将远程 Linux 服务器备份到 Windows

Cygwin 具有 openssh（客户端和服务器）和 rsync，因此您当然可以使用它来创建一个 rsync 目标，就像在 linux 上一样。

我主要担心的是文件系统问题。Rsync 尝试同步元数据，而不是在单独的位置捕获它（喜欢tar或zip会这样做）。这意味着元数据与目标文件系统不兼容的地方，你会遇到问题。

• 两台机器上的用户可能不同
• NTFS 文件名比大多数 linux 文件系统有更多的限制。
• 我不知道如果 rsync 在 NTFS 上请求设备特殊文件会发生什么。

如果您尝试通过没有任何奇怪名称且所有权/权限不是什么大问题的网络文件夹进行同步，那么它应该可以正常工作。如果您正在尝试同步 linux 根文件系统并希望保留所有设备和权限，我认为 rsync 到 Windows 上可能会更成问题。

另一种方法是在 Windows 服务器内运行 linux VM。然后，您可以根据需要配置 VM。如果它只做一些非工作时间的文件传输，并且您有足够的 RAM，那么它根本不会影响 windows 服务器的性能。

如果您设置了一项服务，我认为 SSH 是首选，但它可能是 RSH 或其他服务，它就像通过定制 rsnapshot.conf 文件从源复制到目标一样简单。

rsnapshot 是一个基于 rsync 的文件系统快照实用程序。rsnapshot 可以很容易地通过 ssh 对本地机器和远程机器进行定期快照。该代码尽可能广泛地使用硬链接，以大大减少所需的磁盘空间。 Rsnapshot 完全用 perl 编写，没有模块依赖关系，并且已经在 5.004 到 5.16.3 版本中进行了测试。它应该适用于任何相当现代的 UNIX 兼容操作系统。

rsnapshot 如果安装在 linux 上会很棒，并且当从源备份到目标时，源基本上是挂载在 linux 上的任何东西。实现挂载在linux上不需要是本地磁盘。
