问题原因
管理员使用服务帐户登录到服务器进行交互式会话，然后注销后，通常会发生此问题。此活动强制在该帐户的配置文件中卸载注册表项。这种情况使密钥无法供将来使用，并且 Acronis Cyber Backup 无法访问它们。
有关详细信息，请参阅此Microsoft 支持文章
解决方法
禁用注销后卸载注册表项的 Windows 用户配置文件服务功能。为此，请按照下列步骤操作：
1.在受影响的服务器上打开组策略编辑器 （Gpedit.msc）
2.打开以下路径中的 UserProfiles 文件夹：计算机配置>管理模板>系统>用户配置文件
3.找到在用户注销时不强制卸载用户注册表设置，并将该设置更改为启用
4.重新启动 Acronis Managed Machine Service（开始 -> 运行 ->键入 services.msc ->在服务列表中找到 Acronis Managed Machine Service，右键单击它并选择重新启动）
