Hi Team,

I am trying to take snapshot without replication by setting **index.number\_of\_replicas as "0"**

POST /\_snapshot/backup/snapshot\_chr1  
{  
"indices": "es\_chr",  
"ignore\_unavailable": "true",  
"include\_global\_state": false,  
"index\_settings": {  
"index.number\_of\_replicas": 0  
}  
}

But I am getting an error and is shown as below,

{  
**"error": "SnapshotCreationException[[backup:snapshot\_chr1] failed to create snapshot]; nested: IOException[Stream Closed]; ",**  
\*\* "status": 500\*\*

}

Is it possible to do in elasticsearch?

Please guide us and it would be very helpful.

Thanks in Advance.

Regards,  
Ganeshbabu R

Setting replicas is only valid during a restore - [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-snapshots.html#\_changing\_index\_settings\_during\_restore](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-snapshots.html#_changing_index_settings_during_restore)

Hi @warkolm,

We have a clarification in taking a snapshot for an index. We have an index

![](https://us1.discourse-cdn.com/elastic/original/2X/a/a5bc5a71a1eb3dca5073f9d5258b0371f9aabdeb.png)

**We need to know whether taking snapshot with 2 replicas is a good practice?**

If you see the primary size of index 1.5 TB without replica and with 2 replicas the overall size of the index would be around 4.5 TB. Suppose if I take snapshot of item index with 2 replica then the snapshot size would be in the range 4.0 to 4.5 TB

Every day we plan to take incremental snapshot and I can say changes will be updated in the item index and size of the index grows simultaneously.

Please let us know your feedback.

**Note:- How much storage space required for taking snapshot?**

Snapshot only applies to primaries, when we restore we recreate the replicas based off those primaries.
