Cloud Backup:Billing methods and billable items

Last Updated:Oct 21, 2025

This topic describes the billing methods, pricing, billable items for various features and data sources, for Cloud Backup.

Important

Activating Cloud Backup is free. However, you are charged for using Cloud Backup features.

Billing methods

Cloud Backup supports the subscription (resource plan) and pay-as-you-go billing methods for most of its features and billable items. For more information, see the following table. The ECS Backup Essential Edition supports only the subscription billing method.

Billing method

Description

Pay-as-you-go

  • Pay after you use the service.

  • Bills for standard backup features are generated hourly. Bills for ECS File Backup Essential Edition are generated daily. Fees are settled monthly.

  • The pay-as-you-go billing method is used by default when you activate the service. To use the subscription billing method, purchase a resource plan.

Subscription (resource plan)

  • Pay upfront. This method is more cost-effective than pay-as-you-go.

  • You can use multiple resource plans at the same time.

  • Fees are deducted from your resource plan. After the plan expires, the billing method automatically changes to pay-as-you-go.

Note
  • Resource plans take effect immediately after purchase and are non-refundable.

  • Resources that exceed the quota of your resource plan are billed on a pay-as-you-go basis.

Subscription

This billing method applies only to ECS Backup Essential Edition. Purchase a subscription instance before you use the service.

Pricing

Pricing is the same across all regions. If you can use subscription resource plans to offset fees, we recommend that you purchase them first. For specific prices, see Pricing.

Billable features

Overview of billable features

Cloud Backup offers different billing methods for its standard backup, ECS Backup Essential Edition, and ECS File Backup Essential Edition features. The following table describes the differences in billable items.

Billing component

Billable item

Description

Billing categories for standard backup features

  • Backup fees: software usage fee and storage usage fee

  • Database Backup fees: repository rental fee and storage usage fee

  • Traffic fees: outbound traffic fee, cross-region replication traffic fee for backup vaults, and cross-region replication traffic fee for disaster recovery

The basic billable items for Cloud Backup consist of four categories: backup fees, database backup fees and traffic fees.

Billable items vary based on the billing component. You are charged for the billable items that correspond to the basic backup features you use.

Billing for ECS Backup Essential Edition

ECS Backup Essential Edition subscription instance

You must purchase an ECS Backup Essential Edition subscription instance in advance. The ECS Backup Essential Edition uses a subscription billing method and charges you based on the number of instances.

Note

To use ECS instance backup, you must also activate the snapshot service. The capacity used by the ECS instance backup feature does not count toward the total data volume limit of the protected ECS instance. Cloud Backup does not charge software usage or storage fees. However, the ECS service charges snapshot fees. For more information about billing, see ECS snapshot billing overview.

Billing for ECS File Backup Essential Edition

Fees are calculated based on the total capacity of block storage attached to the backed up ECS instance. Each Alibaba Cloud account (UID) and its RAM users share a free quota of 100 GiB across all regions.

Fees are calculated based on the total capacity of block storage attached to the backed up ECS instance, regardless of the actual amount of file data on the instance.

Note

The total block storage capacity is calculated based on the latest backup that is completed before 00:00 (UTC+8).

Note

To avoid duplicate charges, select only one backup plan for each data source.

  • For ECS file backup, you can choose only one of the following options: ECS File Backup Essential Edition, file backup in ECS Backup Essential Edition, or ECS File Backup in standard backup features.

  • For ECS database backup, you can choose either database backup in ECS Backup Essential Edition or ECS database backup in standard backup features.

  • For ECS instance backup, you can choose either instance backup in ECS Backup Essential Edition or instance backup in standard backup features.

Billing categories for standard backup features

The billable items for the standard backup features of Cloud Backup consist of four categories: backup fees, database backup fees and traffic fees.

The following table describes the billable items.
