elasticsearchHow do I backup an Elasticsearch index to a file?
Using the Elasticsearch snapshot and restore API, you can easily backup an Elasticsearch index to a file. The snapshot API allows you to take a backup of a cluster, a single index, or even multiple indices.
For example, to backup an index named my-index
to a file, you can use the following API call:
PUT /_snapshot/my-backup/my-index-backup?wait_for_completion=true
{
"indices": "my-index"
}
This will create a snapshot named my-index-backup
in the repository my-backup
. The wait_for_completion
parameter ensures that the API call will wait until the snapshot is completed before returning.
To restore the index, you can use the following API call:
POST /_snapshot/my-backup/my-index-backup/_restore
This will restore the snapshot my-index-backup
from the repository my-backup
.
