velero

Velero (formerly Heptio Ark) provides tools to back up and restore Kubernetes cluster resources and persistent volumes. It can run with public cloud platforms or on-premises. Key capabilities include taking backups of a cluster and restoring in case of loss, migrating cluster resources to other clusters, and replicating production clusters to development and testing clusters. Velero consists of a server that runs on the cluster and a command-line client that runs locally. The project is a Cloud Native Computing Foundation sandbox project. It supports IPv4, IPv6, and dual stack environments. The documentation provides a getting started guide and information about building from source, architecture, and extending Velero. The community welcomes participation through bi-weekly meetings, Kubernetes Slack channels, and a mailing list. The governance model describes how the project is run, including decision-making and maintainer roles. The compatibility matrix lists supported Kubernetes versions for each Velero release, with testing coverage for various combinations.
