Querying the Automatic Snapshot Creation Policy
Function
The snapshot backup function of CSS provides data protection and restoration capabilities for Elasticsearch/OpenSearch clusters. Through snapshot backup, the data status of a cluster can be saved to an OBS bucket for restoration when needed. Cluster snapshots are classified into two types: automatic snapshots and manual snapshots. This API is used to query the automatic snapshot creation policy.
-
Automatic snapshot: Automatically executes snapshot backup operations based on preset time policies, suitable for periodic backup scenarios, such as daily or weekly backups, to ensure continuous data protection. By configuring automatic snapshot policies, you can reduce manual operations and improve backup reliability and efficiency.
-
Manual snapshot: Manually triggers snapshot backup operations based on user requirements, suitable for temporary backups or specific scenarios, such as backing up before major operations (for example, cluster upgrade) so that you can quickly restore to the previous state if a problem occurs. Manual snapshots provide higher flexibility, allowing you to create snapshots at any time as needed.
Calling Method
For details, see Calling APIs.
Authorization Information
Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.
- If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
- If you are using identity policy-based authorization, the following identity policy-based permissions are required.
