The present invention is applied to the field of computer network communications, and provided are a method and device for achieving data roaming. The method comprises: a client obtaining a data roaming voucher uniquely corresponding to user logon information; the client sending a data roaming request with the data roaming voucher to a data roaming server; and according to the data roaming voucher contained in the received data roaming request, the data roaming server verifying whether the data roaming request is valid, and transmitting roaming data between the client and the data roaming server if the data roaming request is valid. Before data communication is conducted between a client and a data roaming server, the step of verifying the validity of a user data roaming request is also required, and thus, the present invention can achieve the secure isolation of user information. In addition, the data roaming server uses a user network system structure in a catalogue form, thereby ensuring the file locating expandability and universality. |

1. A method for data roaming, comprising:
obtaining, by a client, a data roaming ticket uniquely corresponding to user login information; sending, by the client, a data roaming request comprising the data roaming ticket to a data roaming server; verifying, by the data roaming server, whether the data roaming request is valid based on the data roaming ticket comprised in the received data roaming request; performing roaming data transmission between the client and the data roaming server if the data roaming request is valid, wherein performing the roaming data transmission between the client and the data roaming server comprises: uploading user data to the data roaming server by the client and synchronizing stored corresponding user data with the client by the data roaming server; allocating, by the data roaming server, a user network file system to store user data for a corresponding user, wherein the user data in the user network file system exists in a form of catalogue, and corresponding catalogue and user data are identified and located through a relative path; and establishing, in the user network file system, a virtual file index corresponding to a catalogue structure of the user network file system and a local file index adapted to load data saved locally and recently, wherein a local file operation is performed by comparing the two indexes and invoking a file operation interface function. |
