摘要

隨著時代的進步，個人所擁有的數位裝置已非僅侷限在個人電腦，而是充斥在各種智慧型行動裝置中。因此，各個裝置間檔案該同步的問題也隨之而來，而使用雲端儲存服務之檔案自動同步工具以進行同步已成為常見的方式。然而，雲端儲存服務的檔案自動同步工具是在有網際網路的條件下才能運作的，若無網際網路環境時，或者部分檔案具高度隱密性不宜使用雲端儲存服務時，即無法使用。黃大倫針對上述問題與單一使用者的檔案同步需求，提出了以Event History機制進行檔案同步的方法，並且實作了一套檔案自動同步工具「Syncher」。本論文以黃大倫所提出之同步方法與實作成果為基礎，提出一個在點對點架構下自動同步多個裝置的方法，以解決「Syncher」同時只能同步兩個裝置的問題，並改善整體的同步效率與穩定性，最後實做出一套能夠跨平台執行同步的點對點檔案自動同步工具。

Nowadays, in addition to personal computers, people have more and more portable digital devices. Therefore, synchronizing the files stored on all the devices has become an issue. It is common to use file-synchronization tools based on cloud storages. However, cloud-based synchronization services rely on the Internet to function properly. In case that the internet is not available or the files to be synchronized are highly confidential and are not suitable to be stored on the cloud storage, using such services is not appropriate. To resolve the problem, Ta-Lun Huang proposed a file-synchronization method based on a mechanism called Event History, and implemented a file-synchronization tool called Syncher. This thesis improves Syncher’s overall performance and stability, and resolves the problem that Syncher can only synchronize two devices at a time. Based on peer-to-peer architecture, the proposed method can be used to synchronize multiple devices simultaneously. In addition, an automatic file synchronization tool has been implemented.
