臺灣博碩士論文加值系統

隨著電腦與網路科技的進步，資料備份在學校變成一門必修的課程，尤其在病毒肆虐的網路環境中，電腦教室系統的備份更顯得重要。Ghost與Partimage是專門應用於部署作業系統之工具，它提供本端(Local)系統備份與還原的功能，但是面對擁有多電腦環境下(例如教育單位、電腦教室等)，必須個別對每台系統部署頗為曠日費時，因此一對多的網路備份軟體可提供一個有效的解決方案。本論文在於Embedded架構下以自由軟體(Free Software) Partimage為基礎提出群播(Multicast)應用，Embedded架構擁有價格低與耗電量低的優勢，並且整體構造相對較精簡，適合應用於輕量級伺服器，而自由軟體賦予軟體使用者擁有使用、修改之特性。在實驗成果中以Partimage做開發基礎，使其具有群播(Multicast)可以透過網路實現大量部署作業系統。伺服器端將會整合網路開機(LAN boot)及撰寫Partimage Web操作介面，而Client端允許透過Web操作將系統備份到遠端資料庫伺服器，而資料庫伺服器將設計Embedded架構上並採用新的大量部署方式，以Partimage為基礎與Udp-cast做整合，透過Udp-cast改變原來Partimage的一對一傳輸模式來達成一對多Multicast系統部署。

Ghost and Partimage are tools utilized for deploying the operation system; they offer local system with the function of backup and restore. Under the circumstances of operating many computers at the same time (in educational departments or computer classrooms), it is time-consumed to deploy the system of each computer. Thus one-to-many online backup software provides an effective solving project for this problem.
Our study offers Multicast application with base of (Free Software) Partimage software under the embedded structure; Partimage is used as develop foundation to implement Multicast and mass deploying operation system through internet. Server can concord internet start-up (LAN boot) and compose operation interface of Partimage Web; client can permit transferring system backup to distant server through Web operation. Database server utilizes new method of mass deploying and embedded structure in addition to the concord of Udp-cast and Partimage in order to change the one-to-one mode of transmission into one-to-many Multicast deploying system.
