Velero (formerly Heptio Ark) gives you tools to back up and restore your Kubernetes cluster resources and persistent volumes. You can run Velero with a cloud provider or on-premises.

### How it's work
Each Velero operation (on-demand backup, scheduled backup, restore) is a custom resource, stored in etcd. A backup opertaion is uploads a tarball of copied Kubernetes objects into cloud object storage. After that calls the cloud provider API to make disk snapshots of persistent volumes, if specified. Optionally you can specify hooks to be executed during the backup. When you create a backup, you can specify a TTL by adding the flag `--ttl <DURATION>`.

### Velero supported providers

| AWS S3 | AWS EBS |
| Google Cloud Storage | Google Compute Engine Disks |
| Azure Blob Storage | Azure Managed Disks |

```

### Create Backup
```
velero backup create nginx-backup --selector app=nginx
velero backup describe nginx-backup
velero backup logs nginx-backup
velero backup get

velero schedule create nginx-daily --schedule="0 1 * * *" --selector app=nginx
velero schedule get
velero backup get
```

### Restore test
```
kubectl delete ns nginx-example

velero restore create --from-backup nginx-backup
velero restore get

kubectl get po -n nginx-example
```
