## Create snapshot
Creates a snapshot within an existing repository.
* To learn more about snapshots, see [Snapshots]({{site.url}}{{site.baseurl}}/opensearch/snapshots/index).
* To view a list of your repositories, see [Get snapshot repository]({{site.url}}{{site.baseurl}}/api-reference/snapshots/get-snapshot-repository).
### Path and HTTP methods
```json
PUT /_snapshot/<repository>/<snapshot>
POST /_snapshot/<repository>/<snapshot>
```
### Path parameters
Parameter | Data type | Description
:--- | :--- | :---
repository | String | Repostory name to contain the snapshot. |
snapshot | String | Name of Snapshot to create. |
### Query parameters
Parameter | Data type | Description
:--- | :--- | :---
wait_for_completion | Boolean | Whether to wait for snapshot creation to complete before continuing. If you include this parameter, the snapshot definition is returned after completion. |
### Request fields
The request body is optional.
Field | Data type | Description
:--- | :--- | :---
`indices` | String | The indices you want to include in the snapshot. You can use `,` to create a list of indices, `*` to specify an index pattern, and `-` to exclude certain indices. Don't put spaces between items. Default is all indices.
`ignore_unavailable` | Boolean | If an index from the `indices` list doesn't exist, whether to ignore it rather than fail the snapshot. Default is false.
`include_global_state` | Boolean | Whether to include cluster state in the snapshot. Default is true.
`partial` | Boolean | Whether to allow partial snapshots. Default is false, which fails the entire snapshot if one or more shards fails to stor
#### Example requests
##### Request without a body
The following request creates a snapshot called `my-first-snapshot` in an S3 repository called `my-s3-repository`. A request body is not included because it is optional.
```json
POST _snapshot/my-s3-repository/my-first-snapshot
```
{% include copy-curl.html %}
##### Request with a body
You can also add a request body to include or exclude certain indices or specify other settings:
```json
PUT _snapshot/my-s3-repository/2
{
"indices": "opensearch-dashboards*,my-index*,-my-index-2016",
"ignore_unavailable": true,
"include_global_state": false,
"partial": false
}
```
{% include copy-curl.html %}
#### Example responses
Upon success, the response content depends on whether you include the `wait_for_completion` query parameter.
##### `wait_for_completion` not included
```json
{
"accepted": true
}
```
To verify that the snapshot was created, use the [Get snapshot]({{site.url}}{{site.baseurl}}/api-reference/snapshots/get-snapshot) API, passing the snapshot name as the `snapshot` path parameter.
{: .note}
##### `wait_for_completion` included
The snapshot definition is returned.
