elasticsearch - Windows上的ElasticSearch备份，Linux上的Restore

Question

我正在尝试在Windows上的ElasticSearch 6.2.2中备份索引并在Linux上的ElasticSearch 6.2.3上还原它。我正在执行以下步骤，但是在Linux机器(基于https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-snapshots.html)上却看不到快照:

在Windows上注册快照存储库

PUT /_snapshot/my_backup
{
   "type": "fs",
   "settings": {
      "location": "C:\\EsBackup",
      "compress": true
  }
}

在Windows上创建快照

PUT /_snapshot/my_backup/bcp?wait_for_completion=true
{
"indices":"myindex"
}

检查快照是否已创建

GET /_snapshot/my_backup/bcp

显示成功

{
  "snapshots": [
    {
      "snapshot": "bcp",
      "uuid": "xGLvw4JnRqadcyg4fxH1HA",
      "version_id": 6020299,
      "version": "6.2.2",
      "indices": [
        "bcp"
      ],
      "include_global_state": true,
      "state": "SUCCESS",
      "start_time": "2018-05-10T16:48:22.970Z",
      "start_time_in_millis": 1525970902970,
      "end_time": "2018-05-10T16:48:36.816Z",
      "end_time_in_millis": 1525970916816,
      "duration_in_millis": 13846,
      "failures": [],
      "shards": {
        "total": 3,
        "failed": 0,
        "successful": 3
      }
    }
  ]
}

我将文件复制到linux，并检查文件的大小和数量是否相同。 (大约200个文件，大小为500MB)。我将所有内容复制到文件夹 ~/elasticsearch-6.2.3/backup
初始化存储库

curl -X PUT "localhost:9200/_snapshot/my_backup" -H 'Content-Type: application/json' -d'{"type": "fs","settings": {"location": "~/elasticsearch-6.2.3/backup","compress": true}}'

并得到确认: {"acknowledged":true}
所以我检查哪些快照可用

curl -X GET "localhost:9200/_snapshot/my_backup/_status"

但列表为空 {"snapshots":[]}
并还原

curl -X POST "localhost:9200/_snapshot/my_backup/bcp/_restore?pretty"

返回错误

{
  "error" : {
    "root_cause" : [
      {
        "type" : "snapshot_restore_exception",
        "reason" : "[my_backup:bcp] snapshot does not exist"
      }
    ],
    "type" : "snapshot_restore_exception",
    "reason" : "[my_backup:bcp] snapshot does not exist"
  },
  "status" : 500
}

我想走哪一步？我试图_verify存储库，它是有效的。版本6.2.2和6.2.3应该兼容。

在elasticsearch.yml文件中添加以下内容:

path.repo: /path/to/repo
