About K8up

K8up is a Kubernetes operator distributed as a Helm chart and compatible with OpenShift and plain Kubernetes. It backs up persistent volume claims, runs on-demand or scheduled backups, schedules archival to long-term storage, checks repository integrity and prunes old backups. Restores use the k8up CLI.

Restic does the work underneath, so backups can go to S3-compatible storage, SFTP, REST servers or local targets. Application-aware backups capture the output of any tool that writes to stdout, and it is multi-tenant with metrics for alerting. It is a CNCF Sandbox project.

Strengths

  • Scheduled, on-demand and archival backups of PVCs
  • Many storage targets through restic
  • Application-aware backups via stdout
  • Multi-tenant with built-in metrics

Limitations

  • Requires a Kubernetes or OpenShift cluster
  • Aimed at cluster operators rather than desktop users

Software that can replace K8up for an important use case, and what changes if you switch.

  • Velero

    Backup, restore and migration tool for Kubernetes clusters.

    FreeOpen sourceLinuxSelf-hostedCommand line

    Velero backs up Kubernetes cluster resources together with volume data and can restore into a different cluster, though volume snapshots depend on the storage provider and CSI driver.

  • Longhorn

    Open-source distributed block storage for Kubernetes clusters, with replication, snapshots and backups.

    FreeOpen sourceWebSelf-hosted

    Longhorn replaces restic-based backups with its own distributed block storage for Kubernetes, adding replicated volumes, incremental snapshots, cross-cluster recovery and a web interface.
