Billing Standards

Pricing varies by region and disk type. For more information, see Price Overview.

Snapshot Billing Overview

Snapshot service was commercialized on January 22, 2019 at 00:00:00. All snapshots are billed based on the storage usage.
Note:
Images use the CBS snapshot service for data storage. As a result, retaining custom images occupies a certain portion of your snapshot capacity and incurs costs.

Billing Mode

You are charged according to the total storage size of your snapshots. Each region is charged separately. CBS is pay-as-you-go on an hourly billing cycle.
Note:
To view the size of your snapshots in each region, go to the Snapshot console.

Billing Standards

Pricing for snapshots varies by region. For more information, see Price Overview.

Free Tier

After the commercialization of snapshots, Tencent Cloud still provides users with a free tier of 80 GB in regions in China. The part beyond the free tier is postpaid on an hourly basis. For billing standards, see Price Overview. Note the following:
The free tier is available to users in regions as listed in the Snapshot console.
The free snapshot tier will be canceled in the future. For more information, check the CBS product page regularly.
The following table describes how snapshot storage is billed under different circumstance:
