  Parameter	Type	Mandatory	Description
  volume_id	String	Yes	Specifies the ID of the snapshot's source disk.
  force	Boolean	No	Specifies the flag for forcibly creating a snapshot. The default value is false. If this parameter is set to false and the disk is in the attaching state, the snapshot cannot be forcibly created. If this parameter is set to true and the disk is in the attaching state, the snapshot can be forcibly created.

  description	String	No	Specifies the snapshot description. The value can be null. The value can contain a maximum of 255 bytes.
  name	String	No	Specifies the snapshot name. The value can contain a maximum of 255 bytes. NOTE: When creating a backup for a disk, a snapshot will be created and named with prefix autobk_snapshot_. The EVS console has imposed operation restrictions on snapshots with prefix autobk_snapshot_. Therefore, you are advised not to use autobk_snapshot_ as the name prefix for the snapshots you created. Otherwise, the snapshots cannot be used normally.
