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.

**Table 1** Differences among the backup types
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.

**Table 2** Differences between database server backup and cloud server backup
Item	Database Server Backup	Cloud Server Backup
Object	Cloud servers with MySQL or SAP HANA database deployed	Cloud servers without databases
Granularity	Cloud server	Cloud server
Vault	Server backup vault	Server backup vault
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.

System Level	Backup Object	RPO	Retained Duration	Full Backup	Incremental Backup	Remote Backup	Drill Frequency
Core system	Cloud server	4 hours	> 1 year	Weekly	6 times/day	Yes	Monthly
	Cloud database	4 hours	> 1 year	Weekly	6 times/day	Yes	Monthly
	SFS Turbo file system	4 hours	> 1 year	Weekly	6 times/day	Yes	Monthly
Important system	Cloud server	12 hours	1 year	Every two weeks	2 times/day	Yes	Quarterly
	Cloud database	12 hours	1 year	Every two weeks	2 times/day	Yes	Quarterly
	SFS Turbo file system	12 hours	1 year	Every two weeks	2 times/day	Yes	Quarterly
General system	Cloud server	24 hours	6 months	Monthly	1 time/day	No	Half a year
	Cloud database	24 hours	6 months	Monthly	1 time/day	No	Half a year
	SFS Turbo file system	24 hours	6 months	Monthly	1 time/day	No	Half a year
