Abstract

The CDN-based replica maintenance method is applied to a replica management server communicating with a plurality of replica storage nodes, and comprises the following steps: receiving heartbeat information of the plurality of replica storage nodes, the heartbeat information comprising battery state information of each replica storage node; identifying the states of the plurality of replica storage nodes according to the battery state information, wherein the states comprise an on-line state and an off-line state; acquiring replica information of the replica storage node in an offline state; selecting one or more replica storage nodes in an online state; and copying the corresponding copy to the selected copy storage node according to the obtained copy information needing to be copied. Theinvention also discloses a server, a replica storage node and a system. According to the method, the heartbeat information of the replica storage node is regularly received, the stability of the nodestoring the replica is monitored, the replica data of the offline replica storage node is maintained, the loss of the data replica is avoided, and an effective maintenance method is provided for replica data storage of the CDN.

Description

technical field [0001] The invention relates to the field of information storage, in particular to a CDN-based copy maintenance method, server, copy storage node and system. Background technique [0002] With the advent of big data, the growth rate of data has been increasing exponentially, and the problem of data storage has attracted more and more attention. Existing data will be copied into multiple copies and stored in servers of different stable nodes. The server has the advantages of fixed nodes and low failure rate, but at the same time affected by the site and maintenance costs, the maintenance cost of the copies has also increased significantly . Therefore, a copy storage method based on mobile terminal equipment is proposed, which uses the idle storage resources of mobile terminals to store data copies, which has the advantages of large total resources, low cost and close to users. But at the same time, there is an unstable problem in the mobile terminal equipmen...
