Storage package billing
Overview
Baidu AI Cloud File System (CFS) offers users two flexible billing methods: pay-as-you-go and storage package billing.
The storage package service is based on a pre-payment model. By purchasing a storage package, you can reserve cloud storage resources upfront, enjoy discounted rates, and effectively lower resource costs.
Currently, two binding options are available: First, create a file system and then bind the purchased storage package to it. Alternatively, create a new file system while purchasing the storage package and bind them simultaneously. After purchasing a storage package, any usage costs for the associated file system will be primarily offset by the storage package. Usage that exceeds the package's capacity will be billed on a pay-as-you-go basis.
Purchasing a storage package
Sign in directly to the Cloud File System (CFS) Console, and click the Storage Packages tab in the left navigation bar to purchase a package. During purchase, follow the prompts to select the storage package type, region, associated file system, specification, purchase duration, effective date, and auto-renewal status. Detailed purchase interface and parameters:
| Parameters | Description |
|---|---|
| Storage package type | Storage package type. It includes performance-optimized and capacity-optimized types. Different package types apply to corresponding file system types.A performance-optimized/capacity-optimized storage package can only be bound to a performance-optimized/capacity-optimized file system. |
| Region selection | Select the region to which the storage package belongs.A storage package can only be bound to file systems in the same region. |
| Associated file system | A storage package must be bound to a single file system (one package per file system). You can either bind it to an existing file system or create a new one. Ensure that the storage package type matches the type of the file system. |
| Specification | Choose the storage package specification that meets your requirements. Any usage beyond the package's capacity will incur pay-as-you-go charges. |
| Purchase period | Select the duration of the storage package based on your requirements. Once the package expires, the file system will transition to pay-as-you-go billing. |
| Effective date | Choose the storage package's effective date according to your needs. Immediate activation and activation at a specified time (to the minute) are both supported. |
| Auto-renewal | Determine whether to enable auto-renewal. If enabled, the system will automatically renew the storage package with the same specifications and validity period once it expires. |

Storage package statuses
Common storage package statuses:
| Storage package statuses | Status description |
|---|---|
| Creating | The purchased storage package is being created |
| Active | The storage package is in effect and can offset the storage costs of the bound file system |
| Pending activation | The storage package is pending activation; it will start offsetting costs after the specified effective time |
| Invalid | The storage package is automatically invalidated when the bound file system is deleted, and cannot be bound to a new file system |
| Expired | When the storage package expires, you can purchase a new one with the same configuration. |
| Cancelled | The purchased storage package is cancelled if a refund is processed, or 7 days after the package expires |
Billing rules
- Storage packages are prepaid and require a one-time payment at the time of purchase.
- Validity period: You can opt for immediate activation or activation at a specified time (to the minute) when making your purchase.
-
While the storage package is active, the costs for the associated file system will first be offset by the package. Any usage that exceeds the package's capacity will incur pay-as-you-go charges. Example:
- You have two active 100 GB storage packages bound to file system A. If file system A uses 180 GB (180 GB < 200 GB), the usage is within the total package capacity, so costs are fully offset by the packages;
- If you have two active 100 GB storage packages bound to file system A and file system A uses 250 GB (250 GB > 200 GB), the additional 50 GB will be billed on a pay-as-you-go basis.
- If a storage package is activated halfway through an hour, the cost will be proportionally deducted in the next hourly bill, rather than being fully deducted.
- You can buy multiple storage packages, and they can all be active at the same time.
- Refund Policy: A full refund is available if the storage package hasn’t been used (i.e., not yet activated) and the refund request is submitted within 7 days of purchase. Refunds are not available once the package has been used or if the 7-day period has passed.
- Expiration Notice: Expired storage packages become invalid immediately. You will receive reminder notifications 7 days before expiration and on the expiration date itself.
