Occasionally, even experienced Drupal administrators will make a mistake and need to revert their latest database changes. Nobody is that good at Drupal and in some cases, it’s not anyone’s fault really, but things go wrong. It is always best to backup your Drupal website database before and after making any changes to your Drupal site like Drupal core updates or Drupal module updates. It is also wise to make weekly or daily database backups if your site receives or adds content often.
