FAQs About ECS Frozen, Deletion, and Unsubscription

Why Are My ECSs Released?

After you purchase ECSs on Huawei Cloud but you do not complete the payment or renewal, the purchased ECSs will enter a grace period. If you still do not complete the payment or renewal after the grace period is ended, your ECS will enter a retention period. The ECS cannot provide services during the retention period. If you still do not complete the payment or renewal after the retention period is ended, your data stored in the ECS will be deleted and the ECS will be released. For details, see Resource Suspension and Release.

Can I Back Up My Data on the ECS When It Is Frozen?

No. If your ECS is frozen due to arrears, you can back up data only after you top up your account.

How Do I Unfreeze a Frozen ECS?

• Frozen due to arrears: You can renew or top up your account to unfreeze your ECS. You can renew or delete the ECSs that are frozen due to arrears. Only yearly/monthly ECSs that have not expired can be unsubscribed.
• Frozen due to violation detected by HUAWEI CLOUD: You can renew or delete such ECSs. Only yearly/monthly ECSs that have not expired can be unsubscribed.
• Frozen due to violation detected by the public security department: You can renew such ECSs, but cannot delete them. Such frozen ECSs cannot be unsubscribed although they are displayed on the unsubscription page.

What Is the Impact on Services When Resources Are Frozen, Unfrozen, or Released?

• When resources are frozen, resource access and usage are restricted, which will interrupt your services. For example, if a server is frozen, it will be automatically stopped.
• When resources are unfrozen, restrictions on resources are removed, but you need to check and restore your services. For example, after a yearly/monthly ECS is unfrozen, it will be automatically started. After a pay-per-use ECS is unfrozen, you need to start it manually.
• When resources are released, data stored on the resources will be deleted and cannot be retrieved.

How Do I Renew an ECS?

After an ECS billed on a yearly/monthly basis expires, renew it on the Renewals page of the management console. For details, see Renewal Management.

How Do I Restore an Unsubscribed or Deleted ECS?

After an unsubscription is complete, the ECS will be permanently deleted and cannot be restored. You are advised to purchase a new ECS if you still want to use ECSs.

How Do I Delete an ECS?

• Pay-per-use ECS: On the ECS list page, select the target ECS, click More in the Operation column, and choose Delete.
  • Read details about deleting ECSs carefully.
  • Choose to delete the unneeded EIP and attached data disks together with the ECS to avoid generating costs.

How Do I Configure CBR and HSS for My ECS?

You can choose to purchase CBR and HSS together with your ECSs during the purchase process. They are not configured by default.

You can view the backup policy on the CBR console and associate the policy with your ECS. HSS takes effect only after the agent is installed on an ECS.
