我想我明白了，但我想确定一下。
我们正在运行两个 Windows 2016 域控制器 (VM)，其中一个正在执行证书服务器的角色。我们每天执行系统状态备份并将它们卸载到远程位置。如果出于某种原因需要完全重建带有 CA 的域控制器，我假设我可以使用最新的系统状态备份来恢复 CA，并且现有的域控制器将更新重建的服务器所有其他广告信息。这是一个正确的假设还是我应该实施 CA 特定的恢复计划？
附加信息：我正在为部署在 50 多个断开连接的环境中的系统制定基线。在这一点上，向每个站点添加另一台服务器不是我的选择。我计划同时实施系统状态和特定于 CA 的备份计划来帮助恢复，这里有一些脚本是我拼凑起来的，以帮助手动检查和自动化日常流程。

我已经在实验室中测试了其中的大部分内容，并在我删除一两个服务器并尝试恢复之前让样片运行一段时间。如果有人有任何额外的建议，将不胜感激。
