# 备份Elasticsearch数据
curl -XPUT 'http://localhost:9200/_snapshot/my_backup' -H "Content-Type: application/json" -d '{
"type": "fs",
"settings": {
"location": "/path/to/backup/directory",
"compress": true
},
"indices": "index_name",
"include_global_state": false
}'
# 恢复Elasticsearch数据
curl -XPOST 'http://localhost:9200/_snapshot/my_backup/snapshot_name/_restore' -H "Content-Type: application/json" -d '{
"indices": "index_name",
"include_global_state": false,
"ignore_unavailable": true,
"include_aliases": false,
"settings": {}
}'
这个例子展示了如何使用Elasticsearch的快照(snapshot)功能来备份和恢复数据。备份时,我们指定快照的名称、类型和位置,以及要备份的索引。恢复时,我们指定快照的名称和要恢复的索引。include_global_state
设置为false
意味着快照中的全局状态不会被用来恢复,这样可以防止因为全局状态不同而导致的数据问题。
