`fae684da`) in a single bucket. Versioning protects you from unintended overwrites, deletions, protect objects with retention policies.

To control data retention and storage usage, use object versioning with [object lifecycle management](https://github.com/minio/minio/blob/master/docs/bucket/lifecycle/README.md).  If you have an object expiration lifecycle policy in your non-versioned bucket and you want to maintain the same permanent delete behavior when on versioning-enabled bucket, you must add...

/// tip | Tipp

Wenn Sie <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> als Ihren Editor verwenden, können Sie das <a href="https://github.com/koxudaxi/pydantic-pycharm-plugin/" class="external-link" target="_blank">Pydantic PyCharm Plugin</a> ausprobieren.

Es verbessert die Editor-Unterstützung für Pydantic-Modelle, mit:

* Code-Vervollständigung

# Dateien im Request { #request-files }

Sie können Dateien, die vom Client hochgeladen werden, mithilfe von `File` definieren.

/// tip | 提示

使用 <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> 编辑器时，推荐安装 <a href="https://github.com/koxudaxi/pydantic-pycharm-plugin/" class="external-link" target="_blank">Pydantic PyCharm 插件</a>。

该插件用于完善 PyCharm 对 Pydantic 模型的支持，优化的功能如下：

* 自动补全
* 类型检查
* 代码重构
* 查找
* 代码审查

  - OpenID/OIDC service accounts

- On versioned buckets, FTP/SFTP only operates on latest objects, if you need to retrieve
  an older version you must use an `S3 API client` such as [`mc`](https://github.com/minio/mc).

- All features currently used by your buckets will work as is without any changes
  - SSE (Server Side Encryption)
  - Replication (Server Side Replication)

## Prerequisites

- Install MinIO - [MinIO Quickstart Guide](https://docs.min.io/community/minio-object-store/operations/deployments/baremetal-deploy-minio-on-redhat-linux.html)
- Configure etcd - [Etcd V3 Quickstart Guide](https://github.com/minio/minio/blob/master/docs/sts/etcd.md)

### 2. Create a new user with canned policy

これを動作させるには、**Python 3.7** 以上を使用するか、**Python 3.6** では"backports"をインストールする必要があります:

```
pip install async-exit-stack async-generator
```
