Yearly/Monthly Billing

Application Scenarios

If you want to ensure resource stability over a certain period of time, yearly/monthly billing is a good choice for the following types of workloads:

• Long-term workloads with stable resource requirements, such as official websites, online malls, and blogs.
• Long-term projects, such as scientific research projects and large-scale events.
• Workloads with predictable traffic bursts, for example, e-commerce promotions or festivals.
• Workloads with high data security requirements

Billed Items

Yearly/Monthly CBR resources are billed based on the purchased duration. Any operations performed on the CBR resources will not affect their yearly/monthly charges. You are billed for the following items on a yearly/monthly basis.

Billed Usage Period

A yearly/monthly CBR resource is billed for the purchased duration. The billing starts from when you activated or renewed the subscription, and ends at 23:59:59 of the expiry date.

For example, if you purchased a one-month server backup vault on March 8, 2023, 15:50:04, the billed usage period was from March 8, 2023, 15:50:04 to April 8, 2023, 23:59:59.

Billing Examples

Suppose you purchased a 100-GB server backup vault for a month on March 8, 2023, 15:50:04, and renewed the subscription for one more month before the initial subscription expired. The following usage periods would be billed.

The preceding prices are for reference only. For details, see CBR Pricing Details.

Price Change After Specification Change

If the specifications of a yearly/monthly CBR resource no longer meet your needs, you can change the specifications on the console. The system will recalculate the price and either bill or refund you the difference.

• If you upgrade your resource specifications, you need to pay the difference in price.
• If you downgrade your resource specifications, Huawei Cloud will refund you the difference.

Suppose you purchased a 100-GB server backup vault for a month on April 8, 2023 and expanded the vault capacity to 200 GB on April 18, 2023. The price of the original specifications was $20 USD/month, and that for the new specifications was $40 USD/month. The price difference will be calculated as follows:

Price difference for the specification upgrade = Price for the new specifications × Remaining period - Price for the original specifications × Remaining period

The remaining period is the remaining days of each calendar month divided by the maximum number of days in each calendar month.

In this example, Remaining period = 12 (Remaining days in April)/30 (Maximum number of days in April) + 8 (Remaining days in May)/31 (Maximum number of days in May) = 0.6581.

Cost of upgrade = $40 USD x 0.6581 - $20 USD x 0.6581 = $13.162 USD

Impact of Expiration

Figure 1 shows the statuses a yearly/monthly CBR resource can go through throughout its lifecycle. After a CBR resource is purchased, it enters the valid period and works normally during this period. If the resource is not renewed after it expires, before being deleted, it first enters a grace period and then a retention period.

Expiration Reminder

The system will send you a reminder (by email, SMS, or in-app message) 7 days before a yearly/monthly CBR resource expires to remind you to renew the subscription.

Impact of Expiration

If your yearly/monthly CBR resource is not renewed after it expires, it changes to the Expired state and enters a grace period.

If the yearly/monthly CBR resource is not renewed after the grace period ends, its status turns to Frozen and it enters a retention period. You cannot perform any operations on the resource while it is in the retention period.

If the yearly/monthly CBR resource is not renewed by the time the retention period ends, the resource will be released and data cannot be restored.
