【 使用环境 】生产环境
【 OB or 其他组件 】 OCP 管理集群备份
【 使用版本 】 V 4.3.5
【问题描述】 OCP 管理集群备份，备份minio S3存储介质失败
S3用户权限设置
OCP备份配置
备份错误显示
我也按照测试方式去测试了一下
./ob_admin test_io_device
-d’s3://obbackup-bucket/newsrec_obbackup/’
-s’host=http://minio-content.service.xxx.org:8380&access_id=xxxx&access_key=xxxxxx’
日志如下：
ob_admin_rs.log (4.0 KB)
ob_admin.log (94.3 KB)
【附件及日志】推荐使用OceanBase敏捷诊断工具obdiag收集诊断信息,详情参见链接（右键跳转查看）：
希望帮忙排查一下 。
从ob_admin.log看有两个报错，第2个报错麻烦先用aws的命令行工具测试下list接口兼容性

第2个报错也提示访问s3存储失败，解析远端IP地址失败，测试下这台机器访问这个s3存储的连通性
curl -v bucket-name.host
例如：
curl -v http://s3-436751-abc-dataa-all-test.s3.cn-north-1.amazonaws.com.cn
地址解析方面出问题了吗
黑屏配置配置备份可以成功吗？
ob 4219 开始支持 S3 对象存储访问新增可选参数 addressing_model
支持 S3 路径配置可选参数 addressing_model，可选参数值：virtual_hosted_style/path_style。S3 路径配置addressing_model=path_style 后，支持以 path style addressing model 访问对象存储；配置 addressing_model=virtual_hosted_style 或不配置可选参数 addressing_model 默认以 virtual hosted style 访问对象存储。
一般自建的s3仅支持path_style方式，
目前ocp还不支持，内部已经有排期了，如果需要这种方式，当前只能通过命令行的方式

https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000002016885
结论：
自建s3仅支持path style方式，OCP预计4.3.6支持path style，目前不支持
绕过方式：配置直接使用IP访问minio
