Control: 6.7 Ensure That Cloud SQL Database Instances Are Configured With Automated Backups

Description

It is recommended to have all SQL database instances set to enable automated backups.

Backups provide a way to restore a Cloud SQL instance to recover lost data or recover from a problem with that instance. Automated backups need to be set for any instance that contains data that should be protected from loss or damage. This recommendation is applicable for SQL Server, PostgreSql, MySql generation 1 and MySql generation 2 instances.

Remediation

From Google Cloud Console

Go to the Cloud SQL Instances page in the Google Cloud Console by visiting https://console.cloud.google.com/sql/instances.
Select the instance where the backups need to be configured.
Click Edit.
In the Backups section, check `Enable automated backups', and choose a backup window.
Click Save.

From Google Cloud CLI

List all Cloud SQL database instances using the following command:

gcloud sql instances list --format=json | jq '. | map(select(.instanceType != "READ_REPLICA_INSTANCE")) | .[].name'

NOTE: gcloud command has been added with the filter to exclude read-replicas instances, as GCP do not provide Automated Backups for read-replica instances.

Enable Automated backups for every Cloud SQL database instance using the below command:

gcloud sql instances patch <INSTANCE_NAME> --backup-start-time <[HH:MM]>

The backup-start-time parameter is specified in 24-hour time, in the UTC±00 time zone, and specifies the start of a 4-hour backup window. Backups can start any time during the backup window.

Default Value

By default, automated backups are not configured for Cloud SQL instances.

Usage

Run the control in your terminal:

powerpipe control run gcp_compliance.control.cis_v400_6_7

Snapshot and share results via Turbot Pipes:

powerpipe login
powerpipe control run gcp_compliance.control.cis_v400_6_7 --share

SQL

This control uses a named query:

select
  self_link resource,
  case
    when backup_enabled then 'ok'
    else 'alarm'
  end as status,
  case
    when backup_enabled
      then title || ' automatic backups configured.'
    else title || ' automatic backups not configured.'
  end as reason
  
  , location as location, project as project
from
  gcp_sql_database_instance;
