当我查看日志文件时，我想从服务器备份到本地 bu，它从 New-PSDrive 给出错误。

LocalBackup 文件中的错误部分：

挂载备份源

New-PSDrive ：指定的驱动器根目录“B”不存在，或者不是文件夹。

错误：未指定目标目录。

   Simple Usage :: ROBOCOPY source destination /MIR

         source :: Source Directory (drive:\path or \\server\share\path).
    destination :: Destination Dir  (drive:\path or \\server\share\path).
           /MIR :: Mirror a complete directory tree.

For more usage information run ROBOCOPY /?

**** /MIR 可以删除和复制文件！

卸载备份源

我是从 Internet 搜索的系统中的管理员，并绕过执行策略和凭据，它看起来不错，但仍然无法正常工作。

代码部分：

 # @(DstName,Path)

 $BackupDestinations =   @(

 , @('test2','\\srvr0002\TEMP\trying2')
                          )

 $BackupSources = @(
 , @('abcde','C:\Temp\ProjectCopy\Backup\Archives\Batch','Batch')
 , @('defgh','C:\Temp\Project - Copy\Backup\Archives\WinCCTag','test2')
                   )
 $LogPath = "C:\Temp\trying2adm_trerulug"

 $LogVersion = 50

 If (-Not (Test-Path $LogPath)){mkdir $LogPath}
 While ($LogVersion -gt 0)
 {
 $OldLogfile = "LocalBackup.$LogVersion.log"
 $Logfile = "LocalBackup.$($LogVersion-1).log"

 echo $null > $LogPath\$Logfile

 Function Write-Log{

 $RoboArgs =

您的问题是由您构建$BackupDestinations&$BackupSources集合的方式引起的。你没有数组数组……你有一个字符串数组。循环中$BckSrc[0]当前项目的第一个字母也是如此foreach。[咧嘴笑]

要么切换到使用哈希表，要么使用,数组运算符强制将子数组添加为子数组而不是项目列表。

如果你想坚持使用数组，请使用这样的东西 [注意每个子数组前的前导逗号] ...

$BackupSources = @(
    , @('abcde','C:\Temp\ProjectCopy\Backup\Archives\Batch','Batch')
    , @('defgh','C:\Temp\Project - Copy\Backup\Archives\WinCCTag','test2')
    )

使用以下代码，并且没有使用列表中名称的 PSDrive，并且目标目录已经创建 --- 没有关于创建或删除有问题的 PSDrive 的错误消息。

$BackupDestinations =   @(
, @('Batch','\\srvr0001\TEMP\trying3')
, @('test2','\\srvr0002\TEMP\trying2')
                        )

$BackupSources = @(
, @('abcde','C:\Temp\ProjectCopy\Backup\Archives\Batch','Batch')
, @('defgh','C:\Temp\Project - Copy\Backup\Archives\WinCCTag','test2')
                )

Foreach ($BkpSrc in $BackupSources)
    {
    New-PSDrive -Name $BkpSrc[0] -Root $BkpSrc[1] -PSProvider FileSystem #-WhatIf
    }

Get-PSDrive | Out-Host

'=' * 20 | Out-Host

#<#
Foreach ($BkpSrc in $Backupsources)
    {
    Remove-PSDrive -Name $BkpSrc[0]
    pause
    }
Get-PSDrive
#>

所以......你的代码的哪一部分产生了你在原始帖子中列出的错误？
