ECS File Backup Essential Edition provides basic backup and recovery for files on ECS instances. Each Alibaba Cloud account receives a long-term 100 GiB free quota. Usage that exceeds this quota is billed based on the total block storage capacity of your backed-up ECS instances. This topic describes the details of the free quota, its deduction rules, and how you are billed for usage that exceeds the quota.
Benefits
Free quota: 100 GiB long-term block storage backup quota.
Applicable regions: The quota is shared across all regions by an Alibaba Cloud account and all its associated RAM users under the same User ID (UID).
How to claim: You do not need to claim the quota. It is applied automatically when you use ECS File Backup Essential Edition.
Deduction rules
The free quota applies to ECS instances that have ECS File Backup Essential Edition enabled and have at least one backup version. Cloud Backup deducts the quota based on the billing order of instances. Refer to your actual bill for the specific billing order.
Billing for usage that exceeds the free quota
Cloud Backup prioritizes the free quota. After the quota is consumed, an active resource plan is applied. You can purchase a resource plan to offset costs. If both the free quota and resource plan are exhausted, you are charged on a pay-as-you-go basis. You are billed based on the total block storage capacity of the ECS instances that have backup versions.
