CBR

What Is CBR?

Cloud Backup and Recovery (CBR) enables you to back up cloud servers and disks with ease. In case of a virus attack, accidental deletion, or software or hardware fault, you can restore data to any point in the past when the data was backed up.

CBR protects your services by ensuring the security and consistency of your data.

Differences Between Cloud Server Backup and Cloud Disk Backup

You can back up ECS data using Cloud Server Backup or Cloud Disk Backup.
  • Cloud Server Backup (recommended): Use this backup function if you want to back up the data of all EVS disks (system and data disks) on an ECS. This prevents data inconsistency caused by time difference in creating a backup.
  • Cloud Disk Backup: Use this backup function if you want to back up the data of one or more EVS disks (system or data disk) on an ECS. This minimizes backup costs on the basis of data security.

Item

Cloud Server Backup

Cloud Disk Backup

Resources to be backed up or restored

All disks (system and data disks) on a server

One or more specified disks (system or data disks)

Recommended scenario

An entire cloud server needs to be protected.

Only data disks need to be backed up, because the system disk does not contain users' application data.

Advantages

All disks on a server are backed up at the same time, ensuring data consistency.

Backup cost is reduced without compromising data security.
