+### Esempi
+
+##### Non ho voglia di fare un ruolo per il mio super servizio ma vorrei usare il ruolo `stable/restic` per fare il setup del backup.
+È la situazione che sto documentando, la macchina contiene un etherpad di cui voglio gestire i backup.
+
+Creo un playbook temporaneo (backup.yml)
+```yaml
+---
+# SETUP BACKUP TO EXISTENT VM
+- name: Setup backup
+  hosts: paddone
+  roles: ['stable/restic']
+  vars:
+    restic_databases:
+      - {name: 'etherpad', dump_command: sudo -Hiu postgres pg_dump -Fc etherpad}
+```
+
+Lancio `ansible-playbook backup.yml`
+Fine.
