| Abstract: | Cloud storage service, as a cloud computing derivative product, intending for mass data storage networks, provides an effective solution. While saving storage costs and system resources, the system is required to provide a complete backup, disaster recovery data center, to ensure data security, fault tolerance and efficient storage functions. At present, cloud disaster recovery models are restricted to limited network location, using virtualization technology and relying on the local server implementations. Different from traditional cloud disaster recovery models, a DHT-based cloud disaster recovery model is described in this paper, applicable to WAN universal data-level disaster recovery model. |
