ruby on rails - transfer db from one heroku app to another faster

Question

Is there a faster way to transfer my production database to a test app?

Currently I'm doing a heroku db:pull to my local machine then heroku db:push --app testapp but this is becoming time consuming. I have some seed data but it is not nearly as accurate as simply testing with my real-world data. And since they're both stored on a neighboring AWS cloud, there must be a faster way to move the data?

I thought about using a heroku bundle, but I noticed the animate command is gone?

bundles:animate <bundle>     # animate a bundle into a new app

Answer 1

It's quite common to migrate databases between staging, testing and production environments for Rails Apps. And heroku db:pull/push is painfully slow. The best way I have found so far is using Heroku PG Backups add-on and it's free. I followed following steps to migrate production database to staging server:

1) Create the backup for the production-app db

heroku pg:backups capture --app production-app

This will generate b001 backup file from the main database (usually production db in database.yml)

2) To view all the backups (OPTIONAL)

heroku pg:backups --app production-app

3) Now use the pg:backups restore command to populate staging server database from the last backup file on production server

heroku pg:backups restore $(heroku pg:backups public-url --app production-app) DATABASE_URL --app staging-app

Remember that restore is a destructive operation, it will delete existing data before replacing it with the contents of the backup file.
