etcd is a consistent, open-source and distributed key-value store used in Kubernetes to backing all cluster resources like: configuration data, state data or metadata.
Regular backups of etcd database are crucial habit for Kubernetes clusters. Red Hat OpenShift has build-in mechanism to achieve that.
