conveniently downloaded by the user in each place, resource synchronization is blindly avoided being carried out by the cloud storage system, the quantity of the servers during cloud storage is greatly reduced, system building cost is lowered, one-point failures and property bottleneck caused by the servers in the system are reduced, data transmission links are reduced, system performance property and efficiency are improved, and efficient and stable operation of the whole system is ensured.

Description

technical field [0001] The invention relates to a data synchronization strategy in a cloud storage system, in particular to an index-based remote cloud data synchronization method, and belongs to the technical field of data storage and management in the field of cloud computing. Background technique [0002] With the rapid development of the Internet, there are more and more network applications. After entering the Internet, you can use the endless resources on various networks and various computers. [0003] If the resource server is connected to the Internet, users anywhere in the world can use relevant protocols to download resources on the server. However, when the user is far away from the resource server, the transmission time on the network will be very long. [0004] Cloud storage refers to the collection of a large number of different types of storage devices in the network through application software to work together through functions such as cluster applications...
