    Backup storage

    Backup storage for PolarDB for MySQL edge clusters is currently free of charge.

    Expiration

    To avoid service interruptions, manually renew your PolarDB for MySQL edge cluster or enable auto-renewal before it expires.

    Billing details

    How to recover the cluster

    On the expiration date

    The cluster is shut down, locked, and inaccessible.

    Compute nodes, storage space, and backup storage: No fees are charged.

    To unlock the cluster, manually renew it.

    8 days after expiration (7 days after shutdown)

    The cluster is released.

    Note

    Alibaba Cloud sends you a reminder by text message or email one day before the cluster is released.

    After the cluster is released, the data retention policy is as follows:

    • If your cluster's backup policy is set to Retain This Backup Set For Long-term (a Full Backup Is Performed Before Release) or Retain All Backup Sets For Long-term, the data is moved to the cluster recycle bin and you are charged accordingly.

    • If your cluster's backup policy is set to Delete All Backup Sets Immediately, the cluster is permanently released. The data is not retained and cannot be recovered. No fees are charged.

    If a released cluster is in the cluster recycle bin, you can restore the cluster from its backup sets.

    Renewal

    Subscription clusters have an expiration date. If you do not renew a cluster before it expires, you may experience service interruptions or data loss. To continue using the cluster, you must renew it before it expires.

    Notes

    Description

    Auto-renewal

    • 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.

    • The renewal fee is deducted at 08:00 three days before the expiration date of the cluster. If the deduction fails, the system attempts to deduct the renewal fee one day before the expiration date, on the expiration date, six days after the expiration date, and 14 days after the expiration date. Make sure that the balance of your Alibaba Cloud account is sufficient.

    • If you manually renew your cluster before the renewal fee is automatically deducted, the system calculates the next auto-renewal date based on the new expiration date.

    • Auto-renewal takes effect the next day after you enable it.

    Manual renewal

    • Before a cluster expires, you can manually renew it to ensure service continuity.

    • If you want to use a cluster that has expired, you can manually renew it before it is released.

    Auto-renewal

    Enable auto-renewal

    • Select Auto-renewal when you purchase a subscription cluster.

      image

    • Go to the Expenses and Costs > Renewal page. On the Manual or Nonrenewal tab, find the cluster for which you want to enable auto-renewal and click Renew in the Actions column.

      Note

      If you cannot find the cluster, auto-renewal may already be enabled for the cluster. Check whether the cluster is on the Auto tab.

    Change the auto-renewal cycle

    Go to the Expenses and Costs > Renewal page. On the Auto tab, find the cluster that you want to manage and click Edit Auto Renewal in the Actions column.

    Disable auto-renewal

    Go to the Expenses and Costs > Renewal page. On the Auto tab, find the cluster that you want to manage and click Enable Manual Renewal in the Actions column.

    Manual renewal

    • Go to the PolarDB for ENS console. Find the target cluster and in the Actions column, choose More > Renew.

    • You can go to the Expenses and Costs > Renewal page. On the Manual, Auto, or Nonrenewal tab, find the cluster that you want to renew and click Renew in the Actions column.
