我正在尝试将我的 Raspberry Pi 3 (Raspbian) 备份到我的台式计算机 (Windows 10 Pro)。目前，我可以通过指定私钥文件的方式进行 SSH 连接。
从 Windows 通过 SSH 进入 RPi：（root 以确保在测试期间没有权限错误）。ssh [email protected] -i H:/ssh/BB8.OpenSSH.ppk
要从 RPi 通过 SSH 进入 Windows：ssh [email protected] -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" [email protected]:/* /cygdrive/h/Users/Matt/Documents/RPi3_Backup
Rsync 说“连接意外关闭”，而 RPi SSH 日志说它“从 192.168.1.100 断开连接”。
Rsync 输出：
cmd=ssh -i H:/ssh/BB8.OpenSSH.ppk machine=192.168.1.107 user=root path=/*
cmd[0]=ssh cmd[1]=-i cmd[2]=H:/ssh/BB8.OpenSSH.ppk cmd[3]=-l cmd[4]=root cmd[5]=192.168.1.107 cmd[6]=rsync cmd[7]=--server cmd[8]=--sender cmd[9]=-vvvvnlogDtpre.iLsfxC cmd[10]=. cmd[11]=/*

答案1
典型情况——我在这里发布帖子后就解决了这个问题（这个问题持续了整整一个晚上，并且经过了几个小时的调试......）
可以作为可选 Windows 10 功能启用的 OpenSSH 服务器似乎与 Cygwin 的 rsync 配合使用效果不佳。我通过 Cygwin 安装了 OpenSSH，一切都按预期连接。
rsync -nva --exclude={"/proc/*","/sys/*","/dev/*","/boot/*","/tmp/*","/run/*","/mnt/*"} -e "C:/cygwin64/bin/ssh.exe -i /cygdrive/h/ssh/BB8.OpenSSH.ppk" [email protected]:/* /cygdrive/h/Users/Matt/Documents/RPi3_Backup
