Backblaze B2, Cloudflare R2, Wasabi, MinIO

Any storage that speaks S3 works: fill in the Endpoint field and the rest is the same as AWS.

The app speaks plain S3, so any service that does too is a backup place. The only difference from AWS is the Endpoint field: the address of the service, which you copy from its own pages.

01 · The fields, service by service
Backblaze B2
Endpoint
The Endpoint shown on the bucket’s page, with https:// in front: https://s3.eu-central-003.backblazeb2.com
Region
The part of the endpoint between s3. and .backblazeb2.com: eu-central-003
Keys
Application Keys: make one for this bucket only. Its keyID is the access key, its applicationKey the secret key.
Cloudflare R2
Endpoint
Shown under the bucket’s settings: https://<account id>.r2.cloudflarestorage.com
Region
auto
Keys
R2 API tokens: Object Read & Write on the one bucket. The token gives an Access Key ID and a Secret Access Key.
Wasabi
Endpoint
The service URL of the bucket’s region: https://s3.eu-central-2.wasabisys.com
Region
The bucket’s region: eu-central-2
Keys
Access Keys in the Wasabi console.
Hetzner Object Storage
Endpoint
The location’s address: https://fsn1.your-objectstorage.com
Region
The location: fsn1
Keys
S3 credentials made in the Hetzner console.
MinIO, your own
Endpoint
Your server’s address: https://minio.example.com, with :9000 at the end if it uses that port
Region
us-east-1, unless you set another
Keys
An access key made in the MinIO console for this bucket.
02 · The same four rules
  • Make the bucket private. The app never needs a public bucket.
  • Make a key that can reach only that bucket, and only to list, write, read and delete files in it. Every service above can do that.
  • The endpoint must start with https://; a plain http:// address is refused.
  • Then exactly as with AWS: Test connection, Save and start backup. See Test connection, Save.
