body: <p>I got Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 91 bytes) error while trying to backup database on online rest server using Codeigniter dbutil backup() function.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>    $this-&gt;load-&gt;dbutil();
      $backup =&amp; $this-&gt;dbutil-&gt;backup(); 
      $this-&gt;load-&gt;helper('file');
      write_file('./uploads/db/mybackup.gz', $backup);
  </code></pre>
