使用Django 1.10，Django的DBBACKUP 3.0和PostgreSQL-9.5.4django-dbbackup的正確設置是什麼？
我從文檔http://django-dbbackup.readthedocs.io/en/stable/installation.html配置設置中寫道，但得到這個錯誤：
Traceback (most recent call last):

return getattr(module, class_name)
AttributeError: module 'dbbackup.storage' has no attribute 'filesystem_storage'
During handling of the above exception, another exception occurred:
