| Remarks | At any time, the client may choose to abort the BACKUP or RESTORE operation. This routine signals that all operations should cease. The state of the overall virtual device set enters the Abort state. No further commands are returned on any devices. All uncompleted commands are automatically completed, returning ERROR_OPERATION_ABORTED as a completion code. The client should call IClientVirtualDeviceSet2::Close after it has safely terminated any outstanding use of buffers provided to the client. For more information, see Abnormal Termination. | |
