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.
  -c, --clean           Clean up old backup files
  -d DATABASE, --database=DATABASE
                        Database to backup (default: everything)
  -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
                        Exclude tables data from backup (-x 'public.table1, public.table2')

dbrestore

You may optionally specify a servername if you you want to backup a database image that was created from a different server. You may also specify an explicit local file to backup from.

Usage: ./manage.py dbrestore [options]

Options:
  --noinput             Tells Django to NOT prompt the user for input of any

  -s SERVERNAME, --servername=SERVERNAME
                        Use a different servername backup
  -c, --decrypt         Decrypt data before restoring

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.
