Configuring Backups for an Azure Kubernetes Service Cluster

You can configure backups for an Azure Kubernetes Service (AKS) cluster.

Prepare for the Guided Setup

• Verify that the cluster is running a supported distribution and release.

• Validate your Kubernetes environment.

Start the Guided Setup

1. From the Command Center navigation pane, go to Protect > Kubernetes.

   The Kubernetes applications page appears.

2. In the upper-right area of the page, click Add cluster.

   The How should we deploy this backup? page appears.

3. Select Azure AKS.

4. Click Next.

   The Cloud Storage page of the guided setup appears.

Cloud Storage

To review the supported combinations of primary and secondary storage, see Metallic Storage Options.

Primary Copy

1. For the primary copy of the backup data, select existing cloud storage or create new cloud storage.

   Steps to create cloud storage for the primary copy

   1. Click the add button .

      The Add cloud storage dialog box appears.

   2. From Type, select the storage provider, and then enter the necessary values.

      Storage provider	Values
      Metallic Recovery Reserve	Region: Select the region for the cloud storage.
      Microsoft Azure Storage	Name: Enter a descriptive name for the cloud storage. Credentials: Select existing credentials or create new credentials. Region: Select the region for the cloud storage. Container: Enter the name of the container. For example, enter bucket_name.

   3. Click Save.

2. Click Next.

   The Plan page of the guided setup appears.

Secondary Copy

1. Decide whether to store a secondary copy of the backup data for long-term retention.

   Steps to create cloud storage for a secondary copy

   1. Click the add button .

      The Add cloud storage dialog box appears.

   2. From Type, select the storage provider, and then enter the necessary values.

      Storage provider	Values
      Metallic Recovery Reserve	Storage class: Select the storage class for the type of access that you want to have for the data. Region: Select the region for the cloud storage.
      Microsoft Azure Storage	Name: Enter a descriptive name for the cloud storage. Credentials: Select existing credentials or create new credentials. Region: Select the region for the cloud storage. Container: Enter the name of the container. For example, enter bucket_name.

   3. Click Save.

2. Click Next.

   The Plan page of the guided setup appears.

Plan

A plan specifies the storage to back up the data to and other settings such as recovery point objective (RPO) settings.

1. Select an existing plan or create a new plan.

   Steps to create a plan

   1. Click the add button .

      The Add plan dialog box appears.

   2. In the Plan name box, enter a descriptive name for the plan.

   3. For the plan settings, select pre-defined settings or create custom settings:

      • To select pre-defined settings, under Retention rules, select one if the following:

        • Select Standard retention to retain the incremental backups for 1 month.

        • Select Extended retention for optimized storage where the incremental backups of primary and secondary copies are retained for 1 month, and extended retention for monthly and yearly full backups.

          Note: The Extended retention option is available only when the secondary copy backup is selected.

      • To create custom settings, select Custom plan, and then specify the following:

        • For Retention, specify the amount of time to retain the primary copy.

        • For Retention (secondary copy), specify the amount of time to retain the secondary copy.

        • For Backups run every, specify how often to run backups.

   4. Click Done.

2. Click Next.

   The Add Cluster page of the guided setup appears.

Add Cluster

Add your AKS cluster.

1. In the Kubernetes API server box, enter the API server URL and port number in the following format:

   https://servername:port

   To get the URL, run the following command:

   kubectl cluster-info

   In the following example output, the Kubernetes control plane is running at https://k8s-123-4.your.domain:6443, so you would enter https://k8s-123-4.your.domain:6443 in the Kubernetes API server box.

   If your control plane is running on port 443, you don't have to include the port number.

   Kubernetes control plane is running at https://k8s-123-4.your.domain:6443
   
   CoreDNS is running at https://k8s-123-4.your.domain:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

2. In Name, enter a descriptive name for the cluster.

3. For Authentication Type, leave Service account selected.

4. In Service account, enter the name of a service account to access the cluster for backups and other operations.

5. In Service token, enter the service account token.

6. If you want to verify that you selected the correct backup gateways and server plan for the cluster, click the Previous button.

   After you click Next, you the Metallic software adds the cluster, and you can't change the backup gateways or server plan until after you complete the configuration wizard.

7. Click Next.

   The Metallic software adds the cluster. To view the cluster, go to Protect > Kubernetes.

   The Add Application Group page appears.

Add Application Group

1. In Application group name, enter a descriptive name for the application group.

2. Browse for and then select the applications to back up.

3. Click Next.

   The Summary page of the guided setup appears.
