If an ECS or EVS disk is faulty or data is deleted accidentally, you can use data backups to quickly restore data. What Is CBR? CBR enables you to back up ECSs and EVS disks with ease.
Pay-per-Use Resources If pay-per-use resources, such as pay-per-use ECSs and EVS disks, are no longer required, delete them in a timely manner because the associated EVS disks and bandwidth are still billed even if the ECSs are already stopped.
IEC supports the deployment of cloud services such as ECS, EVS, SFS, OBS, and database services in HomeZones to ensure that your service data and configurations are stored locally. Your registration information is stored in the central AZ of the parent region.

Features Private Image Lifecycle After you create a private image, you can use it to create cloud servers or EVS disks. You can also share the image with other tenants or replicate it to other regions. Figure 1 shows the lifecycle of a private image.
Click Back to Disk List to return to the Elastic Volume Service page. Performance Modification If the disk performance no longer meets your service requirements, you can modify its IOPS by changing the disk type.
Use the API described in Deleting an EVS Disk (OpenStack Cinder API v2). Constraints If the volume has a snapshot not deleted, the volume cannot be deleted. A volume that is being attached to an ECS cannot be deleted. A volume that is being migrated cannot be deleted.
Cluster HA You can use a shared EVS disk to deploy an intra-AZ cluster or a mission-critical application with HA enabled. One shared EVS disk can be attached to up to 16 ECSs.
Data Backup and Restoration For persistent storage, you can use CCE to mount storage volumes created from EVS disks to a path of a container. CCE works with EVS to support snapshots. If data is lost, you can roll back the disk data to the state when a snapshot was created.
The possible causes and solutions are as follows: Issue description: Insufficient ECS, EVS disk or EIP quota. Possible cause: insufficient quota Handling method: Increase the quota or delete unnecessary resources, and then enable the AS group.

Billing Termination Yearly/Monthly Resources When you purchase a yearly/monthly resource, such as a yearly/monthly cloud phone server or EVS disk, you make a one-time up-front payment. By default, the billing automatically stops when the purchased subscription expires.

If other service products, such as EVS disks, EIPs, and bandwidths are bound to the BMS, these products are billed using their own billing mode (yearly/monthly or pay-per-use). Stopping a BMS will forcibly interrupt services running on it.
