          Cloud File Storage

          On-Demand Billing

          Baidu AI Cloud File Storage (CFS) provides users with two flexible purchase methods, on-demand billing or annual and monthly prepaid (that is, storage package) billing. The on-demand billing service adopts the post-paid method, which automatically expands or reduces capacity according to your actual usage, and is billed in real time by the minute; in addition, the unit price is different for different storage types of file systems. The specific rules are as follows:

          • Billing item

            CFS provides a "Storage Space" billing item, which is based on the amount of space occupied by users to store data:

            Storage type Billing item Unit price (RMB/GB/month)
            Performance type CFS Storage space 1.8
            Capacity type CFS Storage space 0.35

          Note:

          • The month in the "RMB/GB/month" in the billing item refers to 30 days. For example, the unit price of RMB 1.8/GB/month refers to the cost of RMB 1.8 for the storage of 1GB data in 30 days;
          • The generated directory is not included into the storage space;
          • The storage space per file is aligned in units of 4KB. For example, if the length of a file is 3KB, it is calculated as 4KB;
          • File holes are not counted as storage space. File holes are bytes that are not actually written to the file.
          • Bill by minute, and less than one minute is counted as one minute.
          • Peak hour deduction, that is, deduct hourly Beijing time and generate a bill, and the peak storage amount in the last hour is charged. Billing time is within 1 hour after the end of the current billing cycle. For example, a bill from 10: 00 to 11: 00 will be generated before 12:00, depending on the system's billing time.
          • Cost per hour = Maximum storage capacity per hour (peak value)* Unit price per hour
