Create Backup with specific deployment and all pods and then restore the backup

[menal009]

Testcase Precondition:

1. Kahu project installed in given name-space (test-kahu)
2. All below pods should be up and running:
   a. backup service
   b. Meta service with nfs provider
   c. nfs-server
3. Metadata location is created already
4. Namespace test-ns is created and contains some of the kubernetes resources
   5.Namespace restore-ns is created

Testcase steps:

1. Create below backup CR using kubectl command
   (use kubectl create -f <backup.yaml>)
   apiVersion: kahu.io/v1
   kind: Backup
   metadata:
   name: backup-Kahu-0001
   spec:
   includeNamespaces: [test-ns]
   metadataLocation: nfs
   includeResources:

• name:
  kind: Pod
  isRegex: true
• name:
  kind: Deployment
  isRegex: true

2. Use kubectl describe backup -n test-kahu
3. Get inside nfs server pod and check for the content inside mount path given
   (use command kubectl exec -ti -n test-kahu /bin/sh)
4. Create a restore CR on new namespace (restore-ns)
   apiVersion: kahu.io/v1
   kind: Restore
   metadata:
   name: restore-Kahu-0001
   Spec:
   backupName: backup-Kahu-0001
   namespaceMapping:
   test-ns : restore-ns
   Expected Result:
5. In step 2,
   a) Verify that backup stage is Finished and State is Completed
   b) Verify the resource list in status shows all the required resources
6. In step 3, verify that
   a) tar file is created with name of backup
   b) After untar file, All pods and the specific deployment mentioned are backuped.
7. In step4, verify that
   a) Backed up specific deployment and pods are up in new namespace restore-ns

Why this issue to fixed / feature is needed(give scenarios or use cases):
This is a testcase which is to automated to make sure deployment is properly backed up and
Restored.
