计费方式
云数据库 SQL Server 提供如下一种计费模式：
计费模式 | 付费模式 | 适用场景 |
按量计费 | 后付费模式，即先按需申请资源使用，在结算时会按您的实际资源使用量收取费用。 | 适合业务量有瞬间大幅波动的业务场景，用完可立即释放实例，节省成本。 |
实例价格
计费公式
总费用 = 实例规格费用 + 存储空间费用 + 备份空间费用
计费项
计费项 | 说明 |
实例规格费用 | 在购买页选择的实例规格的费用，支持按量计费。 只读实例规格价格。 |
存储空间费用 | 在购买页选择的硬盘大小的费用，支持按量计费。 只读实例存储价格。 |
备份空间费用 | 用于存储某个地域下所有云数据库 SQL Server 实例的备份文件，备份文件由自动数据备份、手动数据备份以及日志备份组成。 |
说明：
云数据库 SQL Server 会按地域赠送一定额度的免费备份空间（跨地域备份不存在免费空间，实例只要开启了跨地域备份功能，所产生的全部备份文件均会收费），免费备份空间大小为您在对应地域下所有单节点（原基础版）和双节点（原高可用版/集群版）实例的主实例的存储空间之和，超过赠送空间的备份于2022年07月10日0时起，正式开始收费。
