Is there a way to have an automatic back up of the data?

É possível programar backup ou export automática?

Uma rotina para backup é feita automaticamente uma vez por dia.

You may use the Reports to Cloud app in order to have the data synced with your Dropbox account: https://apps.jotform.com/app/reports_to_cloud 

You may also use the Daily Digest app in order to have submissions emailed in bulk: http://digest.jotform.io/

And you may also integrate your form with third party apps such as Google Drive, Dropbox and Google Spreadsheet in order to have the data saved there too. Here are the guides:
