Restoring an application

Let's perform the following steps to restore the application from its backup:

1. Delete the application and its PVC to simulate a data loss scenario:

$ kubectl delete pvc pvc2backup -nbackup-example
$ kubectl delete pod myapp -nbackup-example

2. Restore your application from your previous backup called myapp-backup:

$ velero restore create --from-backup myapp-backup

3. Confirm your application is running:

$ kubectl get pod -nbackup-example
NAME  READY STATUS  RESTARTS AGE
myapp 1/1   Running 0        10m

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

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

With that, you've learned how to restore an application and its volumes from its backup using Velero.
