Let's perform the following steps to take a backup of our application:

1. If you have an application and persistent volumes associated with the backup labeled already, you can skip to Step 5. Otherwise, create a namespace and a PVC using the following example code:

$ cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Namespace
metadata:
 name: backup-example
 labels:
 app: app2backup
EOF

2. Create a PVC in the backup-example namespace:

$ cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc2backup
  namespace: backup-example
  labels:
    app: app2backup
spec:
  accessModes:
    - ReadWriteOnce
  storageClassName: openebs-cstor-default
  resources:
    requests:
      storage: 4Gi
EOF

3. Create a pod that will use the PVC and write to the /data/out.txt file inside the pod using the sample myapp.yaml manifest under the src/chapter6/kasten directory:

$ kubectl apply -f - kasten/myapp.yaml

4. Verify that our myapp pod writes data to the volume:

$ kubectl exec -it myapp cat /data/out.txt -nbackup-example

5. On the Kasten Dashboard, click on Unmanaged applications:

6. In the backup-example namespace, click on Create a policy:

7. Enter a name and select the Snapshot action:

8. Select Daily as the Action Frequency:

9. Click on Create Policy:

By following these steps, you will have created your first backup using the policy, as well as a schedule for the following backup jobs.
