description Velero Overview
For Kubernetes environments, Velero provides open-source tools to back up and restore cluster resources and persistent data. It can protect the objects that describe an application alongside supported volume data, using storage snapshots or file-system backup mechanisms. This makes it useful when recovery requires more than simply copying files from a container.
Velero suits platform teams operating containerized applications and planning recovery from infrastructure failures or migration to another cluster. Its Kubernetes focus distinguishes it from general virtual-machine disaster recovery software. Backup storage and volume support depend on the configured providers and plugins. Restoring an application from a backup is its central recovery model, rather than continuous replication with automatic traffic failover to a secondary cloud.
help Velero FAQ
Is Velero free and who maintains it?
Velero is a free, open-source project hosted by the Cloud Native Computing Foundation (CNCF). It was originally created by Heptio, which was acquired by VMware in 2018, and is now developed by a community of contributors with governance under the CNCF umbrella.
How does Velero back up Kubernetes persistent volumes?
Velero can back up persistent volumes using either Restic-based file system snapshots or cloud-native snapshots through the CSI (Container Storage Interface). Restic works across all storage providers by copying file data at the filesystem level, while CSI snapshots are provider-specific but generally faster for large volumes.
Can Velero migrate workloads between Kubernetes clusters?
Yes, Velero supports cross-cluster migration by backing up workloads and their persistent data from one cluster and restoring them to another. Both clusters must have access to the same backup storage location, such as an S3-compatible bucket, and compatible storage classes and namespace configurations.
What is the difference between Velero and Kasten K10?
Velero is a free, CLI-driven open-source tool suitable for teams experienced with Kubernetes operations, while Kasten K10 (owned by Veeam) is a commercial enterprise platform offering a graphical UI, application-aware policies, and built-in ransomware protection. K10 provides broader application discovery and automation capabilities but requires a paid license for production deployments.
