django backblaze b2 storage using b2sdk (b2sdk is official backblaze python library)

Documentation

The full documentation is at https://django-b2.readthedocs.io.

Quickstart

Install django-b2:

pip install django-b2

Add into your settings:

MEDIA_URL = '/media/'
DEFAULT_FILE_STORAGE = 'django_b2.storage.B2Storage'                 # if used without django-tenant-schemas
# DEFAULT_FILE_STORAGE = 'django_b2.tenant_storage.TenantB2Storage'  # if used with django-tenant-schemas
B2_APP_KEY_ID = 000xxxxxxxxxxxx000000000n
B2_APP_KEY = keyvalue
B2_BUCKET_NAME = bucketname
# optional, see Usage (docs/usage.rst):
B2_FORCE_UNIQUE = False
# optional, see Usage (docs/usage.rst):
MEDIA_ROOT = ..
B2_LOCAL_MEDIA = ..  # "", "M", "L", "ML"

Using outside of Django:

from django_b2.backblaze_b2 import BackBlazeB2
b2 = BackBlazeB2()
b2.authorize("production", application_key_id, application_key)
b2.set_bucket(bucket_name)
with open(filename, 'rb') as f:
    b2.upload_file(filename, f)
content = b2.download_file(filename)
with open(filename2, 'wb') as f:
    f.write(content)

Features

  • Django media storage (with storage.py) or general python access to BackBlaze B2 (without usage of storage.py).
  • Upload single file to B2 (call backblaze_b2.py as script; new in 0.2.0)
  • Backup a postgres database to B2 (use script pgtob2.sh; new in 0.2.0)
  • Optionally cache media files locally for immediate access or for long time faster access.
