Cygwin Windows < Linux rsync - 連接意外關閉

我正在嘗試將我的 Raspberry Pi 3 (Raspbian) 備份到我的台式電腦 (Windows 10 Pro)。目前我可以通過各種方式進行 SSH，指定私鑰文件。

從 Windows SSH 進入 RPi：ssh root@192.168.1.107 -i H:/ssh/BB8.OpenSSH.ppk（root 以確保我在測試期間沒有權限錯誤）。

從 RPi SSH 到 Windows：ssh matt@192.168.1.100 -i /home/pi/.ssh/RPi3.OpenSSH.ppk

以下 rsync 命令不起作用：（Windows > RPi）

rsync -vvvvna --exclude={"/proc/*","/sys/*","/dev/*","/boot/*","/tmp/*","/run/*","/mnt/*"} -e "ssh -i H:/ssh/BB8.OpenSSH.ppk" root@192.168.1.107:/* /cygdrive/h/Users/Matt/Documents/RPi3_Backup

Rsync 說“連接意外關閉”，而 RPi SSH 日誌說它“收到與 192.168.1.100 的斷開連接”。

同步輸出：

典型的——我一在這裡發帖就解決了問題（這個問題一直持續到晚餐和數小時的調試……）

可以作為可選 Windows 10 功能啟用的 OpenSSH 伺服器似乎無法與 Cygwin 的 rsync 配合使用。我通過 Cygwin 安裝了 OpenSSH，一切都按預期連接。

rsync -nva --exclude={"/proc/*","/sys/*","/dev/*","/boot/*","/tmp/*","/run/*","/mnt/*"} -e "C:/cygwin64/bin/ssh.exe -i /cygdrive/h/ssh/BB8.OpenSSH.ppk" root@192.168.1.107:/* /cygdrive/h/Users/Matt/Documents/RPi3_Backup
