Zusammenfassung:	The invention discloses a storage gateway based data duplication eliminating method, system and device. The method comprises the steps of, by a storage gateway, calculating an abstract of a to-be-loaded file and sending the abstract to a server so as to enable the server to send out a permission validation challenge instruction or a file loading instruction; by the storage gateway, generating a response array based on the permission validation challenge instruction of the server to enable the server to perform permissions validation; by the storage gateway, loading the to-be-loaded file to theserver by combining with a confused file based on the file loading instruction of the server; by the server, receiving the abstract of the to-be-loaded file which is sent by the storage gateway; andby the server, performing repeated checking on the abstract of the to-be-loaded file to generate the file loading instruction or the permission validation challenge instruction. The system comprises the storage gateway and the
