Suggestions on Selecting a Backup Type
CBR supports backup of multiple resources. You can compare the backup types to determine which one is suitable for your data.
Backup Objects and Scenarios
You can select a backup type based on the backup objects, service scenarios, and advantages described in the following table.
Item |
Cloud Server Backup |
Cloud Disk Backup |
SFS Turbo Backup |
Cloud Desktop Backup |
---|---|---|---|---|
What to back up |
All disks (the system disk and data disks) on a server or certain disks and cloud servers running applications such as databases |
One or more specific disks (the system disk or data disks) |
SFS Turbo file systems |
Entire Workspace desktop systems, including all disks |
When to use |
You want to back up entire cloud servers. |
You want to back up only data disks, as the system disk contains no user data. |
You want to back up only SFS Turbo file systems. |
You want to back up only Workspace desktops. |
Advantages |
All disks on a server are backed up at the same time to ensure data consistency. |
Only data of specific disks is backed up, which costs less than backing up an entire server. |
File system data and their backups are stored separately, and the backups can be used to restore file systems. |
Desktop data and their backups are stored separately, and the backups can be used to restore desktops. |
Cloud server backup includes non-database server backup and database server backup. If you need to back up cloud servers, you can select a backup type based on the database deployment and service requirements.

Recommended scenario |
Data of cloud servers and their databases such as MySQL or SAP HANA database needs to be backed up. All data and application configurations need to be restored in case of an error. |
Only data of cloud servers needs to be backed up. Such data needs to be restored in case of an error. If you use cloud server backup to back up database servers such as MySQL or SAP HANA database servers, certain database configurations may not be fully restored from the backups. This can result in startup issues when the database is restarted. |
Backup Policy Settings
You are advised to configure different data backup policies based on service system levels. The following table shows the commonly used backup policies for cloud resources. You can adjust the policies based on service requirements. For details, see Creating a Backup Policy.
