When a log analysis instance expires, the instance no longer stores new logs. All stored logs are retained for seven days. When the retention period elapses, all logs are deleted and cannot be recovered. To prevent the issues that are related to an expired log analysis instance, we recommend that you pay attention to the expiration time of the instance and renew the instance at the earliest opportunity, or enable auto-renewal.
