How to copy a heroku database between enviroments (apps)


Lets say you have two enviroments running as Heroku apps. These will be the stage and production enviroments accordingly:

  • app-stage
  • app-prod

How, you’ve noticed that the data on the stage is lagging begind, is corrupted do to some strange code-fu, and you just want to get it up and running again with production data.

heroku pgbackups:capture --expire -a app-prod # make a backup of the database
heroku pgbackups:restore HEROKU_POSTGRESQL_COPPER -a app-stage `heroku pgbackups:url -a app-prod`

You will be asked to input the application name to confirm a potentially destructive action. Also - if you have another database than HEROKU_POSTGRESQL_COPPER you will need to change that part.
