title: Creating a backup of BigQuery project
body: <p>I wonder what is the best strategy to backup data in BigQuery?</p>
  
  <p>So far we are using BigQuery to store many different datasets coming from different sources. We do store the raw data (csv files) aside but re-creating the whole thing from them will be difficult and time-consuming task.</p>
  
  <p>Is there a way to make a snapshot of all datasets/tables in the project?   </p>
