Abstract
Disclosed are a data synchronization method, system, data synchronization server and terminal. A synchronization server determines the source of corresponding digital content according to the brief information uploaded by a user, and determines, according to the source of the digital content, to store the brief information only or further store the storage position information of the digital content or the digital content itself, thus reducing the data traffic for data backup, simplifying data migration difficulty when the user replaces a terminal, and reducing the communication cost of the user and the network resource pressure of a carrier.
Claims19
A data synchronization method, comprising:
- receiving first summary information uploaded by a first terminal, wherein the first summary information comprises metadata of digital contents, and personalized configuration information of a user, and the metadata of the digital contents comprises a source of the digital contents;
- and
- determining whether the digital contents are achieved from a content server, according to the source of the digital contents, and
- if the digital contents are achieved from the content server, storing the first summary information.
A data synchronization server, comprising:
- a receiving module configured to receive first summary information uploaded by a first terminal, wherein the first summary information comprises metadata of digital contents, and personalized configuration information of a user, and the metadata of the digital contents comprises a source of the digital contents;
- a first determining module configured to determine whether the digital contents are achieved from a content server, according to the source of the digital contents;
- and
- a storing module configured to store the first summary information if the digital contents are achieved from the content server.
A data synchronization system, comprising a first terminal and a data synchronization server, wherein:
- the first terminal is configured to upload first summary information to the data synchronization server, wherein the first summary information comprises metadata of digital contents, and personalized configuration information of a user, and the metadata of the digital contents comprises a source of the digital contents;
- and
- the data synchronization server is configured to determine whether the digital contents are achieved from a content server, according to the source of the digital contents, and to store the first summary information if the digital contents are achieved from the content server.
A terminal, comprising:
- a storing module configured to store summary information, wherein the summary information comprises metadata of digital contents, and personalized configuration information of a user, and the metadata of the digital contents comprises a source of the digital contents;
- and
- an uploading module configured to upload the summary information and to upload the corresponding digital contents, according to a digital content uploading request message transmitted by a data synchronization server.
