What Are the Differences Between Cloud Server Backup and 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.
