Back up your applications with Veeam Kasten

Introduction

Veeam Kasten K10 is a backup and restore solution specifically designed for Kubernetes environments. In Cloud Temple's Managed Kubernetes product, Kasten is integrated to allow you to protect your applications, restore data when needed, and ensure business continuity.

This tutorial will guide you through the basic steps to back up and restore an application using Kasten.

Prerequisites

Before you begin, ensure you have the following:

  • An active Managed Kubernetes cluster.
  • Your cluster ID (e.g., ctodev).
  • An application deployed in your cluster that you want to back up.

1. Access the Kasten Dashboard

The Kasten dashboard is accessible via a secure URL, constructed from your cluster's identifier.

  1. Construct the access URL : The URL is based on the following template: https://k10.external-secured.<identifiant>.mk.ms-cloud-temple.com/k10/ Replace <identifiant> with your cluster's identifier. For example, if your identifier is ctodev, the URL will be: https://k10.external-secured.ctodev.mk.ms-cloud-temple.com/k10/.

  2. Access the URL in your browser.

    :::info Security Note Access to this URL is restricted to the public IP addresses you have registered. If you are unable to log in, ensure your IP address is authorized by contacting Cloud Temple support. :::

:::tip[Built-in Quick Start Guide ] The Kasten console includes an interactive quick start guide on its home page. Feel free to follow it for a first-time setup directly from the interface. :::

2. Understanding Backup Storage

By default, Kasten is preconfigured to use Cloud Temple's object storage (S3) service to securely and durably store your backups.

No configuration is required. The storage location is already configured in the Kasten dashboard, under Settings > Locations. This configuration ensures that your data is stored on a sovereign infrastructure.

:::info[Pricing Model ] The Veeam Kasten service is included in the Managed Kubernetes product. Backup storage on our sovereign S3 is billed based on usage. Refer to our pricing table for more details. :::

3. Create a Backup Policy

A backup policy (Policy) is a set of rules that define when and how to back up your applications.

:::warning[Politique de sauvegarde existante ] A backup policy named infra-backups is already configured in your Kasten instance. This policy backs up the essential components delivered with the cluster.

Do not modify or delete this policy.

You must create your own policies to back up the applications you deploy. :::

  1. In the Kasten dashboard, go to the Policies section and click Create New Policy.

  2. Name your policy: Provide a descriptive name, for example backup-my-app-daily.

  3. Define the frequency (Action):

    • Action: Snapshot (instantané).
    • Frequency: Choose the frequency that suits you (for example, Daily at 02:00).
  4. Select the resources to back up:

    • Select resources by: You can select applications by name (Application Name), by namespace (Namespace), or by labels.
    • To back up all applications in a namespace, select Namespace and choose the desired namespace.
  5. Click Create Policy to save.

The policy will run automatically at the defined frequency. You can also trigger a manual run by clicking the "Play" (▶️) button next to the policy.

4. Restore an Application

Kasten facilitates restoring an application to its previous state from a restore point.

  1. In the dashboard, go to the Applications section. You will see the list of your applications and their compliance status with respect to backup policies.

  2. Select the application you want to restore.

  3. Choose a restore point: The application page displays a list of available restore points. Choose the one you want to use and click Restore.

  4. Configure the restore:

    • You can choose to restore to a new namespace or replace the existing application. For this tutorial, we will replace the existing application.
    • Click Restore to start the process.

Kasten will now restore the application to the state captured in the snapshot. You can track the progress in the dashboard.

5. Backup Security

Protecting your backup data is a priority. The integration of Kasten into the Managed Kubernetes product adheres to the highest security standards.

  • Encryption : In compliance with SecNumCloud requirements, all your backups are encrypted. Data is encrypted in transit to S3 storage using the TLS 1.3 protocol and at rest in storage buckets using the AES-256 algorithm.

  • Permission Management : Access to the Kasten interface and its features is controlled by a permissions system based on Kubernetes RBAC. Only authorized users can create, modify, or execute backup and restore policies, ensuring strict governance of your backup operations.

Conclusion

You have learned how to use Veeam Kasten to perform basic backup and restore operations in your Managed Kubernetes cluster. Kasten offers many advanced features, such as application migration between clusters and granular retention policies, which you can explore to strengthen your data protection strategy.
