Best workflow for quick django database backup / restore

Hi,

I would like to know the best workflow for working with a database and pycharm please.

I setup GIT VCS for files so I can quickly go back to my files history in time, but what about the database ?

How do you guys do when you want to quickly revert changes or restore a database ?
For database scheme I know you can revert migrations with django, but what if I want to quickly restore a database content ?

I see you can quickly duplicate a database, but I'm not sure what this does exactly, how to use it, and if it is advisable to use this feature.
