When you use Database Backup (DBS) to back up data, you are charged based on the volume and duration of your data stored in DBS.
After you configure and start a backup schedule, backup files are generated. Then, DBS charges you storage fees. If you configure a backup schedule to back up data to an Object Storage Service (OSS) bucket or a self-managed Network Attached Storage (NAS) file system, DBS does not charge you storage fees.
You can pay storage fees on a pay-as-you-go basis or purchase a subscription storage plan. This topic describes the billing methods and pricing for backup storage.
You do not need to specify the storage capacity when you purchase a backup schedule. The storage capacity is automatically increased when the amount of data increases. You are charged for the storage space that you use.
Storage fees = Storage volume (GB) × Unit price per month/30 days/24 hours.
The bill of the previous day is generated and fees are deducted at 00:00 every day.
|Region||Unit price for data storage (USD per GB per month)|

Subscription storage plan
If you want to store large volumes of data, we recommend that you purchase storage plans to reduce storage costs. A storage plan is more cost-effective than the pay-as-you-go billing method.
You can purchase storage plans of the following durations: one month, six months, and one year. If the space of storage plans is exhausted, you are charged for excess storage on a pay-as-you-go basis. For more information, see Use storage plans.

Storage plans are applicable to all regions around the world. When you use storage plans to deduct the storage volume for a backup schedule in different regions, different factors are used for deduction.
The storage volume that can be deducted from a storage plan is calculated based on the following formula: Storage volume generated * Deduction factor.
For example, you purchase a storage plan to deduct the storage volume for a backup schedule in the China (Hong Kong) region. If 50 GB of data is stored, 56.5 GB is deducted from the storage plan: 50 GB × 1.13 = 56.5 GB.
