Tim Hilt's questions

我运行以下命令来备份我的主目录：

$ rsync -ahv \
      --info=progress2 \
      --partial \
      --exclude=.cache/ \
      --exclude=.miniconda3/ \
      --exclude=.thunderbird/ \
      --exclude=.vscode/ \
      --exclude=.cargo/ \
      /home/tim \
      /run/media/tim/Volume/Backups/Tim/2021-04-15/

但是，当命令完成时，我注意到我的所有文件都设置了可执行标志！例如，当查看我的Cheatsheets-directory 时：

$ ls -l /home/tim/Cheatsheets/
total 3932

而在备份目录中：

从rsyncs 手册页中，我看到-a我使用的标志是 的别名-rlptgoD，-p应该保留权限。这个命令我哪里出错了？

我按照本教程介绍了如何使用 ssh 设置 GCE-VM。但是，我似乎无法像视频中的那个人那样通过 ssh 成功连接！这是我尝试连接时的输出（IP 是虚构的）：

我试图解决的问题：

1. 在不同的区域（亚洲而不是欧洲）设置 VM
2. 使用不同的映像设置 VM（debian、ubuntu、minimal 和 standard）
3. 在 Windows 和 Linux 下尝试设置
4. enable-oslogin = TRUE项目范围和特定实例
5. 从公共 ssh-key 中删除主机部分
6. ssh [IP], ssh [USER_IN_KEY]@[IP],ssh [USER_ON_VM]@[IP]

我真的不知道在哪里寻找问题了！谁能给我一个关于我可以尝试什么或问题可能出在哪里的指针或建议？

谢谢！
