elasticsearch的備份和恢復（轉）

vim /etc/elasticsearch/elasticsearch.yml 
path.repo: ["/data/backups/es_backup"]    #備份目錄，根據自己情況進行填寫
systemctl restart elasticsearch.service 
mkdir -pv /data/backups/es_backup 
chmod 755 /data/backups/es_backup
chown elasticsearch:elasticsearch /data/backups/es_backup

2、創建倉庫

備份數據之前，要創建一個倉庫來保存數據，倉庫的類型支持Shared filesystem, Amazon S3, HDFS和Azure Cloud。下面以文件系統為例

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、備份索引

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

如果只想備份部分索引的話，可以加上indices 參數：

 

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

5 、查看備份信息

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

6、數據恢復

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