-The backup module will first try to authenticate itself using AWS IAM. If the authentication fails then it will try to authenticate with `Option 2`.
+The backup module first tries to authenticate using AWS IAM. If IAM authentication fails, it falls back to the configured access key and secret access key.
 
 #### Option 2: With access key and secret access key
 
+These environment variables are named for AWS, but they also apply to S3-compatible object stores that issue access-key credentials.

 | `AWS_ACCESS_KEY_ID` | The id of the AWS access key for the desired account. |
 | `AWS_SECRET_ACCESS_KEY` | The secret AWS access key for the desired account. |

+#### S3-compatible endpoints
+
+To use an S3-compatible object store, set `BACKUP_S3_ENDPOINT` to the provider's S3 endpoint host, optionally including a port, and authenticate with `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`. Set `AWS_REGION` if your provider requires one.
