This topic describes how to enable auto-renewal for a PolarDB subscription cluster. If you have other questions about auto-renewal for your cluster, you can join DingTalk group 31840035401 to obtain technical support.
Background information
A subscription cluster has a validity period. If the cluster is not renewed before the validity period ends, service interruption or even data loss occurs. If you enable auto-renewal for your cluster, you do not need to manually renew your cluster.
Pay-as-you-go clusters do not expire. You do not need to renew pay-as-you-go clusters.
Precautions
After you enable auto-renewal for a cluster, the system automatically renews the cluster based on the subscription duration. For example, if the subscription duration of your cluster is three months and auto-renewal is enabled, you are charged for a three-month subscription each time the subscription is automatically renewed.
If you manually renew the cluster before the fees are automatically deducted, the system automatically renews the cluster before the cluster expires.
After you enable auto-renewal, it takes effect on the next day.
Fee deduction time
Fees are deducted at 08:00, nine days before the expiration time of the cluster. If the deduction fails, the system attempts to deduct fees from your account once a day until the fees are deducted or the expiration date arrives. Make sure that your Alibaba Cloud account balance is sufficient. If your cluster expires on the next day, manually renew the cluster. For more information, see Manual renewal.
