Billing

Billing Items of SFS Turbo

The default billing mode is pay-per-use. With this billing mode, you are billed based on the storage capacity that you select (instead of the used capacity) and the amount of time that you use the capacity. Usage duration is calculated at the top of every hour. A duration of less than one hour is rounded up to an hour. For details about SFS billing, see Table 1.

Billing Modes

SFS supports the following billing modes: pay-per-use and yearly/monthly. For details about how to purchase SFS, see How Do I Purchase SFS?

Changing Billing Mode

• Yearly/monthly is a prepaid billing mode. You will be billed based on the subscription duration you specify. This mode provides a favorable price and is ideal when the resource use duration is predictable.
• Pay-per-use is a postpaid billing mode. You will be billed based on the billing items of specific file systems and can purchase or delete file systems at any time. Fees are deducted from the account balance.

In some regions, you can change the billing mode of an SFS Turbo file system from pay-per-use to yearly/monthly. For details, see Yearly/Monthly Subscription. Currently, the billing mode cannot be changed from yearly/monthly to pay-per-use.

Expiration

After a yearly/monthly SFS Turbo file system expires, the system will not automatically change it to pay-per-use billing, but processes it based on the rules specified in Resource Suspension and Release. If the file system is not renewed before the retention period expires, it will be deleted.

Overdue Payment

Possible causes of overdue payment:

• You have purchased an SFS Capacity-Oriented resource package, but your SFS file systems have used up the package capacity. In addition, your account balance is not enough to pay for the pay-per-use fees generated afterward.
• You have purchased an SFS Capacity-Oriented resource package and created a pay-per-use SFS Turbo file system. Your account balance is not enough to pay for the generated pay-per-use fees.
• You have created a yearly/monthly SFS Turbo file system and a pay-per-use SFS Capacity-Oriented file system. Your account balance is insufficient to pay for the generated pay-per-use fees.
• You have not purchased any SFS Capacity-Oriented resource package and your account balance is not enough after you create such a pay-per-use file system.
• You have created a pay-per-use SFS Turbo file system and your account balance is not enough to pay for the generated pay-per-use fees.

Service status and operation restrictions when an account is in arrears:

Your file systems are retained after your account is in arrears and file systems enter the retention period, but you cannot use the file systems. If the outstanding payment is not cleared before the retention period expires, data stored in the file systems will be deleted and cannot be recovered.

For details about the retention period, see Service Suspension and Resource Release.
