Veeam Backup Free，Samba共享和PowerShell：拒绝访问

Question

我有：

ESXi主机包含一些虚拟机
Veeam Backup免费版安装在其中一台虚拟机上（Windows Server 2012 R2）
Debian主机上有samba

我成功了：

在debian机器上使用samba创建共享文件夹
使用Veeam Backup GUI手动备份到debian机器上的文件夹

我遇到麻烦：

从PowerShell脚本运行备份以便能够进行计划备份。

这篇关于Veeam论坛的topic建议

授予Veeam帐户以及给定共享的计算机帐户读/写权限

但我不知道如何将这些权限实际授予samba文件夹。

能否帮助我授予samba文件夹权限？

这是脚本：
