這是 Comodo 公司又一力作，除了它的強悍的免費版防火牆軟體 + 防毒軟體 Comodo Internet Security 之外，它的這個免費版的備份軟體同樣也非常棒，除了支援一般的資料夾檔案備份外，也支援系統磁區的備份(就是一般 windows 的 C 槽)、以及 MBR (Master Boot Record 主啟動開機磁區)、還有登錄檔的備份、使用者設定檔的備份、email (Outlook Express、Mozilla Thunderbird、Windows Live Mail)、Windows Live Messenger、Skype 等等的備份，支援本地、網路硬碟及 ftp 備份方式，支援排程、還原及 Windows Server 2008 備份，它的備份檔副檔名為 .cbu，目前還沒支援繁體中文介面，總之這是個免費又好用的工具，試看看。
