The present invention relates to a cloud system and a method for compressing and sending a file in the cloud system, wherein when a user who accesses a cloud computing system and uploads or downloads files requests a target compression file to be compressed, whether the same file as the target compression file is stored in the cloud system or not is check and if, as a result of the check, the same file is present, an ID code of the target compression file is stored while compressing the target compression file. In accordance with the present invention, there are advantages in that a load of the cloud system can be reduced and there is a marginal network band because the same file is not redundantly stored if the same file is present in the cloud system.
