* Replace `<YOUR_STORAGE_CLASS_NAME>` with `gp2`. This is AWS's default `StorageClass` name.
* (Optional) If you have multiple clusters and you want to support migration of resources between them, in file `examples/aws/10-deployment.yaml`:
* Uncomment the environment variable `AWS_CLUSTER_NAME` and replace `<YOUR_CLUSTER_NAME>` with the current cluster's name. When restoring backup, it will make Ark (and cluster it's running on) claim ownership of AWS volumes created from snapshots taken on different cluster.
The best way to get the current cluster's name is to either check it with used deployment tool or to read it directly from the EC2 instances tags.
The following listing shows how to get the cluster's nodes EC2 Tags. First, get the nodes external IDs (EC2 IDs):
```bash
kubectl get nodes -o jsonpath='{.items[*].spec.externalID}'
```
Copy one of the returned IDs `<ID>` and use it with the `aws` CLI tool to search for one of the following:
* The `kubernetes.io/cluster/<AWS_CLUSTER_NAME>` tag of the value `owned`. The `<AWS_CLUSTER_NAME>` is then your cluster's name:
```bash
aws ec2 describe-tags --filters "Name=resource-id,Values=<ID>" "Name=value,Values=owned"
```
* If the first output returns nothing, then check for the legacy Tag `KubernetesCluster` of the value `<AWS_CLUSTER_NAME>`:
```bash
aws ec2 describe-tags --filters "Name=resource-id,Values=<ID>" "Name=key,Values=KubernetesCluster"
```
