Application Scenarios

A snapshot is a full or incremental backup of a GaussDB(DWS) cluster at a specific point in time. It records the current database data and cluster information, including the number of nodes, node specifications, and database administrator name.

After a cluster is created, automated snapshots are enabled by default. If automated snapshots are enabled for a cluster, GaussDB(DWS) periodically takes snapshots of that cluster based on the time and interval you set. The default setting is every eight hours an incremental backup and a full backup once a week. You can configure one or more automated snapshot policies for the cluster as required.

Solution

Automated snapshots are enabled by default and cannot be manually deleted. Therefore, the evaluation result of this policy is always compliant.

Rule Logic

If automated snapshots are not enabled for a GaussDB(DWS) cluster, this cluster is non-compliant.
If automated snapshots are enabled for a GaussDB(DWS) cluster, this cluster is compliant.
