Rancher Backup and Restore Operator backs up and restores the Rancher application running on a Kubernetes cluster. It can create a one-time backup or recurring backups by querying the Kubernetes API for selected resources, packaging them into a tar.gz file, and sending the file to configured storage. The operator preserves ownerReferences so dependencies between objects remain intact, and it can encrypt specified resources using Kubernetes Encryption at Rest configuration. Listed uses include preparing Rancher for an upgrade and restoring it after a failed upgrade, recovering Rancher to a new cluster after a disaster, and moving it between Kubernetes distributions of the same version. Storage options include S3-compatible services such as MinIO and Persistent Volumes. Installation is available through Rancher Cluster Explorer or Helm. The Rancher guide states that its procedure requires Rancher version 2.5.0 or later. This free, open-source operator is for Linux and self-hosted use. It handles Rancher application backups, not downstream cluster snapshots or Etcd backups, and user-created resources on the Rancher cluster are not backed up by default.
Who it is for
It suits teams that need to back up or restore the Rancher application on Kubernetes, including for upgrades, disaster recovery, or migration between distributions of the same version.
What is good
- Supports one-time and recurring backups
- Preserves object dependencies through ownerReferences
- Can encrypt specified resources
- Supports S3-compatible storage, including MinIO
- Can restore Rancher to a new cluster
What to know first
- Does not replace Etcd backups
- Is not a downstream cluster snapshot tool
- User-created resources are not backed up by default
- The documented procedure requires Rancher 2.5.0 or later
Verdict
The operator is a free option for Rancher application recovery, with scheduled backups and documented storage choices. Its scope is limited: it is not a cluster snapshot or Etcd backup replacement, and user-created resources are excluded by default.
