备注：以下代码在kibana插件下运行：

# 创建一个备份用的仓库
# type:fs文件系统
# 支持Shared filesystem, Amazon S3, HDFS和Azure #Cloud
# location备份目录

 PUT /_snapshot/my_backup
{
     "type": "fs",
     "settings": {
         "location": "c:/mount/backups/my_backup"
     }
}

# 修改备份仓库属性
# max——snapshot_bytes_per_sec,创建快照速度
# max_restore_bytes_per_sec，还原快照速度

POST /_snapshot/my_backup/
{
    "type": "fs",
    "settings": {
        "location": "/mount/backups/my_backup",
        "max_snapshot_bytes_per_sec" : "50mb",
        "max_restore_bytes_per_sec" : "50mb"
    }
}

# 开始备份
#wait_for_completion等待完成参数,如果没有，则后台完成

PUT /_snapshot/my_backup/snapshot_1?wait_for_completion=true

# 查看快照

GET /_snapshot/my_backup/snapshot_1

# 查看所有快照

GET /_snapshot/my_backup/_all

# 快照详细信息

GET /_snapshot/my_backup/snapshot_1/_status

# 删除备份

DELETE /_snapshot/my_backup/snapshot_1

# 恢复snapshot_1里的全部索引

POST /_snapshot/my_backup/snapshot_1/_restore

# 恢复详细参数设置
# 参数indices 设置只恢复index_1索引，
# 参数rename_pattern 和rename_replacement 用来正则匹配要恢复的索引，并且重命名。
# 和备份一样，api会立刻返回值，然后在后台执行恢复，使用wait_for_completion 标记强制
# 同步执行

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

# 查看恢复的状态

GET /_recovery/restored_index_3
GET /_recovery/

# 取消恢复过程不管是正在备份，还是备份完成

DELETE /restored_index_3
