Does not work with Django 5.1 because get_storage_class is deprecated and removed.

Current Situation

Django DBBackup relies on function get_storage_class which is deprecated since version Django>=4.2 and has been removed in Django 5.1.

python manage.py dbbackup

Thank you for solving this issue, it works as expected with version 4.2.1. Cheers
