+# Available Backends
+
+In theory [all the restic backends](https://restic.readthedocs.io/en/stable/030_preparing_a_new_repo.html) are supported.
+
+Those tested are the following:
+
+> ℹ️ You can also [specify the `env` variables in a config file](/backend/env) to separate them from the config file.
+
+## Local
+
+```yaml
+backends:
+  name-of-backend:
+    type: local
+    path: /data/my/backups
+```
+
+## Backblaze
+
+```yaml
+backends:
+  name-of-backend:
+    type: b2
+    path: 'bucket_name'
+    # Or With a path
+    # path: 'bucket_name:/some/path'
+    env:
+      B2_ACCOUNT_ID: 'backblaze_keyID'
+      B2_ACCOUNT_KEY: 'backblaze_applicationKey'
+```
+
+#### API Keys gotcha
+
+If you use a _File name prefix_ when making the application key, do not include a leading slash. Make sure to include this prefix in the path (e.g. `path: 'bucket_name:my/path'`).
+
+## S3 / Minio
+
+```yaml
+backends:
+  name-of-backend:
+    type: s3
+    path: s3.amazonaws.com/bucket_name
+    # Minio
+    # path: http://localhost:9000/bucket_name
+    env:
+      AWS_ACCESS_KEY_ID: my_key
+      AWS_SECRET_ACCESS_KEY: my_secret
+```
+
+## SFTP
+
+For SFTP to work you need to use configure your host inside of ~/.ssh/config as password prompt is not supported. For more information on this topic please see the [official docs](https://restic.readthedocs.io/en/stable/030_preparing_a_new_repo.html#sftp) on the matter.
+
+```yaml
+backends:
+  name-of-backend:
+    type: sftp
+    path: my-host:/remote/path/on/the/server
+```
+
+## Rest Server
+
+See [here](https://github.com/restic/rest-server) for how to install a rest server backend and [here](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#rest-server) for further documentation.
+
+```yaml
+backends:
+  name-of-backend:
+    type: rest
+    path: http://localhost:8000/repo_name
+    # Or authenticated
+    path: https://user:pass@host:6969/path
+```
+
+Optionally you can set user and password separately
+
+```yaml
+backends:
+  rest:
+    type: rest
+    path: http://localhost:6969/path
+    key: ...
+    rest:
+      user: user
+      password: pass
+```
