Create a snapshot of a VM with PowerShell in Azure

Frequent Contributor

 

Hi Azure friends,

 

I used the PowerShell ISE for this configuration. But you are also very welcome to use Visual Studio Code, just as you wish. Please start with the following steps to begin the deployment (the Hashtags are comments):

 

#The first two lines have nothing to do with the configuration, but make some space below in the blue part of the ISE

Set-Location C:\Temp
Clear-Host

 

#So that you can carry out the configuration, you need the necessary cmdlets, these are contained in the module Az (is the higher-level module from a number of submodules)

Install-Module -Name Az -Force -AllowClobber -Verbose

 

#Log into Azure
Connect-AzAccount

 

#Select the correct subscription

Get-AzContext

Get-AzSubscription

Get-AzSubscription -SubscriptionName "your subscription name" | Select-AzSubscription

 

#Set some parameters
$resourceGroupName = 'tw-rg01' 
$location = 'westeurope' 
$vmName = 'tw-winsrv'
$snapshotName = 'mySnapshot'

#Get the VM
$vm = Get-AzVM -ResourceGroupName $resourceGroupName -Name $vmName

#Create the snapshot configuration
$snapshot =  New-AzSnapshotConfig -SourceUri $vm.StorageProfile.OsDisk.ManagedDisk.Id -Location $location -CreateOption copy

#Take the snapshot
New-AzSnapshot -Snapshot $snapshot -SnapshotName $snapshotName -ResourceGroupName $resourceGroupName

#Next steps in the Azure Portal
#Create a virtual machine from a snapshot by creating a managed disk 
#from a snapshot and then attaching the new managed disk as the OS disk
 
Now you have used the PowerShell to create a snapshot of  virtual machine! Congratulations!
