Velero (CloudMonk.io)
Velero
Velero, formerly known as Heptio Ark, is an open-source tool designed to simplify the backup, recovery, and migration of Kubernetes cluster resources and persistent volumes. It provides a reliable and efficient way to safeguard your Kubernetes applications and their data, ensuring data protection and disaster recovery capabilities.
Key Features
* **Backup and Restore:** Velero enables you to take backups of your entire Kubernetes cluster or specific namespaces, including both Kubernetes resources (pods, deployments, services, etc.) and persistent volumes. It also supports scheduled backups and restoration from backups, allowing you to recover your cluster to a previous state in case of data loss or accidental deletion.
* **Migration:** Velero facilitates migration of Kubernetes resources and persistent volumes between clusters, making it valuable for scenarios like moving applications to a different cloud provider or upgrading your Kubernetes infrastructure.
* **Disaster Recovery:** Velero can be a crucial component of your disaster recovery strategy, providing a way to restore your applications and data in the event of a catastrophic failure.
* **Plugin Ecosystem:** Velero's plugin architecture allows for extensibility and customization, enabling integration with various storage providers and backup solutions.
Benefits
* **Data Protection:** Velero provides a robust backup and recovery solution for Kubernetes, ensuring your applications and data are protected against loss or corruption.
* **Simplified Migration:** It simplifies the migration of Kubernetes resources and persistent volumes between clusters, streamlining the process and reducing downtime.
* **Disaster Recovery:** Velero empowers you to recover your cluster from catastrophic failures, minimizing data loss and ensuring business continuity.
* **Flexibility:** Its plugin ecosystem allows for customization and integration with various storage providers and backup solutions.
Code Examples
While Velero primarily operates through its command-line interface (CLI) and Kubernetes manifests, here's a simplified example of a Backup custom resource definition:
```yaml
apiVersion: velero.io/v1
kind: Backup
metadata:
name: my-backup
spec:
includedNamespaces:
- my-namespace # Specify namespaces to include in the backup
storageLocation: my-backup-location # Name of the backup storage location
ttl: 720h0m0s # Time to live for the backup (30 days in this example)
```
This configuration defines a Backup object named "my-backup" that will back up resources within the "my-namespace" namespace to the "my-backup-location" storage location. The backup will be retained for 30 days before being automatically deleted.
