    Abstract: 因為傳輸網路不斷演進速度和費用不斷提升和降價,使用網路的人數因此不斷的擴大,而使用的族群也越來越大眾化,依據國際市調機構Gartner在2014年3月發佈的統計資料所述2014年約24.79億台裝置出貨,其中有76%以上為用來與網路進行資料存取的行動設備,其中包含筆記型電腦、智慧型手機、平版電腦等,網路的普及和便利性已漸漸地影響資料的產生方式。依據2014年EMC數位世界研究報告所述2013年全球資料量約4.4 ZettaByte到2020年將成長到44 ZettaByte,在2013年有2/3約2.9ZByte資料量是由個人產生,且其中85%約2.3ZByte為個人或工作者使用企業所提供的服務例如Email等所產生,因此如何提供移動裝置快速的資料上傳和備份資料為面對資料高速成長時代必須面對的問題。

    本論文介紹了一種用於行動裝置跨國或跨區域的動態資料備份和上傳的機制,主要為解決電腦設備在進行跨國或跨區檔案傳送時因遠距傳輸高延遲(high latency)所產生的檔案上傳效率不佳的問題,提出一種動態方式選擇最近的資料上傳儲存結點來進行資料快速上傳作業,並透過結點之間的同步機制來建立全球性的檔案儲存架構。;Owing to the evolving transmission network providing faster transmission speed and lower user cost, the number of internet users in the population continues to increase. According to international market research firm Gartner, Inc. (March 2014), worldwide combined shipments of devices (PCs, Tablets, Ultramobiles and Mobile Phones) are projected to reach 2.479 billion units in 2014, of which 76% is mobile devices used for internet data access (including laptops, smart phones, tablets, etc.). The popularity and convenience of Internet has gradually impact the way data is generated. Based on 2014 EMC Digital Universe research report by IDC, there were approximately 4.4 Zettabytes of information in the digital universe in 2013 and this number is expected to reach 44 Zettabytes by 2020. In 2013, 2/3 of information (about 2.9ZByte) is generated by individuals, of which 85% (approximately 2.3ZByte) is from services provided for individuals or workers like emails, so how to provide mobile devices fast data upload and backup is a key problem confronting the high growth era of the information.

    This research describes the profile of a multinational or interregional mechanism for dynamic data backup and upload for mobile devices, mainly aimed at solving upload inefficiency caused by high latency of long-distance transmission when conducting cross-border or cross-region file transfer, and proposing a dynamic method to select the most nearby storage nodes for quick upload and through a synchronization mechanism between nodes to create a global file storage architecture.
