我有两台服务器，都是 Mandriva 2010.2，具有完全相同的 rdiff-backup(1.3.3) 版本和完全相同的 rsync。我曾经在 debian 中使用过 rdiff-backup，但从那时起我已经转移到不同的操作系统。当我现在尝试使用 rdiff-backup 时，我只会遇到很多错误。但是通过 rsync 连接工作得很好。
如下所示：
[root@localhost var]# rsync --rsh='ssh -p24752' -avz -e [email protected]:/var/test /var/backup 发送增量文件列表 drwxr-xr-x 4096 2012/06 /22 13:27:38 备份
发送 39 字节 接收 13 字节 104.00 字节/秒 总大小为 0 加速为 0.00
但这是当我尝试通过 rdiff-backup 运行它时发生的情况
[root@localhost var]# rdiff-backup --remote-schema 'ssh -C %s -p 24752' -v9 --print-statistics [email protected]::/var/test /var/backup

Remember that, under the default settings, rdiff-backup must be
installed in the PATH on the remote system. See the man page for more
information on this. This message may also be displayed if the remote
version of rdiff-backup is quite different from the local version (1.3.3).
当我使用以下命令字符串复制并粘贴连接失败时，它可以立即正常工作（已设置密钥对）
[root@localhost var]# ssh -C [email protected] -p24752

两台服务器都是根服务器，两组文件都存在。我尝试使用带有“-t -t”的 ssh 命令来解决标准输入错误，但这会导致 python 内存异常：/。
关于如何进行的任何想法？
编辑：这也是当我不使用自定义模式时它所做的（或多或少相同，但端口 22 拒绝连接，因为我们不使用它：P

问题是你的服务器正在运行 bash 作为 shell，而不是
rdiff-backup --server（它会理解它的'oh(crdiff_backup.connection'命令）。我的解决方案是：ssh -C %s -p 24752 rdiff-backup --serverrdiff-backup --server（如果您在脚本中使用它，这也会更安全一些）。
