After a subscription PolarDB-X instance expires, it cannot run as expected. If you want to continue using the instance, you must renew the instance within a specific period of time. Otherwise, CPU, memory, and disk resources in the instance are automatically released and data loss occurs. Pay-as-you-go PolarDB-X instances do not expire and thus do not require renewal.
Alibaba Cloud sends notifications to you before your subscription PolarDB-X instance expires. To avoid business interruptions, we recommend that you renew your subscription PolarDB-X instance at your earliest opportunity.
Renewal methods
You can manually renew or enable auto-renewal for your PolarDB-X instance. The cost of renewing a subscription PolarDB-X instance is the same as purchasing a new subscription.
Auto-renewal
PolarDB-X provides the auto-renewal feature.
After you enable auto-renewal, the system first attempts to deduct fees from your Alibaba Cloud account at 08:00:00 on the ninth day before the instance expires. If the first attempt to deduct fees fails, the system attempts to deduct fees from your Alibaba Cloud account every day for the next two days. In total, up to three attempts to deduct fees are made. Make sure that your Alibaba Cloud account has sufficient balance.
If all of the three automatic fee deduction attempts fail, you must manually renew your subscription PolarDB-X instance before the instance expires. This prevents instance downtime that may cause data loss.
Manual renewal
After a subscription PolarDB-X instance expires, the system retains your instance for a few days before the instance is released. You can manually renew the instance within this period of time. After you perform the manual renewal operation, fees are immediately deducted from your Alibaba Cloud account.
