Django PostgreSQL Copy

The package django-pg-copy provides Django management commands for backing up and restoring PostgreSQL databases. These were developed for copying production databases to development, to allow developers to share images with one another, or bring local development databases up to date.

Installation

pip install django-pg-copy

Then add 'pg_copy', to your INSTALLED_APPS list. It is recommended that it is used in all environments (development, production) so that you can use it against different instances of your database.

Settings

PG_COPY_BACKUP_PATH = 'db_backup'

By default, PostgreSQL backups will be stored in a directory called db_backup where you run the command. This setting will override that location.

It is also recommended to add this path to your .gitignore file, if the path falls under your version control repository.

Example Commands

python manage.py pg_backup --settings=config.settings.production --database=default --filename=my_backup.sqlc

This command will create a backup in the same directory as manage.py called my_backup.sqlc using the default settings from DATABASES using the Django settings file config.settings.production.

python manage.py pg_backup

This command will create a backup in the directory ./db_backup/ (or the directory you specified with PG_COPY_BACKUP_PATH) called [timestamp].sqlc using the default settings from DATABASES using the default Django settings file resolved by manage.py.

python manage.py pg_restore

This command will provide a list of backup files in PG_COPY_BACKUP_PATH that can be restored. After selecting a backup file, it will confirm that the user wants to overwrite the destination database by showing which server and database will be overwritten from the settings.

python manage.py pg_restore --filename=my_file.sqlc

This command will read the file my_file.sqlc and confirm that the user wants to overwrite the destination database by showing which server and database will be overwritten from the settings.
