Velero
Velero is an open-source tool for Kubernetes backup, Disaster Recovery (DR), and workload migration across clusters and cloud providers (data protection / infrastructure operations).
- Backup and restore Kubernetes cluster resources and persistent volumes (data protection)
- DR for Kubernetes clusters, including namespace- or cluster-level restore (business continuity)
- Migration of Kubernetes workloads and data between clusters and environments (workload mobility)
- Extensible plugin model for storage providers, snapshot mechanisms, and backup locations (platform extensibility)
- CLI-driven operation with support for scheduled backups, hooks, and policy configuration (operations automation)
More About Velero
Velero is an open-source project that provides backup, DR, and migration for Kubernetes clusters (data protection / infrastructure operations). It targets the problem of protecting Kubernetes resources and associated persistent volumes so that clusters can be recovered or recreated in another environment. The project focuses on cluster-scoped and namespace-scoped Application Programming Interface (API) objects, along with persistent data stored on supported volume providers.
Velero operates by interacting with the Kubernetes API to capture and restore cluster resources (Kubernetes operations) and by integrating with underlying storage and snapshot systems to handle persistent volumes (storage management). It supports creating backups on demand or on a schedule, restoring from existing backups, and migrating workloads by backing up from one cluster and restoring to another. Backup artifacts are typically stored in object storage services configured as backup locations.
The project uses a server-side component that runs in the Kubernetes cluster and a Command-Line Interface (CLI) that administrators use to configure backup locations, schedules, and restore operations (cluster administration). Backups can include Kubernetes objects such as namespaces, deployments, services, configuration objects, and custom resources, subject to configuration. Persistent volume data can be protected either via Critical Supplier Identification (CSI) snapshots or provider-specific snapshot or file-copy mechanisms, depending on the configured plugins and storage backends.
Velero provides a plugin framework that enables support for multiple cloud and storage providers (platform extensibility). Plugins can implement backup and restore item actions, object storage backends, and volume snapshotter interfaces. This allows integration with diverse environments, including public cloud object storage and on-premises (on-prem) systems, as documented by the project. Administrators can choose providers and configure credentials and endpoints to align with organizational infrastructure policies.
For enterprise environments, Velero is used to implement policies for scheduled backups, retention, and DR drills (IT governance / resilience). Hooks enable custom pre- and post-backup actions, such as quiescing applications or running database-specific commands, which helps align backup behavior with application requirements. The tool supports multi-tenant or multi-namespace scenarios by scoping backups and restores, and it can participate in cluster migration workflows when moving between Kubernetes clusters or cloud regions.
Within a technical catalog, Velero fits under Kubernetes data protection, backup and restore, and cluster migration tooling. It directly interfaces with Kubernetes APIs, container storage interfaces, and object storage protocols where supported through plugins. Its focus on Kubernetes-native concepts and resources makes it relevant for platform engineering teams, Site Reliability Engineering (SRE) groups, and infrastructure operations staff who manage cluster lifecycle, DR strategies, and workload mobility.
