Available as of v0.1.7

RKE clusters can be configured to automatically take snapshots of etcd. In a disaster scenario, you can restore these snapshots, which are stored on other nodes in the cluster. Snapshots are always saved locally in /opt/rke/etcd-snapshots.

Available as of v0.2.0

RKE can upload your snapshots to a S3 compatible backend.

Note: As of RKE v0.2.0, the pki.bundle.tar.gz file is no longer required because of a change in how the Kubernetes cluster state is stored.

Backing Up a Cluster

You can create one-time snapshots to back up your cluster, and you can also configure recurring snapshots.

Restoring a Cluster from Backup

You can use RKE to restore your cluster from backup.

Example Scenarios

These example scenarios for backup and restore are different based on your version of RKE.
