集中式 powershell 备份脚本

我们需要一个 powershell 脚本来从 3 个远程服务器备份文件夹：

服务器1 服务器2 服务器3

每个远程服务器上的源路径相同：c:\backupfiles

发送到包含每个文件夹当天日期的中央本地文件夹：c:\allbackups\server1<DATE> c:\allbackups\server2<DATE> c:\allbackups\server3<DATE>

最干净的方法是什么？谢谢，

这是完成这项工作的方法。[咧嘴笑] 它比所要求的要多一点，但由于缺乏适当的错误处理，因此尚未完全填写。无论如何......这是它的作用......

  • 创建服务器计算机列表
  • 设置各种常量
  • 创建目标根目录
    这里是一个“缺乏错误处理”的点 - 没有检查确保该目录已创建并且可写。
  • 遍历计算机列表
  • 检查远程源目录
  • 如果不存在，则在屏幕上
    另一个缺少的地方写入警告。您可能需要将缺少的源添加到 $Var 或错误文件中。
  • 如果是的话...
  • 建立完整备份目标目录
  • 创建它并忽略任何错误，
    这又是一个糟糕的错误处理。[叹息……]
  • 将参数构建robocopy到数组中
  • 使用上述参数 splat 调用 RC
    来查找Get-Help about_Splatting真正巧妙的功能。[咧嘴笑]
  • 完成对计算机列表的迭代

代码 ...

$ComputerList = @(
    'LocalHost'
    '127.0.0.1'
    $env:COMPUTERNAME
    )

# swap the `#` on these two lines to test "no source found"
$SourceDir = 'd$\Temp'
#$SourceDir = 'd$\Temp\NotThere'

$RootDestDir = "$env:TEMP\Backups"
if (-not (Test-Path -LiteralPath $RootDestDir))
    {
    $Null = New-Item -Path $RootDestDir -ItemType 'Directory'
    }

$FileSpec = '*.*'

$TimeStamp = (Get-Date).ToString('yyyy-MM-dd')
$Subject = 'RC_Backup'
$LogFileName = -join ($Subject, '_-_', $TimeStamp, '.log')
$FullLogFileName = Join-Path -Path $env:TEMP -ChildPath $LogFileName


foreach ($CL_Item in $ComputerList)
    {
    $RemoteSourceDir = '\\{0}\{1}' -f $CL_Item, $SourceDir
    if (Test-Path -LiteralPath $RemoteSourceDir)
        {
        $FullDestDir = Join-Path -Path $RootDestDir -ChildPath ('{0}_-_{1}' -f $CL_Item, $TimeStamp)
        $Null = mkdir -Path $FullDestDir -ErrorAction 'SilentlyContinue'

        $RC_Params = @(
            $RemoteSourceDir
            $FullDestDir
            $FileSpec 
            # put your current options below
            "/Log:$FullLogFileName"
            '/NP'
            '/E'
            # comment out the next line to suppress on-screen output
            '/TEE'
            )
        robocopy $RC_Params
        }
        else
        {
        Write-Warning ('    [ {0} ] was not found on [ {1} ].' -f $RemoteSourceDir, $CL_Item)
        }

    } # end >>> foreach ($CL_Item in $ComputerList)

如果源不可达则输出...

WARNING:     [ \\LocalHost\d$\Temp\NotThere ] was not found on [ LocalHost ].
WARNING:     [ \\127.0.0.1\d$\Temp\NotThere ] was not found on [ 127.0.0.1 ].
WARNING:     [ \\MySysName\d$\Temp\NotThere ] was not found on [ ZK_01 ].

成功运行的截断输出......

答案2

这就是我的简单的想法。

$ServerList = @( Server1 Server2 Server3 )
$AllBackups = "c:\allbackups"
$TimeStamp = (Get-Date).ToString('yyyyMMdd')
$SourceFolder = "C$\backupfiles"

foreach ($server in ServerList) {
    Copy-Item -Path "\\$server\$SourceFolder" -Destination "$AllBackups\$server-$Timestamp" -Recurse
}
