Django Database Backup
This Django application provides management commands to help backup and restore your project database and media files with various storages such as Amazon S3, Dropbox, local file storage or any Django storage.
It is made to:
- Allow you to secure your backup with GPG signature and encryption
- Archive with compression
- Deal easily with remote archiving
- Keep your development database up to date
- Use Crontab or Celery to setup automated backups

Why use DBBackup
This software doesn't reinvent the wheel, in a few words it is a pipe between your Django project and your backup storage. It tries to use the traditional dump & restore mechanisms, apply compression and/or encryption and use the storage system you desire.
It gives a simple interface to backup and restore your database or media files.
Management Commands
dbbackup
Backup your database to the specified storage. By default this will backup all databases specified in your settings.py file and will not delete any old backups. You can optionally specify a server name to be included in the backup filename.
Usage: ./manage.py dbbackup [options]
Options:
--noinput Tells Django to NOT prompt the user for input of any
kind.
-q, --quiet Tells Django to NOT output other text than errors.

-s SERVERNAME, --servername=SERVERNAME
Specify server name to include in backup filename
-z, --compress Compress the backup files
-e, --encrypt Encrypt the backup files
-o OUTPUT_FILENAME, --output-filename=OUTPUT_FILENAME
Specify filename on storage
-O OUTPUT_PATH, --output-path=OUTPUT_PATH
Specify where to store on local filesystem
-x EXCLUDE_TABLES, --exclude-tables=EXCLUDE_TABLES

Tests
Tests are stored in dbbackup.tests and to run them you must launch:
python runtests.py
In fact, runtests.py acts as a manage.py file and all Django commands
are available. So you could launch:
python runtests.py shell
to get a Python shell configured with the test project. Also all test command options are available and usable to run only a selection of tests. See Django test command documentation for more information about it.
There are even functional tests:
./functional.sh
See documentation for details.
To run the tests across all supported versions of Django and Python, you can use Tox. Firstly install Tox:
pip install tox
To run the tests just use the command tox in the command line. If you
want to run the tests against just one specific test environment you can run
tox -e <testenv>. For example, to run the tests with Python3.9 and
Django3.2 you would run:
tox -e py39-django32
The available test environments can be found in tox.ini.
