ElasticSearch 快照/备份不起作用

Question

我的 ES 快照不起作用或看起来是空的。

首先，我在我的 Ubuntu 服务器上做了这个:

1.创建备份目录

mkdir /home/admin/dumps/elasticsearch

2. 将此目录设置为 elatissearch.yml 用于快照

path.repo: ["/home/admin/dumps/elasticsearch"]

3.设置快照存储库位置

curl -XPUT 'http://localhost:9200/_snapshot/backup' -d '{
  "type": "fs",
  "settings": {
    "location": "/home/admin/dumps/elasticsearch",
    "compress": true
  }
}'

然后，我可以运行快照:

curl -XPUT localhost:9200/_snapshot/backup/elasticsearch_snapshot?wait_for_completion=true

回复:

{"snapshot":{"snapshot":"elasticsearch_snapshot","version_id":2030099,"version":"2.3.0","indices":["references"],"state":"SUCCESS","start_time":"2016-04-08T08:45:30.525Z","start_time_in_millis":1460105130525,"end_time":"2016-04-08T08:45:30.779Z","end_time_in_millis":1460105130779,"duration_in_millis":254,"failures":[],"shards":{"total":15,"failed":0,"successful":15}}}

我还创建了一个 cronjob 来在每天 5:35 备份 ElasticSearch:

35 5 * * * curl -X PUT "localhost:9200/_snapshot/backup/elasticsearch.$(date +\%Y-\%m-\%d)?wait_for_completion=true"

好吧，当我转到我的 dumps/elasticsearch 文件夹时，我得到了:

Cron 快照在那里，但所有数据似乎都是空的!
我错过了什么 ？

Answer 1

在 elasticsearch 快照中，只有快照的元数据存储在根级路径上。
所有索引备份实际数据存储在/indices下根路径下的文件夹。
如果你看看里面 /indices文件夹，您将看到您的集群数据
