rdiff-不允许备份操作

Question

目标

我试图在Python脚本中执行以下命令：

远程模式"ssh % -p1019 -i C:/-i/Adam/.ssh/private-passphrase rdiff-备份-服务器“C:/Users/Adam/Desktop pi@192.168.0.125：：/media/exthdd1 1/backup

我的源目录来自Windows操作系统，我的目标目录是基于Debian的系统。

问题

我得到了这个输出：

Fatal Error: Lost connection to the remote system`

试图解决

• 我以为是权限，但我的目标目录是777。
• 我试过以管理员的身份运行CMD
• 将我的Windows用户帐户添加到用户组用户
• 在设置Cygwin到sshd服务的中途，但是一直收到“错误1053:无法启动服务”，于是放弃了。我试着这么做是因为我认为SSH别名可以简化命令，并查看它是否让我得到了任何东西，关于占位符%s的一些东西让我感到恶心，所以我想如果我能够使用它，我可能会得到一些东西。有没有人认为SSH化名还值得继续研究？

Answer 1

问题确实出现在/etc/fstab中--我将gid和uid值添加到目标驱动器的用户pi行中。

Answer 2

Errno 1是“不允许的操作”，所以它绝对是权限，而且显然是Linux端的权限。

在Linux方面，您已经检查了目标目录为777，但还需要确保运行rdiff-backup的用户能够导航到目录下。检查/media/exthdd1和/media。
