云端数据异地容灾验证方案研究
A Study Off-Site Disaster Recovery Performance of CIoud Data
摘要
Abstract
Implementation of file fault tolerance is the key to preventing data loss in cloud,especially the off-site dis-aster recovery,which can prevent large-scale power outage and natural disaster occurs from losing data.Currently disaster re-covery guarantees for multi-cloud-based storage service provider agreement.To solve these problems,we propose a remote disaster recovery capability for cloud data to validate the program———DPBDL,whose theory is to use time delay and the proofs of retrievability to check the off-site data recovery of cloud data.Then,we analysis its security and performance theo-retically and practically,and the analysis result shows that its security and be able to accurately determine the cloud data off-site disaster recovery capabilities.关键词
