1、修改配置文件：
path.repo: /data/snapshot # 先创建这个目录存放快照， mkdir /data/snapshot
2、创建仓库：
curl -XPUT http://localhost:9200/_snapshot/backup -d '
{
"type":"fs",
"settings":{"location":"/data/snapshot","compress": true}
}'
curl -XPUT http://localhost:9200/_snapshot/backup -H "Content-Type: application/json" -d '
{
"type":"fs",
"settings":{"location":"/data/snapshot","max_snapshot_bytes_per_sec" : "1000mb","max_restore_bytes_per_sec" : "1000mb","compress" : true}
}'
3、如果需要可以更新仓库：
curl -XPOST http://localhost:9200/_snapshot/backup/ -d '
{
"type": "fs",
"settings": {
"location": "/data/snapshot",
"max_snapshot_bytes_per_sec" : "100mb",
"max_restore_bytes_per_sec" : "100mb",
"compress" : true
}
}'
4、创建快照：
curl -XPUT http://localhost:9200/_snapshot/backup/snapshot1?wait_for_completion=true # 创建一个名称为snapshot1的快照，通常你会希望你的快照作为后台进程运行，不过有时候你会希望在你的脚本中一直等待到完成。这可以通过添加一个 wait_for_completion 标记实现。
time curl -XPUT http://localhost:9200/_snapshot/backup/snapshot2?wait_for_completion=true -d '{"indices": "fofapro,index2"}' # 只快照某些索引
5、查看快照的状态：
curl -XGET http://localhost:9200/_snapshot/backup/_all?pretty=true # 查看所有快照状态
6、查看快照的进度等信息：GET http://localhost:9200/_snapshot/backup/snapshot3/_status # snapshot_3 是快照名称
7、快照恢复：
curl -XPOST http://localhost:9200/_snapshot/backup/snapshot1/_restore?wait_for_completion=true
恢复某个索引
time curl -XPOST " http://localhost:9200/_snapshot/backup/snapshot4/_restore?wait_for_completion=true" -d '{
"indices": "netinfo-2016.12.21",
"ignore_unavailable": "true",
"include_global_state": false,
"rename_pattern": "netinfo-2016.12.21",
"rename_replacement": "netinfotest"
}'
这时有可以会报错：cannot restore index because it's open
需要先关闭所有索引：
curl -XPOST http://localhost:9200/index_name/_close
或
curl -XPOST http://localhost:9200/_all/_close
因为做快照时，索引是打开的，恢复过后索引也是打开的。
8、删除快照：
curl -XDELETE http://localhost:9200/_snapshot/backup/snapshot1 #取消快照也是同样的操作
9、删除仓库：
curl -XDELETE http://localhost:9200/_snapshot/backup
