Bom trabalho, @italo!

Sim, deve ser seguro executar o discourse-setup novamente e seus dados devem estar intactos.

Você pode fazer

```plaintext
cd /var/discourse
./launcher start app

```

Isso reiniciará seu contêiner antigo.

```plaintext
./launcher enter app
discourse backup

```

Isso fará um backup.

Digite `exit` para sair do contêiner.
