Snapshot service upgrade and addition of a new billable item on December 30, 2020
The Alibaba Cloud snapshot service will be upgraded on December 30, 2020.During this upgrade, the local snapshot feature will be upgraded to the instant access feature. Furthermore, the number of requests made to enable the instant access feature is added as a billable item. The new feature and billable item take effect on December 30, 2020. We apologize for any inconvenience caused by these changes. Submit a ticket or call 95187 if you encounter any problems.
After the snapshot service is upgraded, the local snapshot feature is upgraded to the instant access feature, and local snapshots are no longer provided as a separate category of snapshots. You can choose whether to enable instant access when you create snapshots for enhanced SSDs (ESSDs). Normal napshots with instant access enabled have the same capabilities as local snapshots.
The number of requests made to enable instant access is added as a billable item. After the upgrade, you are charged for the use of instant access based on the number of times that you enable this feature. For example, if you enable instant access when you create a snapshot, you are charged for this one request. You are not charged for disabling instant access.
