vim /etc/elasticsearch/elasticsearch.yml 
path.repo: ["/data/backups/es_backup"]    #备份目录，根据自己情况进行填写
systemctl restart elasticsearch.service 
mkdir -pv /data/backups/es_backup 
chmod 755 /data/backups/es_backup
chown elasticsearch:elasticsearch /data/backups/es_backup

2、创建仓库

备份数据之前，要创建一个仓库来保存数据，仓库的类型支持Shared filesystem, Amazon S3, HDFS和Azure Cloud。下面以文件系统为例

curl -H "Content-Type:application/json" -XPUT ‘127.0.0.1:9200/_snapshot/es_backup‘ -d ‘

    "type": "fs", 
    "settings": 
        "location": "/data/backups/es_backup" 
    
‘

3、备份索引

curl -H "Content-Type:application/json" -XPUT ‘127.0.0.1:9200/_snapshot/es_backup/snapshot_1‘

如果只想备份部分索引的话，可以加上indices 参数：

curl -H "Content-Type:application/json" -XPUT ‘127.0.0.1:9200/_snapshot/es_backup/snapshot_2‘ -d ‘
    
        "indices": "index_1,index_2"
    ‘

5 、查看备份信息

curl -H "Content-Type:application/json" -XGET ‘127.0.0.1:9200/_snapshot/es_backup/snapshot_1?pretty=true‘

6、数据恢复

curl -H "Content-Type:application/json" -XPOST ‘127.0.0.1:9200/_snapshot/es_backup/snapshot_1/_restore‘
