備份恢復數據

詳細請閱讀參考文檔 , 本人只在這裏做了一些基本的使用，針對的是單機環境

備份數據需要cluster有一個共享的文件系統，在這裏需要配置一個repo.path

elasticsearch.yml
path.repo: ["/opt/es_backup", "/mount/longterm_backups"]

創建倉庫名

PUT /_snapshot/my_fs_backup
{
    "type": "fs",
    "settings": {
        "location": "/opt/es_backup/Backup20171221.bk",
        "compress": true
    }
}

向倉庫備份index

全部備份
PUT /_snapshot/my_fs_backup/snapshot_1?wait_for_completion=true

指明index備份
PUT /_snapshot/my_fs_backup/snapshot_1?wait_for_completion=true
{
  "indices": "index_1,index_2",
  "ignore_unavailable": true,
  "include_global_state": false
}

用來查看備份的信息
GET /_snapshot/my_backup/snapshot_1
GET /_snapshot/my_backup/_all

查看備份操作執行狀態

GET /_snapshot/my_fs_backup/snapshot_1/_status

重新讀取數據

POST /_snapshot/my_backup/snapshot_1/_restore

POST /_snapshot/my_backup/snapshot_1/_restore
{
  "indices": "index_1,index_2",
  "ignore_unavailable": true,
  "include_global_state": true,
  "rename_pattern": "index_(.+)",
  "rename_replacement": "restored_index_$1"
}

禁用碎片分配

PUT _cluster/settings
{
  "persistent": {
    "cluster.routing.allocation.enable": "none"
  }
}

停止非必要的索引並執行同步刷新（可選）

POST _flush/synced

關閉節點

kill  1231
