Restore in Elasticsearch

What it is

In Elasticsearch, restore refers to a snapshot restore mechanism. A snapshot restore can be carried out once you have already set up the snapshot repository and have taken the snapshot. You can restore the entire cluster from the snapshot or restore an individual index or selected indices.

Examples

To restore the whole snapshot :

POST /_snapshot/my_backup/snapshot-01-11-2019/_restore

To restore an individual index :

POST /_snapshot/my_backup/snapshot-01-11-2019/_restore
{
  "indices": "my_index"
}
Notes
  • The snapshot restore capability must be enabled in elasticsearch.yml in case you are using security tools like Searchguard. Otherwise, it will throw a security exception.
Common Problems:
  • If an index or indices already exist with the same names as those you are going to restore, they need to either be closed or deleted before you can restore from a snapshot. Otherwise, the restore operation will fail due to an error that the index already exists.
