Velero is an open-source tool designed for backup, recovery, and migration of Kubernetes cluster resources and persistent volumes. It enables users to safely back up their cluster state and restore it in case of data loss, as well as to migrate resources across clusters. Velero supports both on-premises and cloud environments, providing flexibility and reliability in managing Kubernetes workloads.
