1. Open the GCP console and navigate to the Cloud SQL instances page.
2. Select the instance for which you want to configure the backup retention policy.
3. Click on the “Edit” button at the top of the page.
4. In the “Backup” section, scroll down to the “Retention” field.
5. Set the “Minimum number of backups to be retained” to the desired value. It is recommended to retain at least 7 backups.
6. Click on the “Save” button to apply the changes.
7. Verify that the backup retention policy has been updated by checking the “Backups” tab for the instance.

​

1. Open the Cloud Shell in GCP Console.
2. Run the following command to list all the available Cloud SQL instances:

gcloud sql instances list

3. Choose the instance for which you want to remediate the misconfiguration.
4. Run the following command to set the minimum number of backups to be retained:

gcloud sql instances patch [INSTANCE_NAME] --backup-retention-window [NUMBER_OF_DAYS]

gcloud sql instances patch my-instance --backup-retention-window 7

5. Verify that the configuration has been updated by running the following command:

gcloud sql instances describe [INSTANCE_NAME]

1. First, we need to install the required libraries. Open the command prompt and run the following command:
   Copy

   pip install google-cloud-storage google-auth google-auth-oauthlib google-auth-httplib2 google-cloud-sql
   

2. Next, we need to authenticate ourselves with the GCP project. For this, we need to create a service account and download the JSON key file. Follow the instructions given in the link to create a service account: https://cloud.google.com/iam/docs/creating-managing-service-accounts
3. Once the service account is created, download the JSON key file and set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the JSON key file.

   export GOOGLE_APPLICATION_CREDENTIALS="/path/to/key.json"
   

4. Now, we can write a Python script to remediate the misconfiguration. Here is a sample script to set the minimum number of backups to be retained to 7:

   from google.oauth2 import service_account
   from google.cloud import sql_v1beta4
   from google.cloud.sql_v1beta4.services.sql_backup_runs_service import SqlBackupRunsServiceClient
   
   # Authenticate with GCP using the service account key file
   credentials = service_account.Credentials.from_service_account_file('/path/to/key.json')
   
   # Set the project ID and instance name
   project_id = 'project-id'
   instance_name = 'instance-name'
   
   # Set the minimum number of backups to be retained
   retention_count = 7
   
   # Create a client object for the SQL Backup Runs API
   backup_runs_client = SqlBackupRunsServiceClient(credentials=credentials)
   
   # Get the latest backup run for the instance
   backup_runs = backup_runs_client.list(project=project_id, instance=instance_name).items
   latest_backup_run = sorted(backup_runs, key=lambda x: x.end_time, reverse=True)[0]
   
   # Set the retention policy for the latest backup run
   retention_policy = sql_v1beta4.types.BackupRetentionSettings(retention_unit='COUNT', retention_count=retention_count)
   backup_runs_client.update(project=project_id, instance=instance_name, id=latest_backup_run.id, body={'settings': {'backupRetentionSettings': retention_policy}})
   

   Replace project-id, instance-name, and /path/to/key.json with the appropriate values.
5. Save the script with a .py extension and run it using the following command:
   Copy

   Ask AI

   python script_name.py
   

6. After running the script, the minimum number of backups to be retained for the SQL database will be set to the specified value.
