Snapshot an Azure VM Disk using PowerShell

Use the correct PowerShell command to stop and deallocate the VM that's provisioned with this lab.

In the Azure Portal, click All resources and copy the name of the pre-provisioned resource group.

In the Cloud Shell, create a new variable:

$rg = "<RESOURCE_GROUP_NAME>"

In the Azure Portal, copy the name of the VM disk and create a new variable:

$diskname = "<VIRTUAL_MACHINE_DISK_NAME>"

Create a variable for sasExpiryDuration:

$sasExpiryDuration = "3600"

In the Azure Portal, copy the storage account name, and create a new variable:

$storageAccountName = "<STORAGE_ACCOUNT_NAME>"

In the Azure Portal, copy the storage account key for key1, and create a new variable:

$storageAccountKey = "<KEY1_STORAGE_ACCOUNT_KEY>"

Create additional variables:

$storageContainerName = "container1"
$destinationVHDFileName = "disk1.vhd"
$useAzCopy = 1
$vmName = "winVM"

Stop the VM:

Stop-AzVM -ResourceGroupName $rg -Name $vmName

1. Once the VM has stopped, grant access to the disk:

$sas = Grant-AzDiskAccess -ResourceGroupName $rg -DiskName $diskName -DurationInSecond $sasExpiryDuration -Access Read

$destinationContext = New-AzStorageContext -StorageAccountName $storageAccountName -StorageAccountKey $storageAccountKey

1. Using AzCopy, send the snapshot to container1:

if($useAzCopy -eq 1)
{
$containerSASURI = New-AzStorageContainerSASToken -Context $destinationContext -ExpiryTime(get-date).AddSeconds($sasExpiryDuration) -FullUri -Name $storageContainerName -Permission rw
azcopy copy $sas.AccessSAS $containerSASURI

}else{

Start-AzStorageBlobCopy -AbsoluteUri $sas.AccessSAS -DestContainer $storageContainerName -DestContext $destinationContext -DestBlob $destinationVHDFileName
}
