Abstract

The invention discloses a data distributed storage method and system which includes acquiring performance parameters of all storage nodes, determining the priority of the storage nodes according to the performance parameters of the storage nodes and the corresponding preset weights, and storing data blocks finishing data block division and coding into the storage nodes with high priority. The method and system is used for collecting various performance parameters of the storage nodes to serve as the basis of follow-up data block storage, completely considers the performance of the storage nodes and well guarantees data reliability.

Description

technical field [0001] The present invention relates to environmental data storage technology, in particular to a data distributed storage method and system based on Erasure Code encoding. Background technique [0002] With the development of cloud environment data center technology, more and more business applications rely on the elastic resource support capabilities provided by the cloud environment to implement the deployment of their application logic and the storage of business data. In order to improve the reliability of data, data backup has become one of the primary problems that cloud data centers must solve. The traditional data backup is to copy the complete copy of the data to different storage nodes, so as to improve the reliability of the data. However, this method needs to occupy a large amount of storage space, which is not conducive to the reasonable allocation of storage resources. In addition, the complete data copy process also takes a long time. [000...
