首先需要创建一个角色专门为快照进行同步，且赋予它两个IAM策略（上面创建快照文档中均有说明）

角色本身有个信任源，需要修改角色信任关系，让其信任OpenSearch服务

允许读写桶的策略，这里的策略资源名称为arn:aws:iam::576184071779:policy/es-snapshot-s3-access，

                    "arn:aws:s3:::elasticserch-snapshot-backup"

            },
            {
                "Action": [
                    "s3:GetObject",
                    "s3:PutObject",

                ]
            }
        ]
    }

是将这个角色的读写桶的权限交给ElasticSearch（AWS里面叫OpenSearch），这里我们称为权限传递是将这个角色的读写桶的权限交给ElasticSearch（AWS里面叫OpenSearch），这里我们称为权限传递，可见传递角色为arn:aws:iam::576184071779:role/es-snapshot，传递给ES服务

使用 awscurl 发起请求创建快照库（这里一定要用awscurl，否则OpenSearch服务不知道请求者的身份），如果已经配置了 AWS CLI，awscurl 可以使用相同的凭证文件（通常位于 ~/.aws/credentials）

代码块

language	bash

# 创建s3快照库
awscurl --service es --region ap-northeast-1 -XPUT 'https://search-starcoin-es2-47avtmhexhbg7qtynzebcnnu64.ap-northeast-1.es.amazonaws.com/_snapshot/my-snapshot-repo?pretty' -H 'Content-Type: application/json' -d '{"type": "s3", "settings": {"role_arn": "arn:aws:iam::576184071779:role/es-snapshot", "region": "ap-northeast-1", "bucket": "elasticserch-snapshot-backup"}}
{
  "acknowledge": true
}

# 创建快照
PUT _snapshot/my-snapshot-repo/snapshot-20240917
{
  "acknowledge": true
}

在kibana的devtool中查看快照的创建进度，若状态为SUCCESS 在kibana的devtool中查看快照的创建进度，若状态为 SUCCESS 说明创建成功
