    Hello Connie Gao Personal，

    如果你真的想備份整個 Windows 11（包含作業系統 + 安裝過的軟體 + 設定 + 個人資料），請按照下面步驟操作 — 單純做「建立 recovery USB / U-disk」不會做到這點。

    如何在 Windows 11 建立完整的系統映像備份（system image backup）

    1. 插入一個外接硬碟或大容量 USB 隨身碟（容量要足夠，最好是外接 HDD/SSD）。
    2. 開啟「控制台」（按 Win + R，輸入 control，按 Enter）。
    3. 進入「System and Security → Backup and Restore (Windows 7)」。
    4. 點左側「Create a system image」。
    5. 當系統提示「要把備份存到哪裡？」時，選擇你接的外接儲存裝置。
    6. 確認要備份的磁碟（通常是系統磁碟 C:），然後按「Start backup」。
    7. 等到備份完成 — 根據你系統資料量與外接硬碟／USB 的速度，可能需要一段時間。
    8. 完成後，在外接儲存設備上會看到一個名為 WindowsImageBackup 的資料夾 — 那就是你的完整系統映像備份。

    這樣備份下來的是 完整狀態：作業系統、系統檔案、已安裝的程式、系統設定、還有人資料。萬一系統當掉、硬碟壞掉，或者你換硬碟／重灌，也能把整個系統恢復到當時的樣子。

    如果你只是做「recovery drive → USB／U-disk」的話，那只是建立一個可以「開機修復或重新安裝 Windows」的媒體 — 不會包含你安裝過的程式、設定或個人檔案。除非你另行備份，否則重灌後這些都會不見。

    希望這有幫助。
