A storage plan is a subscription-based resource plan for PolarDB. You can use storage plans to offset storage fees, fees for level-1 backups that exceed the free quota, fees for level-2 backups, fees for log backups, and OSS storage fees for archived cold data. Storage plans can help you save costs. If you select a larger capacity and a longer duration for the storage plan you purchase, you can receive a higher discount. For example, a monthly storage plan provides 10% to 45% savings when compared with a comparable pay-as-you-go cluster. The longer the duration of the plan, the more savings you get. If you purchase annual storage plans, you can save an additional 15% off the monthly price. This topic describes how to purchase a storage plan.

Precautions
- Storage plans can be used by all PolarDB for MySQL clusters in the regions that are specified by the Plan Type parameter. You can select Chinese Mainland or Outside Chinese Mainland.
- If the capacity of your storage plan is insufficient, you can purchase an additional storage plan or upgrade the storage plan. However, storage plans cannot be downgraded.
- If the amount of used storage exceeds the capacity of your storage plan, you are charged for the additional storage resources based on the pay-as-you-go billing method.
For example, assume that you have created three PolarDB for MySQL clusters that each requires 400 GB of storage. If you purchase a storage plan of 1,000 GB and these clusters share the storage plan, the storage resources used in excess of 200 GB are billed on a pay-as-you-go basis. For more information, see View the database storage usage.
