阿里云国际(AlibabaCloud)之前的快照一直都是免费供大家使用, 但就在刚刚收到他们的邮件.
说快照马上马上要正式商用, 也就是要收费了, 不需要的朋友请赶快删除自动快照策略.

Dear Customers,

We believe that the snapshot has been a vital method to back up and recover your service data during the open beta program. Therefore, Alibaba Cloud snapshot will be commercially available across all regions and provide professional data recovery and restoration service as of July 18, 2019. For more information about the offered price list, please visit the page.

If you no longer need to use snapshots, delete your snapshots in all regions and disable the Automatic Snapshot feature before July 18, 2019, so as to avoid unnecessary costs. Otherwise, you will be billed on a per-hour basis based on the Pay-As-You-Go method of your existing snapshots thereafter.

Thanks for your support!
Alibaba Cloud

遗憾的是阿里云国际收费标准我也没有找到, 不知道是不是按照OSS的存储标准计算.
