私はpowershellスクリプトを初めて使用しますが、スクリプトを少し編集して助けてください。基本的に、ハイパーv.Windows 2012/2012 r2上のすべてのサーバーのバックアップを自動的に作成するスクリプトをスケジュールしたいと考えています。基本的にユーザーにパラメーターを指定するように求めるコードを取得した後、バックアップを取ります。私が整理したことは、2つのことができるということです。1）ハイパーv上のすべてのvm名を含む.txtファイルを作成しますが、新しいvmを追加するたびにそのファイルを更新すると、多忙になります. だから私はこれをしたくありません。2) ユーザーからの入力を受け取る機能を削除し、「get-vm」コマンドをどこかに追加できますか? しかし、私はこれを行うことができません:/誰かが私がそれを行うのを手伝ってくれますか? 以下は私が使いたいコードです。

.SYNOPSIS
Export virtual machines
.DESCRIPTION
This utility will export virtual machines to a target destination. By default
it will create a folder using the format:
Weekly_Year_Month_Day_HourSecond
The script will delete the oldest folder once 4 subfolders have been created.
Use the -Monthly parameter to do the same thing but for folders that begin
with Monthly, i.e. Monthly_Year_Month_Day_HourSecond.
Because the export process can be time consuming, you can use the -AsJob parameter
which will be passed to Export-VM. You will then get PowerShell background jobs
which you can manage with the standard job cmdlets.
This script must be run as an administrator in an elevated session.
.PARAMETER VM
A comma separated list of virtual machines. You can also pipe Get-VM into
this command. This parameter has an alias of Name.
.PARAMETER Path
The path to the top level backup or export folder.
.PARAMETER Monthly
Run the script in Monthly mode
.PARAMETER AsJob
Export virtual machines using background jobs
.EXAMPLE
PS C:\> get-vm chi-dc01,chi-dc02 | c:\scripts\ScheduledExport.ps1 -path e:\export
Get the virtual machines, CHI-DC01 and CHI-DC02 and pipe them to the script which will
export them to the given folder.
.EXAMPLE
PS C:\> c:\scripts\ScheduledExport.ps1 "CHI-DC01","CHI-FP01" -path E:\Export -asjob
Export virtual machines CHI-DC01 and CHI-FP01 to a weekly folder under E:\Export.
.EXAMPLE
PS C:\> get-content c:\work\vms.txt | c:\scripts\ScheduledExport.ps1 -asjob -monthly
Read the text file, vms.txt, and pass each virtual machine name to the script. This will
use the Monthly backup folders. Exports will be done as jobs.
