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).

Claims

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).

2. A data storage method according to claim 1, characterized in that in order to manage inter-user deduplication, the intermediate device performs the following steps:

a) a step of creating an identifier (IDsys) associated with data (DE) for saving as received from a first device; and

b) a transmission step during which the intermediate device transmits at least the identifier (IDsys) to the second device for managing inter-user deduplication of the data (DE).

3. A storage method according to claim 1, characterized in that in order to manage intra-user deduplication:

a) the first device creates a first identifier (IDD) associated with data (D) for saving; and

b) the first device transmits the identifier (IDD) to the intermediate device (I) for managing intra-user deduplication.

4. A storage method according to claim 2, characterized in that the intermediate device stores correspondence between the identifiers associated with intra-user deduplication and the identifiers associated with inter-user deduplication.

5. A storage method according to claim 1, characterized in that the intermediate device (I) is situated on a communications link through which the first device communications with the second device.

6. A storage method according to claim 5, characterized in that the intermediate device (POP) is a device on the link that is suitable for aggregating data streams from first devices.

7. A storage method according to claim 1, characterized in that, at the end of inter-user deduplication, the intermediate device (I) transmits information about the saving performed, and in that the instant at which the information is transmitted is delayed.

11. A storage method according to claim 3, characterized in that the intermediate device stores correspondence between the identifiers associated with intra-user deduplication and the identifiers associated with inter-user deduplication.

8. A computer program including code instructions for performing a method when the program is executed by a processor, the 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).

9. A device (I) comprising a communications module for communicating with a plurality of first devices (PC1) having respective storage modules for storing data belonging to respective users (U1), and with a second device (SS) suitable for managing saving of data coming from first devices, said saving including a step of inter-user data deduplication, the device being characterized in that it comprises:

a) a first module for managing intra-user deduplication on data for saving coming from first devices; and

b) a second module for managing inter-user deduplication in co-operation with the second device (SS).

10. A computer system (SYS) comprising a plurality of first devices (PC1) having respective storage modules for storing data belonging to respective users (U1), and a second device (SS) suitable for managing saving of data from first devices, said saving including a step of inter-user data deduplication, the system being characterized in that an intermediate device is interposed between the first devices and the second device, the intermediate device (I) comprising:

a) a first module for managing intra-user deduplication on data for saving coming from first devices; and

b) a second module for managing inter-user deduplication in co-operation with the second device (SS).
