#### Key rotation

S3 clients can change the client-provided key of an existing object. Therefore an S3 client must perform a S3 COPY operation where the copy source and destination are equal. Further the COPY request headers must contain the current and the new client key:

# MinIO FTP/SFTP Server

MinIO natively supports FTP/SFTP protocol, this allows any ftp/sftp client to upload and download files.

Currently supported `FTP/SFTP` operations are as follows:

| ftp-client commands | supported |
|:-------------------:|:----------|
| get                 | yes       |
| put                 | yes       |
| ls                  | yes       |
| mkdir               | yes       |
| rmdir               | yes       |

client = mqtt.Client(client_id="myclientid",clean_session=False)

client.on_connect = on_connect
client.on_message = on_message

client.connect("localhost",1883,60)
client.loop_forever()
```

Execute this example python program to watch for MQTT events on the console.

```py
python mqtt.py
```

Open another terminal and upload a JPEG image into `images` bucket.

```
mc cp myphoto.jpg myminio/images

## Get started

In this document we will explain in detail on how to configure admin users.

### 1. Prerequisites

- Install mc - [MinIO Client Quickstart Guide](https://min.io/docs/minio/linux/reference/minio-mc.html#quickstart)
- Install MinIO - [MinIO Quickstart Guide](https://min.io/docs/minio/linux/index.html#quickstart-for-linux)

`config.json` and bucket DNS SRV records. `MINIO_DOMAIN` indicates the domain suffix for the bucket which
will be used to resolve bucket through DNS. For example if you have a bucket such as `mybucket`, the
client can use now `mybucket.domain.com` to directly resolve itself to the right cluster. `MINIO_PUBLIC_IPS`
points to the public IP address where each cluster might be accessible, this is unique for each cluster.

- The S3 bucket, Access Key and Secret Key have to be created before and outside of Veeam.
- Configure the minio client for the Veeam MinIO endpoint - <https://min.io/docs/minio/linux/index.html#quickstart-for-linux>

## Setting up an S3 compatible object store for Veeam Backup and Replication

### Create a bucket for Veeam backups

export MINIO_IDENTITY_OPENID_CLIENT_ID="843351d4-1080-11ea-aa20-271ecba3924a"
minio server /mnt/data
```

#### Casdoor

```
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
export MINIO_IDENTITY_OPENID_CONFIG_URL=http://CASDOOR_ENDPOINT/.well-known/openid-configuration
export MINIO_IDENTITY_OPENID_CLIENT_ID="843351d4-1080-11ea-aa20-271ecba3924a"
minio server /mnt/data
```

root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.

You can also connect using any S3-compatible tool, such as the MinIO Client `mc` commandline tool. See
[Test using MinIO Client `mc`](#test-using-minio-client-mc) for more information on using the `mc` commandline tool. For application developers,

- Navigate to a node with the Spark client and access the spark2-client directory:

```
cd /usr/hdp/current/spark2-client
su spark
```

- Run the Apache Spark Pi job in yarn-client mode, using code from **org.apache.spark**:

```
./bin/spark-submit --class org.apache.spark.examples.SparkPi \
    --master yarn-client \
    --num-executors 1 \
    --driver-memory 512m \
