es的备份与恢复

指定index进行备份

• 设置备份保存路径。如下设置备份文件夹名为graph_backup，存储文件路径/data/duser/industry_es_backup

PUT /_snapshot/my_backup
{
  "type": "fs",
  "settings": {
    "location": "/data/duser/industry_es_backup"
  }
}

• 指定index进行备份

PUT /_snapshot/my_backup/snapshot_graph
{
  "indices": "devjanus_qiye_mixedcodeqiye1607495310,devjanus_renwu_mixedcoderenwu1607485038,devjanus_industry_supply_chain_1130_mixedcodeindustry_supply_chain_11301606705883"
}

快照恢复

• 1. 创建设置快照文件夹

curl -XPUT -u username:password
"http://host:9200/_snapshot/my_backup" -H 'Content-Type:
application/json' -d '
{
 "type": "fs",
 "settings": {
 "location": "/data/duser/preprocess/es"
 }
}

• 2. 将生成的快照压缩文件夹进行解压

• 3. 进行相关快照恢复,并重命名指定index

## 如下修改前缀
POST /_snapshot/my_backup/snapshot_graph/_restore
{
 "indices":
"devjanus_qiye_mixedcodeqiye1607495310,devjanus_renwu_mixedcoderenwu1607485
038,devjanus_industry_supply_chain_1130_mixedcodeindustry_supply_chain_1130
1606705883",
 "rename_pattern": "devjanus_(.+)",
 "rename_replacement": "a_zc_$1"
}

## 如下也是替换前缀

POST /_snapshot/my_backup/snapshot_industry/_restore
{
 "indices":
"industry_company_v1,industry_v2,main_product_cal_v6,product_v2,company_finance
_cal_v4",
 "rename_pattern": "(.+)_v[0-9]",
