CBR backs up data of EVS disks and uses the backup to create new disks. EVS Creating a Cloud Disk Backup Cloud Trace Service (CTS) records operations on CBR resources, facilitating future queries, audits, and backtracking.
Fault Recovery CBR allows you to back up and restore cloud resources, including ECSs, EVS disks, SFS Turbo file systems, and Workspace desktops. If a resource fails, you can use backups to quickly restore data and services. For more information, see Function Overview.
If you back up multiple EVS disks separately, the backup time points of the EVS disks are different. As a result, the backup data of the EVS disks is inconsistent.
Cloud Backup and Recovery (CBR) allows you to easily back up Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), and Elastic Volume Service (EVS) disks.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Quotas can limit the number or amount of resources available to users, such as the maximum number of ECS or EVS disks that can be created. If the existing resource quota cannot meet your service requirements, you can apply for a higher quota. How Do I View My Quotas?
Troubleshooting Methods When attaching an EVS disk, use parameters without UUID control or reallocate a new UUID to ensure that each UUID is unique. Solution Log in to the server to which EVS disks failed to be attached.

Disk backups can only be used to create EVS disks, not servers. Billing You need to pay for the EVS disk when creating it from an EVS disk backup. For details about billed items, see Billing for EVS Disks. For details about pricing, see Elastic Volume Service Pricing.
Use a backup to create an EVS disk, associate the EVS disk with a server, and export data to that server. Attach the new disks to the new server. For details, see Attaching a Non-Shared Disk or Attaching a Shared Disk. Parent topic: Others
You can also use a system disk backup to create an EVS disk. Disks created using system disk backups can only be used as data disks on servers. They cannot be used as system disks. Parent topic: Restoration
For details, see section "Disk Capacity Expansion" in the Elastic Volume Service User Guide. Parent topic: Restoration
Overview Cloud Backup and Recovery (CBR) enables you to easily back up Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), Elastic Volume Service (EVS) disks, SFS Turbo file systems, local files and directories, and on-premises VMware virtual environments.
Figure 1 Locating the target backup The EVS disk data will be overwritten by the data captured at the time of backup. The restoration cannot be undone. If the restore button is grayed out, stop the server, detach the disk, and then try again.
For details, see Obtaining an EVS Disk ID. resource_id No String ID of the resource to be restored. It is in UUID format.
Use a backup to create an EVS disk and associate the EVS disk with a server. For details, see Attaching a Non-Shared Disk or Attaching a Shared Disk. Then copy data in the data disk to the system disk. Parent topic: Restoration
