  <Notice type='warning'>

  When the protected applications exceed the subscription quota, you can upgrade your subscription to get more quota of protected applications, or you can delete some backup jobs and recovery jobs to release some quota. Please upgrade your subscription or release some quotas to prevent the data already backed up from any potential data loss.

  </Notice>

## Change of subscription

After you subscribe to a plan, you can change it according to your needs, and the billing will be based on the new subscription. The billing formula is described as follows:

Amount paid = Amount payable of new subscription － (Amount payable of current subscription/Days of current subscription) x (Days of current subscription － Used days of current subscription)


<Notice type='note'>

Duration of the new subscription must be equal to or longer than that of the current subscription. For example, if your current subscription is charged on a quarterly basis, then the new subscription must be charged on a quarterly or yearly basis.

</Notice>

## Renewal

The Service currently supports renewal of the same subscription or upgrading to a higher-level subscription. Renewal to a lower-level subscription is not supported.
## Out of credit

The Service will send you a notice starting from 7 days before your subscription expires. You can click **Subscribe Now** to renew your subscription. If you do not renew your subscription in time, the Service will still provide services to ensure business continuity, but the quota on backup, recovery, and hosted storage repository will be changed to the quota of the free plan. 

If the current protected applications exceed the quota of the free plan, the excessive protected applications will be deleted after a certain period of time (the actual time varies according to different subscriptions).

Billing


This topic introduces the basic concepts of KubeSphere Backup.

## Namespace

A namespace is an abstract of a set of resources and objects. You can create multiple namespaces to achieve isolation between applications in different namespaces. The Service charges for namespaces.

## Source cluster

A source cluster is the source Kubernetes cluster associated with a backup plan.
## Protected application

The number of protected applications refers to the number of applications (namespaces) protected in the executed backup jobs and recovery jobs. For example, if you back up one application every day, then 30 protected applications will be generated in 30 days. You can delete backup jobs to release the quota of protected applications.
## Retention

Retention is the period when an application is protected, which varies according to different subscriptions.

     2. If the agent connection component is not running properly, run the following command to check the logs for further troubleshooting.
   
        ```bash
        kubectl logs -l app=agent -n kubesphere-cloud-system
        ```
   
        ![](/images/docs/disaster-recovery-and-backup/import-cluster/agent-logs.png)
   
   - Step 2:
   
     1. If the component cannot run properly, run the command shown on the page to uninstall the component.
   
     2. Run the command shown on the page to install the agent connection component again.
   
     3. After the component is successfully installed, click **Connect** to establish the agent connection.

## Obtain kubeconfig

### Managed Kubernetes clusters

If you use managed Kubernetes cluster service from cloud providers, use the kubeconfig exposed to the public network to import your cluster. For example:

- If you use Alibaba Cloud Container Service for Kubernetes (ACK):
  - Make sure you select the **Expose API Server with EIP** for **Access to API Server**. For more information, see [Alibaba Cloud documentation](https://www.alibabacloud.com/help/en/container-service-for-kubernetes/latest/getting-started-with-ack-using-the-ack-console#section-ll1-v66-lz8).
  - On the **Cluster Information** page, click the **Connection Information** tab and you can find the kubeconfig under **Public Access**. For more information, see [Alibaba Cloud documentation](https://www.alibabacloud.com/help/en/container-service-for-kubernetes/latest/use-the-kubernetes-api).
- If you use Cloud Container Engine (CCE) of Huawei Cloud:
  - Make sure you have bound EIP for **Public API Server Address** on the **Cluster Details** page, and download the kubeconfig from the **Kubectl** tab. For more information, see [Huawei Cloud documentation](https://support.huaweicloud.com/intl/en-us/usermanual-cce/cce_01_0107.html#section2).
- If you use Tencent Kubernetes Engine (TKE):
  - Make sure you have enabled **Internet access** on the **Cluster APIServer information** page, and copy or download the kubeconfig. For more information, see [Tencent Cloud documentation](https://intl.cloud.tencent.com/document/product/457/30639#configuring-kubeconfig).

### Self-managed Kubernetes clusters

If you use self-managed Kubernetes clusters, run the command `cat $HOME/.kube/config` to obtain the kubeconfig for importing the cluster. Make sure the address of <code>cluster.server</code> is exposed to the public network, or select **Skip TLS verification** at the same time to import the cluster.

If you cannot import the cluster, please take the following steps to obtain the kubeconfig again:

1. On every control plane of the Kubernetes cluster, go to the directory `/etc/kubernetes/pki/` and use the [sample file](https://github.com/stoneshi-yunify/scripts/blob/master/update-apiserver-with-external-ip.sh) to create a script file. 

2. Run the following command to make the script file executable:

   ```bash
   chmod +x <script file name>
   ```

3. Run the following command to run the script on every control plane of the cluster:

   ```bash
   ./<script file name> <public IP address>
   ```

4. Forward the private IP address and port of the control plane to a public IP address and port. 

5. Run the following command on the control plane to obtain the kubeconfig:

   ```bash
   cat $HOME/.kube/config
   ```

6. Replace the address of <code>cluster.server</code> with the public IP address and port, and use the modified kubeconfig to import the cluster.

### No Kubernetes cluster deployed

1. Run the following command to download the latest version of KubeKey:

   ```
   curl -sfL https://get-kk.kubesphere.io | VERSION=v2.2.2 sh -
   ```

   <Notice type='note'>

   - It is recommended that you [use KubeKey to deploy a Kubernetes cluster](https://github.com/kubesphere/kubekey#advanced).

   - If your network connection to GitHub is slow, run the command `export KKZONE=cn` first before downloading KubeKey.

   </Notice>

2. Run the following command to create a sample configuration file, and refer to [Edit the configuration file](https://kubesphere.com.cn/en/docs/installing-on-linux/introduction/multioverview/#2-edit-the-configuration-file-of-a-kubernetes-multi-node-cluster) to edit the configuration file for your cluster.

   ```bash
   ./kk create config [--with-kubernetes version] [(-f | --file) path]
   ```

3. In the configuration file of the cluster (for example, `config-sample.yaml`), add the following content under `spec.kubernetes`:

   ```yaml
   apiserverCertExtraSans: <[public IP address]>
   ```

   <Notice type='note'>

   Make sure you indent 2 spaces at the beginning of the line.

   </Notice>

4. Run the following command to create the cluster:

   ```bash
   ./kk create cluster -f config-sample.yaml
   ```

   <Notice type='note'>

   Make sure you replace `config-sample.yaml` with your configuration file name.

   </Notice>

5. Forward the private IP address and port of the control plane to a public IP address and port.

6. Run the following command on the control plane to obtain the kubeconfig:

   ```bash
   cat $HOME/.kube/config
   ```

7. Replace the address of <code>cluster.server</code> with the public IP address and port, and use the modified kubeconfig to import the cluster.

   * To view the usage records of the protected applications of the backup plan, go to the **Overview** page and click **Usage Records** in **Subscription**.

   </Notice>

## View and create a volume snapshot class

If you select **Use CSI Snapshot** when creating a backup plan, you have to ensure the associated volume snapshot class exists in your Kubernetes cluster. To view or create a volume snapshot class, refer to the following steps.

### View a volume snapshot class

If you already have a volume snapshot class, refer to the following steps:

1. Run the following command to view the PVCs in the namespace to be backed up. In the output, you can see the storage class associated with each PVC.

   ```bash
   $ kubectl get pvc -n <namespace>
   NAME             STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS     AGE
   busybox-test-a   Bound    pvc-5f0e74b8-d8d0-4c68-a3f8-5cd125a4d45a   10Gi       RWO            csi-hostpath-a   24h
   ```

2. Run the following command to view the information about a specified storage class. In the output, you can see the `PROVISIONER` associated with the storage class. 

   ```bash
   $ kubectl get sc csi-hostpath-a
   NAME                        PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
   csi-hostpath-a              hostpath.csi.k8s.io-a   Delete          Immediate           true                   24h
   ```

   <Notice type='note'>

   Make sure you replace the `csi-hostpath-a` with the actual name of the storage class in your cluster.

   </Notice>

3. Run the following command to view the volume snapshot class. If any volume snapshot class exists in your cluster, you have to ensure that the `PROVISIONER` obtained in previous steps supports the existing volume snapshot class before making any snapshot of the PVCs. If no volume snapshot class exists in your cluster, perform the following steps to create one.

   ```bash
   $ kubectl get volumesnapshotclass --show-labels
   No resources found in tt namespace.
   ```

### Create a volume snapshot class

If you want to create a volume snapshot class, refer to the following steps:

1. Use the following content to create a YAML file, for example, `volumesnapshotclass.yaml`.

   ```yaml
   apiVersion: snapshot.storage.k8s.io/v1 # Set this field according to the snapshot CRD version of your cluster. The service currently supports v1 and v1beta1.
   deletionPolicy: Retain # Must set to Retain.
   driver: hostpath.csi.k8s.io-a # Consistent with the PROVISIONER of the storage class in your cluster.
   kind: VolumeSnapshotClass
   metadata:
     name: csi-hostpath-sc # Set to any value accepted by Kubernetes.
     labels:
       velero.io/csi-volumesnapshot-class: 'true' # Must set this label.
   parameters: # (Optional) set this field according to your actual storage system.
     ...
   ```

2. Run the following command to create the volume snapshot class.

   ```bash
   kubectl apply -f volumesnapshotclass.yaml
   ```

3. Run the following command to view the volume snapshot class. Make sure the value of `DRIVER` in the output is consistent with the value of `PROVISIONER` associated with the storage class.

   ```bash
   $ kubectl get volumesnapshotclass --show-labels
   NAME                     DRIVER                  DELETIONPOLICY   AGE   LABELS
   csi-hostpath-sc          hostpath.csi.k8s.io-a   Retain           9s    velero.io/csi-volumesnapshot-class=true
   ```

### Notes

When using a volume snapshot class, you have to note that:

- If PVCs created by CSI and other PVCs not created by CSI both exist in the namespace to be backed up, select **Copy Volumes** to back up your PVCs.

- If PVCs created by multiple CSI drivers exist in the namespace to be backed up, perform the above steps to create a corresponding volume snapshot class for each CSI driver.

- If multiple volume snapshot classes exist for the same CSI driver, the service will randomly select a volume snapshot class for backup. 

- When creating a recovery plan, make sure the target cluster can access the volume snapshot backup.

## Create and manage resource templates
### Create a resource template

When creating a backup plan, you can create a resource template so that you can reuse it. To create a template, refer to the following steps.

1. In the **Backup Resources** area on the **Create Backup Plan** page, click **Resource Template** > **Create Resource Template**.

2. In the **Create Resource Template** dialog box that is displayed, set the template name.

   <Notice type='note'>

   **App Resources** and **Cluster Resources** are supported. By default, **App Resources** is enabled. If you need to back up cluster-level resources or both namespace-level and cluster-level resources, enable **Cluster Resources**. Here, **App Resources** is used as an example.

   </Notice>

3. In the **Select App** area, specify one or more source namespaces to back up by name or label.

4. In the **Filter Resources** area, filter application resources by **Group** and **Resource**, and click **OK**.

   <Notice type='note'>

   - If you do not filter application resources, all resources in the namespace will be selected.
   - If you have enabled **Cluster Resources**, but do not filter cluster resources, no cluster-level resources will be selected.

   </Notice>

5. In the **Create Resource Template** area, select the created template from the drop-down list.

6. To edit the template, click <img src="/images/console/icon-edit.svg" width="15" /> next to the template from the drop-down list. On the **Edit Resource Template** page, change the resource template information as needed, and click **OK**.

### View and manage resource templates

To view and manage all backup resource templates, please refer to the following steps.

1. On the **Backup Plans** tab, click **Resource Templates**.

2. In the **My Templates** dialog box that is displayed, you can view all templates.

3. Click a template. On the upper-right corner of the page, you can apply, edit, and delete the template.

   <Notice type='note'>

   You can also click **Create Template** on the left side of the page to create a template.

- [Can I delete a backup/recovery job in progress?](#can-i-delete-a-backup/recovery-job-in-progress?)

## Why my cluster is not ready when creating a backup/recovery plan?

- After you import a cluster, it will take about 5 minutes to install backup and recovery components on the cluster. The actual installation speed is dependent on the network speed. The cluster remains as not ready until the components are up and running.
- If the kubeconfig used for connecting the cluster is invalid, the cluster is not ready.

## Do I need to buy a S3-compatible storage repository from QingCloud?

No. You just need to ensure the object storage repository to be added is compatible with AWS S3 Standard and accessible to the internet.

## What resources will be covered in a backup?

A backup covers all the resources and other data selected by you for backup in the source namespace, including workloads, projects, user permissions, and persistent data.

## Can I execute multiple backup/recovery jobs associated with the same cluster at the same time?

No. You can execute multiple backup/recovery jobs associated with the same cluster, but they can only be executed once at a time in sequence.

## Why certain resources have recovery errors when source Kubernetes cluster version is different from target cluster version?

Errors may occur when the resource (Kubernetes built-in objects or CRDs) versions in the source cluster is different from the target cluster. Please ensure that the resource versions in the source cluster are compatible with the target cluster.

## Why the status of recovery job remains in progress during execution?

The Service does not support storage class detection for now. If the target cluster does not have the storage class backed up by the backup job associated with the recovery job, the persistent volume created through the storage class in the source cluster in the target cluster will remain in `pending` status, which causes the recovery job remains in progress. Please check the storage class in the target cluster when creating a recovery plan.

## Can I back up multiple namespaces at once?

Not supported for now and will be available in the future.

## Can I back up cluster-level resources?

Not supported for now and will be available in the future.

## Can I create CSI volume snapshots?

Yes. You have to ensure that your Kubernetes cluster has the appropriate volume snapshot class. For more information, see [Create volume snapshot class](../quickstart/create-backup-plan/#create-volume-snapshot-class).

## Can I back up/recover KubeSphere multi-cluster projects and applications?

Not supported for now and will be available in the future.

## Where are the resources and data in the cluster stored after backup?

If you use a hosted repository, resources and data will be stored in the cloud storage repository in QingCloud. If you use a S3-compatible repository, resources and data will be stored in the storage repository you added.

## Can I select multiple source namespaces when creating a backup plan?

Not supported for now and will be available in the future.

## Can I delete multiple backup jobs at once?

Not supported for now and will be available in the future. If you need to delete multiple backup jobs, you can delete the backup plan to delete all the backup jobs under the backup plan.

## Can I delete a backup/recovery job in progress?

Not supported.

FAQs


After you import a Kubernetes cluster, a namespace `qiming-backend` will be created on the cluster for installing backup and recovery components, including Velero installer and Velero itself.

This document describes how to troubleshoot issues related to KubeSphere Backup.

## Kubernetes cluster resource request

To let backup and recovery components run smoothly, make sure your Kubernetes cluster has enough resource requests. The default resource settings are described as follows:

1. The Velero installer is a DaemonSet named `restic` that controls the transmission of local files to an S3 storage repository. Its resource request is as follows:

   ```yaml
   name: restic
   resources:
     limits:
       cpu: "1"
       memory: 1Gi
     requests:
       cpu: 500m
       memory: 512Mi
   ```

   <Notice type='note'>

   The default settings are recommended. To change the resource settings, run `kubectl edit daemonset restic -n qiming-backend`,  modify the settings under `spec.template.spec.containers.resources`, and save your changes.

   </Notice>

2. Velero is a 1-replica Deployment that handles the control logic of Velero, including backup and recovery. Its resource request is as follows:

   ```yaml
   name: velero
   resources:
     limits:
       cpu: "1"
       memory: 1000Mi
     requests:
       cpu: 500m
       memory: 256Mi
   ```

   <Notice type='note'>

   The default settings are recommended. To change the resource settings, run `kubectl edit deploy velero -n qiming-backend`, modify the settings under `spec.template.spec.containers.resources`, and save your changes.

   </Notice>

## Obtain the component logs

If the backup and recovery components do not run properly, please try to obtain the logs of relevant pods for troubleshooting.

1. On the control plane of your cluster, run the following command to obtain the information of pods running in the `qiming-backend` namespace.

   ```bash
   $ kubectl get pods -n qiming-backend
   NAME                                READY   STATUS    RESTARTS   AGE
   restic-98lc4                        1/1     Running   0          80m
   velero-564c9df5c6-mn2s7             1/1     Running   0          80m
   velero-installer-66d65557c4-dz86t   1/1     Running   0          83m
   ```

2. Run the following command to obtain the logs of Velero pods.

   ```bash
   kubectl logs <Velero pod ID> -n qiming-backend > /tmp/velero.log
   ```

3. Run the following command to obtain the logs of the `restic` pods.

   ```bash
   kubectl logs <restic pod ID> -n qiming-backend > /tmp/restic.log
   ```

## Obtain backup and recovery information and logs

If any backup job or recovery job is not running properly, please obtain the information and logs of the abnormal job for troubleshooting.

### Prerequisites

1. Make sure your machine can access the cluster with an error reported.

2. Download the installation package for Velero v1.7.0 according to your environment from [this page](https://github.com/vmware-tanzu/velero/releases/tag/v1.7.0).

3. Run the following command to unzip the installation package and view the version information.

   ```bash
   tar -xvf <installation package filename>
   cd <installation package directory>
   chmod +x velero
   ./velero version
   ```

4. Run the following command to create a configuration file and edit it.

   ```bash
   mkdir -p $HOME/.config/velero
   vi $HOME/.config/velero/config.json
   ```

5. Enter the following content in the configuration file to link the configuration file to the `qiming-backend` namespace. Save the changes when you finish.

   ```json
   {
     "namespace": "qiming-backend"
   }
   ```
   
6. Save the kubeconfig of the cluster for troubleshooting to `~/.kube/config`. By default, Velero uses this kubeconfig to connect to the cluster. You can also use `velero --kubeconfig=<your-kubeconfig-file>` to specify the path of the kubeconfig.

### Obtain information and logs of a backup job

1. Run the following command to view the information of backup jobs.

   ```bash
   ./velero get backups
   ```

2. Run the following command to view the details of backup jobs.

   ```bash
   ./velero describe backup <backup job name>
   ```

3. Run the following command to view the logs of backup jobs.

   ```bash
   ./velero backup logs <backup job name>
   ```

### Obtain information and logs of a recovery job

1. Run the following command to view the information of recovery jobs.

   ```bash
   ./velero get restores
   ```

2. Run the following command to view the details of recovery jobs.

   ```bash
   ./velero describe restore <recovery job name>
   ```

3. Run the following command to view the logs of recovery jobs.

   ```bash
   ./velero restore logs <recovery job name>
   ```

## Troubleshooting for components installation

-  A pod cannot start running in the `qiming-backend` namespace.

  1. Run the following command to view the causes of start failure.

     ```bash
     kubectl -n qiming-backend describe pod <pod name>
     ```

  2. If the output shows error in pulling images, run the following command to check whether the current node or cluster can pull images.

     ```bash
     docker pull registry.cn-shanghai.aliyuncs.com/jibudata/velero-installer:xxx
     ```

  3. If the output shows insufficient resources in the cluster, please ensure [your cluster has sufficient resources](#kubernetes-cluster-resource-request). 

- `restic` DaemonSet errors.

  1. Run the following command to view the causes of errors.

     ```bash
     kubectl -n qiming-backend describe pod <restic pod name>
     ```

  2. The `restic` DaemonSet accesses the PVC data for backup by mounting the kubelet directory `/var/lib/kubelet/pods`. If the kubelet path of your Kubernetes cluster is different from that path, run the following command to change the value of `spec.template.spec.volumes.hostPath.path` to the correct path and save the changes.

     ```bash
     kubectl edit daemonset restic -n qiming-backend
     ```


## Backup troubleshooting

### Backup job remains in progress

1. Run the following command to view the information about backup jobs.

   ./velero get backups
   ```

2. Run the following command to view the details of the backup jobs remaining in progress and do troubleshooting according to the details.

   ```bash
   ./velero describe backup <backup job name> --details
   ```

### Backup job failure

1. Run the following command to view the information about backup jobs.

   ```bash
   ./velero get backups
   ```

2. Run the following command to view the details of the failed backup jobs and do troubleshooting according to the output in `Errors`.

   ```bash
   ./velero describe backup <backup job name> --details
   ```

## View backup/recovery CR information

### View CRs of a backup job

1. Run the following command to view all the CRs of the backup jobs.

   ```bash
   $ kubectl get backups.velero.io -n qiming-backend
   NAME                      AGE
   test-backup-4lx3w-vfg5q   2d19h
   ```

   <Notice type='note'>

   The prefix of the backup CR name is the backup job name created by the system. For example, if you create a backup plan named `test-backup1`, then the corresponding backup job CR name is `test-backup1-xxxxx-xxxxx`.

   </Notice>

2. Run the following command to view the status of the backup job CR.

   ```bash
   kubectl get backups.velero.io -n qiming-backend <backup job CR name> -o yaml
