<help-section>
  <p>Here you can export all your data as a
    <strong>JSON</strong> for backups, but also to use it in a different context (e.g. you might want to export your projects in the browser and import them into the desktop version).
  </p>
  <p>The import expects valid JSON to be copied into the text area.
    <strong>NOTE: Once you hit the import button all your current settings and data will be overwritten!</strong></p>

  <section ng-if="vm.IS_ELECTRON">
    <p>There is also the option to do
      <strong>automatic backups</strong>. You can choose an interval in seconds of how often the backup should occur and a custom destination to where the backup should be saved. You can use `{unix}` and `{date}` inside the path string to add output a unix timestamp or a date at this location of the string. E.g. `/mypath/{date}.json` will save your data to `/mypath/2017-12-12.json.
