+# Snapshot Actions
+In this guide, we will look at some snapshot actions that allow you to manage and work with snapshots of your indices.
+
+
+## Setup
+Let's create a client instance, and an index named `movies`:
+```python
+from opensearchpy import OpenSearch
+
+host = 'localhost'
+port = 9200
+auth = ('admin', 'admin') # For testing only. Don't store credentials in code.
+
+client = OpenSearch(
+    hosts = [{'host': host, 'port': port}],
+    http_auth = auth,
+    use_ssl = True,
+    verify_certs = False,
+    ssl_show_warn = False
+)
+
+print(client.info())  # Check server info and make sure the client is connected
+client.indices.create(index='movies')
+```
+## API Actions
+### Create Snapshot Repository
+Before taking a snapshot, you need to create a snapshot repository to store the snapshots. You can use the `create_repository` API action for this purpose. The following example creates a snapshot repository named `my_repository`:
+
+```python
+repo_body = {
+    "type": "fs",  # Replace 'fs' with the appropriate repository type
+    "settings": {
+        "location": "/path/to/repo", 
+    }
+}
+
+# Create the snapshot repository and capture the response
+response = client.snapshot.create_repository(repository='my_repository', body=repo_body)
+
+# Print the response to see the result
+print(response)
+```
+
+### Create Snapshot
+To create a snapshot of an index, you can use the `create` method from the `snapshot` API. The following example creates a snapshot named `my_snapshot` for the movies index:
+
+```python
+client.snapshot.create(repository='my_repository', snapshot='my_snapshot', body={"indices": "movies"})
+```
+
+### Verify Snapshot Repository
+The `verify_repository` API action allows you to verify a snapshot repository. Verifying a repository ensures that it is accessible and operational, but it does not validate the integrity of the snapshots stored within the repository. The following example verifies `my_repository`:
+
+```python
+response = client.snapshot.verify_repository(repository='my_repository')
+
+# Print the HTTP status code
+print("HTTP Status Code:", response.status_code)
+
+# Print the response content
+print("Response Content:", response.content)
+```
+
+### Delete Snapshot
+To delete a specific snapshot, use the `delete` API action:
+
+```python
+client.snapshot.delete(repository='my_repository', snapshot='my_snapshot')
+```
+### Restore Snapshot
+To restore a snapshot and recreate the indices, mappings, and data, you can use the `restore` method. The following example restores the `my_snapshot` snapshot:
+
+```python
+response = client.snapshot.restore(repository='my_repository', snapshot='my_snapshot')
+```
+
+### Get Snapshot Status
+To check the status of a snapshot, you can use the `status` method.
+
+```python
+response = client.snapshot.status(repository='my_repository', snapshot='my_snapshot')
+```
+
+### Clone Snapshot
+You can clone an existing snapshot to create a new snapshot with the same contents. The `clone` operation allows you to create multiple copies of a snapshot, which can be useful for backup retention or creating snapshots for different purposes. The following example clones a snapshot named `my_snapshot` to create a new snapshot named `my_snapshot_clone`:
+
+```python
+client.snapshot.clone(
+    repository='my_repository',
+    snapshot='my_snapshot',
+    target_snapshot='my_snapshot_clone'
+)
+```
+## Get Snapshot
+To retrieve information about a specific snapshot, you can use the `get` API action. It provides metadata such as the snapshot's status, indices included in the snapshot, and the timestamp when the snapshot was taken. The following example retrieves information about the `my_snapshot`:
+
+```python
+response = client.snapshot.get(
+    repository='my_repository',
+    snapshot='my_snapshot'
+)
+
+# Print the response to see the result
+print(response)
+```
+
+## Get Repository
+To retrieve information about a snapshot repository, you can use the `get_repository` API action. It provides details about the configured repository, including its type and settings. The following example retrieves information about the `my_repository`:
+
+```python
+response = client.snapshot.get_repository(repository='my_repository')
+```
+
+## Repository Analyze
+The `repository_analyze` API action allows you to analyze a snapshot repository for correctness and performance. It checks for any inconsistencies or corruption in the repository. The following example performs a repository analysis on `my_repository`:
+
+```python
+response = client.snapshot.repository_analyze(repository='my_repository')
+```
+
+## Cleanup
+
+Finally, let's delete the `movies` index and clean up all the snapshots and the repository:
+```python
+client.indices.delete(index='movies')
+client.snapshot.delete(repository='my_repository', snapshot='my_snapshot')
+client.snapshot.delete_repository(repository='my_repository')
+```
