METHOD FOR STORING DATA IN A COMPUTER SYSTEM PERFORMING DATA DEDUPLICATION
First Claim
1. A method of storing data in a computer system (SYS) comprising a plurality of first devices (PC1, PC2) storing data belonging to respective users (U1, U2), and a second device (SS) suitable for managing the saving of data coming from first devices, said saving including a step of inter-user data deduplication, the method being characterized in that an intermediate device (I) is interposed between the first devices (PC1, PC2) and the second device (SS) so as to perform intra-user deduplication on the data for saving coming from first devices, and then to manage inter-user deduplication in co-operation with the second device (SS).

Abstract
The invention relates to a method of storing data in a computer system (SYS) comprising a plurality of first devices (PC1, PC2) storing data belonging to respective users (U1, U2), and a second device (SS) suitable for managing the saving of data coming from first devices, said saving including a step of inter-user data deduplication, the method being characterized in that an intermediate device (I) is interposed between the first devices (PC1, PC2) and the second device (SS) so as to perform initially intra-user deduplication on the data for saving coming from first devices, and then to manage inter-user deduplication in co-operation with the second device (SS).
