Elasticsearch数据迁移从aliyun到aws

一. Aliyun Opensearch 快照备份

前言： Aliyun Opeasearch 6.8.6 迁移 Aws OpenSearch 7.10
数据量: 32.5G左右， 数据传输方法 Aliyun OSS -→ Aliyun ECS/ AWS EC2 --→ AWS S3

        备份还原方式： snapshot 离线快照，备份时间大概10-15分钟。

        还原时间： 35-55分钟(具体根据网络波动)
        xxxxxxx

1. 创建阿里云 oss 仓库用作快照的备份

endpoint: oss-cn-hongkong-internal.aliyuncs.com
bucket: meimei

2. 通过 kibana dev tools 创建快照存储库

登陆Aliyun Kibana
https://xxxxx.aliyuncs.com:5601/app/kibana

#新建快照仓库
PUT _snapshot/aliyun_es/
{
   
   
    "type": "oss",
    "settings": {
   
   
        "endpoint": "http://oss-cn-hongkong-internal.aliyuncs.com",
        "access_key_id": "xxxx",
        "secret_access_key":"xxxx",
        "bucket": "meimei",
        "compress": true,
        "chunk_size": "500mb",
        "base_path": "/"
    }
}

3. 进行全量快照备份 并 查看快照是否备份成功

#为全部索引创建快照备份,备份完等待10-15分钟才能够备份完全！！
PUT _snapshot/aliyun_es/snapshot_202220408


GET _snapshot/aliyun_es/_all

{
   
   
  "snapshots" : [
    {
   
   
      "snapshot" : "snapshot_202220408",  #这个快照的名字要记住，需要在aws中使用！！！
      "uuid" : "eP9EEmJtQ6i7HRjzdVEF0w",
      "version_id" : 6080699,
      "version" : "6.8.6",
      "indices" : [
        "message_index",
        "order_index"
      ],
      "include_global_state" : true,
      "state" : "SUCCESS",
      "start_time" : "2022-04-08T12:56:43.918Z",
      "start_time_in_millis" : 1649422603918,
      "end_time" : "2022-04-08T12:57:39.838Z",
      "end_time_in_millis" : 1649422659838,
      "duration_in_millis" : 55920,
      "failures" : [
