KubeSphere Backup vs Retour

KubeSphere Backup is a cloud disaster-recovery service for hybrid-cloud Kubernetes environments. It backs up and recovers data across clusters, clouds, and Kubernetes versions, and supports different Kubernetes distributions and S3-standard object storage. CSI snapshot backup covers stateful applications such as MySQL, MongoDB, and Redis. Users create and run data-protection tasks through a web console without needing expertise in Kubernetes backup tools such as Velero. Listed uses include recovery from hardware or system failures, configuration errors, and improper operations, as well as multi-cluster protection and moving application data between clouds. The free plan covers 2 protected applications, 3 days of retention, and a 10 GB hosted repository. Basic costs $65 a month and includes 100 protected applications, 14 days of retention, and 100 GB of hosted repository. Direct cluster connection requires the Kubernetes API server address in kubeconfig to be reachable over the public network; agent connection is an alternative. The repository access domain must be compatible with AWS S3 standards. For Copy Volumes backups, the vendor advises disconnecting the database beforehand to preserve data consistency and integrity.
