Velero Is an Open Source Tool to Back Up and Migrate Kubernetes Clusters

Backups can capture subsets of the cluster’s resources, filtering by namespace, resource type, and/or label selector, providing a high degree of flexibility around what’s backed up and restored. Users of managed Kubernetes offerings often do not have access to the underlying etcd database, so direct backups/restores of it are not possible. Resources exposed through aggregated API servers can easily be backed up and restored even if they’re stored in a separate etcd database.
