When a Data Transmission Service (DTS) instance expires or your Alibaba Cloud account has overdue payments, the instance stops running. If the issue is not resolved within 7 days, DTS releases the instance and permanently deletes all associated data.
DTS sends notifications when an instance expires or when your account has overdue payments. Renew the instance or top up your account balance promptly to avoid data loss.
