Label non-backup nodes

If your application cluster consists of non-backup nodes (whose applications and data are not backed up by Portworx Backup), you can apply a predefined label (portworx.io/nobackup) for such nodes. You can apply this label for all license types. Portworx Backup cluster identifies nodes with this label and excludes those nodes from the license count.

To flag a node as a non-backup node, run the following commands.

Verify whether the predefined label, portworx.io/nobackup is associated with the node:
```
kubectl get nodes --show-labels|grep portworx.io/nobackup=true
```
If no, apply the predefined label:
```
kubectl label node <nodename> portworx.io/nobackup=true
```
note
After a node is labeled as a non-backup node, Portworx Backup skips this node for licensing and displays the reduced node count in the license page after a few minutes.

To remove the label and convert a node to a backup node later, run the below command:
```
kubectl label node <nodename> portworx.io/nobackup-
```
