我想使用 Veeam 的免费版本在 Windows Hyper-V 2016 服务器上备份我的虚拟机。该工具的免费版本不提供定期备份的工具，因此我一直在寻找一种将其 API 与任务调度程序结合使用的方法。

在寻找解决方案的过程中，我遇到了这篇文章，其中包含了我所需要的所有详细信息：

https://blog.mwpreston.net/2015/04/29/scheduling-veeam-backup-free-edition-backups/

Param(
  [Parameter(Mandatory=$true)][string]$VM,
  [Parameter(Mandatory=$true)][string]$Destination,
  [Parameter(Mandatory=$true)][ValidateSet(0,4,5,6,9)][int]$Compression,
  [bool]$DisableQuiesce=$true,
  [Parameter(Mandatory=$true)][ValidateSet("Never","Tonight","TomorrowNight","In3days","In1Week","In2Weeks","In1Month")][string]$Autodelete
)
#Load Veeam Toolkit
& "C:\Program Files\Veeam\Backup and Replication\Backup\Initialize-VeeamToolkit.ps1"
#Validate any parameters
$vmentity = Find-VBRViEntity -Name $VM 
if ($vmentity -eq $null)
{
  Write-Host "VM: $VM not found" -ForegroundColor "red"
  exit
}
if (-Not (Test-Path $Destination))
{
  Write-Host "Destination: $vmname not valid" -ForegroundColor "red"
  exit
}
if ($DisableQuiesce -eq $true)
{
    Start-VBRZip -Entity $vmentity -Folder $destination -Compression $Compression -AutoDelete $Autodelete -DisableQuiesce
}
else
{
    Start-VBRZip -Entity $vmentity -Folder $destination -Compression $Compression -AutoDelete $Autodelete
}

但是，此页面上的 sript 仅支持备份单个 VM。我可以创建许多这样的脚本，但是最好有一个循环通过 VM 的脚本。

我想这就像循环遍历所有 VM 一样简单，但由于我没有使用 powershell 脚本的经验，也没有使用 Veeam，我正在寻找一些帮助/帮助来修改脚本以备份所有 VM。该页面的评论中有一些关于此的讨论，但似乎该博客文章已经更新，因此它不直接适用。

例如这样的：

(get-vm -ComputerName YOURSERVERFQDN | foreach { $_.Name }) -join "`",`"" | Tee-Object -Variable VMNames | Out-Null

额外的好处是在失败时添加某种电子邮件通知，但这有点超出了这个问题的主题。

复活一个老问题，但显然 Q 有很多观点，所以我想我应该分享我正在工作的脚本的最终版本。这是基于我在某处找到的原始脚本的不同版本，为我的目的而修改的。

它不是超级优雅，但它可以完成工作，如果失败，它会通过电子邮件发送一些方便的错误消息。

  [Parameter(Mandatory=$false)][string]$hostname = 'yourhostname',
  [Parameter(Mandatory=$false)][string]$BackupDestination = '\\yourdestination',

  [bool]$DisableQuiesce=$false,
  [ValidateSet("Never","Tonight","TomorrowNight","In3days","In1Week","In2Weeks","In1Month")][string]$Autodelete = "Tonight",
  [bool]$EnableNotification=$true,
  [string]$SMTPServer = 'smpt.yourmailserver.com'
