Impacts and Usage Suggestions on Yearly/Monthly Disks Before and After Expiration

Introduction to Retention Period of Yearly/Monthly Resources

Yearly/Monthly is a prepaid billing mode, of which resource charges are paid in advance. You can choose yearly/monthly billing when purchasing disks.

Before a yearly/monthly disk expires, if you do not renew the disk or auto renewal is enabled but fails, the disk will enter the retention period after expiration.

During the retention period, if you renew the disk, the disk will be unfrozen.
During the retention period, if you do not renew the disk, the disk will be released after the retention period ends.

The duration of the retention period varies depending on user levels. For more information, see Resource Suspension and Release.

Figure 1 Impacts on yearly/monthly resources before and after expiration

Impact on Services When Resources Are Frozen, Unfrozen, or Released

Frozen resources: Resource access and usage are restricted, which will interrupt your services. For example, if a server is frozen, it will be automatically powered off or shut down. If a disk is frozen, disk I/Os will be restricted.
Unfrozen resources: Resource restrictions are removed, but you need to check and restore your services. For example, after a server is unfrozen, you need to power it on.
Released resources: Resources are released. Data stored on the resources will be deleted and cannot be retrieved.

Usage Suggestions on Yearly/Monthly Resources

If you no longer need to use a yearly/monthly disk after it expires, you can log in to the management console, detach the disk, and release the resource. For details, see section "Releasing Resources" in the Billing Center User Guide.

Table 1 lists the common usage scenarios and suggestions on yearly/monthly disks. You can refer to usage suggestions to enable auto renewal and set a renewal date, and pay attention to resource expiration and freezing notifications to keep up with the latest resource information, ensuring that your services and data are not affected.
