Survey on Backup and Recovery Tools and Multicluster Management Platforms in a Kubernetes

In modern IT environments, the importance of disaster recovery in providing stable services arising from system failures or data loss is emphasized. Furthermore, with the emergence of various disaster recovery tools, their selection and utilization has become a core task for stable business operations. In this study, we conducted an in-depth investigation and analysis of disaster recovery tools in the Kubernetes environment, a widely used open-source platform for application deployment and management in companies. In particular, we investigate two examples of disaster recovery tools, “Backup and Restoration tools” and “Recovery tools in Multicluster Management Platforms.” The main characteristics and differences, such as recovery support, cloud connectivity, backup location support, Role-Based Access Control support, encryption support, user interface, cost, and automatic recovery features provided by each tool, were compared, and analyzed. Based on this, we examine the importance of disaster recovery in the modern IT environment and explore optimization strategies through the integration of backup and restoration features using various tools and platforms. Our study suggests the feasibility of developing an integrated system that allows automatic recovery at both cluster and application levels. This opens the door to future research and implementation and is expected to provide even more extensive and in-depth knowledge and experience.
