To ensure that your organization’s record data is retained for at least seven years in Cloud Storage, you need to apply a retention policy and enable bucket lock. This prevents the policy from being altered or the data from being deleted before the retention period ends.

Identify Buckets: Determine which Cloud Storage buckets contain the record data that needs to be retained.

Apply Retention Policy:

Go to the Google Cloud Console and navigate to "Cloud Storage".

Select the bucket you identified.

Go to the "Retention" tab and set a retention policy to retain objects for seven years.

Enable Bucket Lock:

Once the retention policy is set, you need to lock the bucket to make the retention policy permanent.

This is done by enabling the bucket lock. Go to the "Retention" tab and click "Lock".

Confirm and Monitor:

Confirm that the bucket lock is applied.

Monitor the bucket using log-based alerts to ensure compliance.
