Hello, I encountered an issue during a datastream restore this morning:

_What I want to achieve:_

- restore the backuped indices from may 2023 in the same current working datastream ; I would like to avoid interruption of service as the dataflow are bulking continuously into the datastream.

_The behaviour I observed:_

- restoring the latest may 2023 snapshot **overwrite the current datastream**
- it does not break the data indexation, but redirect the flow not in a july (date of the day) indices BUT in a old 31th of may indices.
- all indices starting from june until today are still present on the cluster **BUT NOT LINKED** to the datastream anymore 😕 and therefore not searchable in kibana discover section

**How can I fix this situation?**

Thanks in advance for your time and help.

kr,

ps: the procedure I followed:

- [Restore a managed data stream or index | Elasticsearch Guide [8.8] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/index-lifecycle-and-snapshots.html)
- restore from the kibana UI, selecting only the datastream I would like to restore -\> didn't expect that will overwrite the current one 😕 ; Do I have to select, unselect or specify a particular parameters to achive this ?

nb: related topcis:

In order to fix the no more linked indices, we can use the api:

```auto
POST _data_stream/_modify
{
  "actions": [
  
    {
      "add_backing_index": {
        "data_stream": "lyourdsnamehere-default",
        "index": ".ds-logs-yourdsnamehere-2023.06.02-000085"
      }
    }
  ]
}

```

BUT I still wondering what is the best approach to restore old index of a datastream into the datastream without breaking anything 😕
