curl -XGET 'localhost:9200/_cat/indices?v&pretty'
curl -XDELETE 'localhost:9200/twitter?pretty'
Replace “twitter” with your index name.
curl -X DELETE 'http://localhost:9200/_all'
Register repo first:
curl -X PUT -u undefined:$ESPASS "localhost:9200/_snapshot/es_backup?pretty" -H 'Content-Type: application/json' -d'
{
"type": "fs",
"settings": {
"location": "es_backup"
}
}
'
Instead of creating new repo, you can use the default_backup repo if you want.
Create first backup
curl -X PUT "localhost:9200/_snapshot/es_backup/ztest?wait_for_completion=true&pretty"
To create single index snapshot use
curl -X PUT "localhost:9200/_snapshot/default_backup/myindex_backup?wait_for_completion=true&pretty" -H 'Content-Type: application/json' -d'
{
"indices": "coolindex"
}'
The backup folder is created in /opt/backup/elasticsearch/.
You can now zip this and transfer to another server.
curl -s -X GET "localhost:9200/_snapshot" curl -s -X GET "localhost:9200/_snapshot/es_backup/*?pretty=true"
If you have an archive, unarchive it to /opt/backup/elasticsearch/, e.g.
tar xvf /tmp/es_backup.tar.gz -C /opt/backup/elasticsearch/es_backup
When you transfer it to another server unzip it, make sure that the owner is elasticsearch on the folder and then create the snapshot repository with command above, otherwise you won't see it when trying to list the snaphots.
List the snapshots with above command.
After this do the restore with snapshot name you want:
curl -s -X POST "localhost:9200/_snapshot/es_backup/snapshot-12/_restore"
To restore single index use
curl -s -X POST "localhost:9200/_snapshot/myes_bak/snapshot-2023-01-11/_restore" -H 'Content-Type: application/json' -d'
{
"indices": "niceindex"
}'
If you get an error that an index exist, like with the system index .geoip_databases, you can restore the system indices from the snapshot as well with
curl -s -X POST "localhost:9200/_snapshot/es_backup/snapshot-12/_restore" -H 'Content-Type: application/json' -d \
'{
"include_global_state": true
}'
