Blockchain-based Disaster Recovery Data Storage and Security Auditing Solution in Multi-cloud Environment
Bin Liu, Yang Xin, Suhuan Dai · 2022
The utilization of cloud disaster recovery services has emerged as the current trend in data disaster recovery research and application due to the quick growth of virtualization technology and cloud applications. Single-cloud disaster recovery services fall short of users’ demands for data security backup due to technical flaws, managerial weaknesses, network attacks, natural calamities, etc. To implement cross-cloud disaster recovery and multi-cloud data storage, disaster recovery systems must be deployed in multi-cloud and heterogeneous cloud settings. To do this, problems with distributed cross-cloud storage’s data batch audit and problem resolution must also be resolved. In this paper, we propose a blockchain-based distributed storage and security audit solution for disaster recovery data in a multi-cloud environment, which addresses the issues of multi-copy storage management and security audit of multi-cloud data.
