Abstract

A network storage deduplicating method and a server using the same method are proposed. The method includes the following steps: receiving a first data through an Internet small computer system interface protocol; calculating identification information of the first data; determining whether a second data having the identification information is already stored in the server; if yes, generating and storing a pointer pointing to the second data and neglecting the first data.

Claims

1. A network storage deduplicating method, adapted for a server, comprising:

receiving a first data through an Internet small computer system interface protocol;

calculating identification information of the first data;

determining whether a second data having the identification information is already stored in the server; and

if the second data having the identification is already stored in the server, generating and storing a pointer pointing to the second data and neglecting the first data.

2. The method as claimed in claim 1, wherein the first data is a part of data of a transmitted file.

3. The method as claimed in claim 2, wherein the step of calculating the identification information of the first data comprises:

when a data size of the first data meets a predetermined data size, calculating the identification information of the first data.

4. The method as claimed in claim 1, wherein when second data is not stored in the server, the method further comprises:

storing the first data and recording the identification information of the first data.

5. The method as claimed in claim 4, wherein the step of calculating the identification information of the first data comprises:

calculating a hash value of the first data as the identification information of the first data.

6. A server, comprising:

a storage unit, storing a plurality of modules;

a communication unit;

a processing unit, coupled to the storage unit and the communication unit and accessing and executing the modules, wherein the modules comprise;

a receiving module, controlling the communication unit to receive a first data through an Internet small computer system interface protocol;

a calculating module, calculating identification information of the first data;

a determining module, determining whether a second data having the identification information is already stored in the server; and

a generating module, generating and storing a pointer pointing to the second data and neglecting the first data when the server already stores the second data having the identification information.

7. The server as claimed in claim 6, wherein the first data is a part of data of a transmitted file.

8. The server as claimed in claim 7, wherein when a data size of the first data meets a predetermined data size, the calculating module calculates the identification information of the first data.

9. The server as claimed in claim 6, wherein the modules further comprise a recording module for storing the first data and recording the identification information of the first data when the second data is not stored in the server.

10. The server as claimed in claim 9, wherein the calculating module calculates a hash value of the first data as the identification information of the first data.
