I usually take backup of the entire database before importing new configurations, but this time I didn't and now I need to double check something with old version of database. Is it possible to just revert the changes done by drush cim?

I am using Drupal 8.

Googling for this specific situation didn't give me any solution.

    Configuration is saved in yml files inside the /config folder and not the database. If you use a version control system like GIT, you could see and also revert changes.

  • You might still need a database backup, reverting config doesn't restore deleted content.

No, you can't revert drush cim without a backup (or alternate config export) of some sort. If you don't have a backup, you're out of luck.

One safety measure to prevent this kind of problem is to write a script that backs up your database and then calls drush cim. Then, only run the script to do a config import, and you can ensure you have always made a backup first.

    Another safety measure is to use version control ;+)
