**Table 1** Fault recovery
Method	Description	Reference
EVS backup	CBR provides the cloud disk backup function, which allows you to back up EVS disks while the servers are running. In case of a virus, accidental deletion, or software/hardware fault, you can restore data to any point in the past when backups were created to guarantee data integrity and security.

Disk creation from snapshots	You can use EVS snapshots to create new disks so that the new disks will contain the snapshot data once being created.	Creating an EVS Disk from a Snapshot (OBT)
Snapshot data rollback to disks	If data on an EVS disk is incorrect or damaged, you can quickly restore data by rolling back the disk to the state when the snapshot was created.	Rolling Back Data from a Snapshot (OBT)
