title: Is it possible to get back update made on a query without backup?
body: <p>I'm gonna ask a stupid but desperate question.</p>
  
  <p>Is it possible to get back a query who has been updated same with before without backup of the db.</p>
  
  <p>For example I have the sentence</p>
  
  <p><code>Hello world</code></p>
  
  <p>and someone did an update query to </p>
  
  <p><code>Hello hell</code></p>
  
  <p>Is there a possibility to go back to before or log where I can find when the original sentence has been created, or maybe (let's think everything is possible) a default backup of my db ?</p>
  
  <p>I'm using RAILS 5, and sqlite3</p>
  
  <p>Thank you</p>
