Velero (software) provides backup, restore, and migration capabilities for Kubernetes clusters and cloud computing storage by orchestrating snapshot and object-store operations. Originally developed by Heptio and later maintained by VMware and a broad open-source community, Velero integrates with Amazon Web Services, Google Cloud Platform, and Microsoft Azure ecosystems to protect cluster state and persistent storage. It is used by infrastructure teams, platform engineers, and site reliability engineers working with containerized workloads and container orchestration platforms.

Overview

Velero emerged from efforts at Heptio to address disaster recovery and data portability for Kubernetes users, and was part of projects discussed at conferences such as KubeCon and CloudNativeCon. The project moved under the stewardship of VMware while attracting contributions from organizations like AWS, Google, Microsoft, and many independent contributors. It focuses on coordinating backups of etcd-derived cluster metadata and persistent volume data stored in object stores provided by cloud vendors and third-party solutions.

Features

Velero implements incremental and scheduled backups, point-in-time restores, and cluster migration tooling that integrates with cloud provider snapshot technologies and object storage. It supports application-consistent backup patterns used by teams familiar with GitOps workflows and integrates with continuous delivery systems discussed at KubeCon and used by companies like Red Hat and HashiCorp. Features include backup hooks for pre- and post-processing, label- and namespace-scoped selection, restore transformation capabilities, and dry-run validation commonly found in Cloud Native Computing Foundation-hosted projects.

Architecture and Components

Velero's architecture comprises a server-side controller running within a Kubernetes cluster and a client CLI used by platform operators. Core components include a controller deployment, a RESTful API server, and plugins for provider-specific operations used in interactions with Amazon EBS, Google Compute Engine, Azure Disk Storage, and S3-compatible object stores like MinIO. The system leverages etcd data exported via the Kubernetes API, and coordinates with CSI drivers defined by the Container Storage Interface specification. Plugin interfaces allow integrations with ecosystems such as Prometheus for monitoring and Grafana for visualization.

Use Cases and Deployment

Common use cases include disaster recovery planning used by enterprise teams at IBM and cloud-native adopters like Spotify, cross-cluster migrations promoted by multi-cloud strategies at Netflix-scale organizations, and development/test environment cloning in companies employing Continuous Integration pipelines. Deployments range from single-cluster backups storing snapshots in Amazon S3, to multi-cluster migration workflows leveraging Google Cloud Storage or Azure Blob Storage, and on-premises object stores such as Ceph or MinIO for regulated industries including healthcare and finance. Operators deploy Velero via Helm charts and Kubernetes manifests at scale in private data centers and public cloud regions.

Development and Community

The project is developed in Go (programming language) with a contributor base spanning cloud providers, independent developers, and vendor-backed engineers. Roadmaps and issues are discussed in public repositories and at community forums, contributor summits, and sessions at KubeCon and other Cloud Native Computing Foundation-affiliated events. Key corporate contributors historically include VMware, Heptio, Amazon Web Services, Microsoft, and Google, while maintainers collaborate with SIGs and working groups across the Kubernetes ecosystem.

Security and Compliance

Velero interacts with cloud provider IAM roles and service accounts, requiring careful configuration of permissions in AWS Identity and Access Management, Google Cloud IAM, or Azure Active Directory to follow least-privilege principles endorsed by security teams at organizations like CIS and NIST-aligned auditors. It supports encryption for backup data at rest using provider-managed keys such as AWS KMS and Google Cloud KMS, and can be combined with enterprise key management solutions used by regulated firms. Security reviews and advisory disclosures are handled publicly through issue trackers and security mailing lists.

Adoption and Performance

Adoption spans startups to large enterprises, with public case studies and talks from platform engineers at VMware, Google, Amazon Web Services, and other adopters highlighting operational scenarios. Performance characteristics depend on object-store throughput, snapshot speed of block storage services like Amazon EBS or Azure Disk, and Kubernetes API server scalability influenced by etcd cluster size. Benchmarks often compare Velero workflows to vendor-specific snapshot tools and migration frameworks used by organizations migrating workloads between regions or clouds.
