You can use a disk backup to create a disk. After the disk is created, data on the new disk is the same as that in the disk backup.
After a new disk is created using the backup data of a system disk, the new disk can only be mounted to the cloud server as a data disk and cannot be mounted as a system disk.
For details about these parameters, see the parameter description table in section "Create an EVS Disk" of the Elastic Volume Service User Guide.
Note the following items when setting disk parameters:
If the capacity of the new disk is greater than that of the backup source disk, initialize the disk by following the steps provided in section "Extending Disk Partitions and File Systems" of the Elastic Volume Service User Guide.
You will see the disk status change as follows: Creating, Available, Restoring, Available. You may not notice the Restoring status because Instant Restore is supported and the restoration speed is very fast. After the disk status has changed from Creating to Available, the disk is successfully created. After the status has changed from Restoring to Available, backup data has been successfully restored to the created disk.
