When experimenting in my lab environment I want to create a backup of the virtual machines. The following PowerShell script will do just that. I assume you’ve already setup your PowerShell to work with azure by doing the following:
- Setup the Azure PowerShell cmdlets (see: https://azure.microsoft.com/en-us/downloads/)
- imported your Publish Settings File (see Get-AzurePublishSettingsFile and Import-AzurePublishSettingsFile)
- Defined which storageaccount to use with Set-AzureStorageAccount
- Shutdown all the Virtual Machines
Import-Module Azure -ErrorAction Stop
$backupContainerName = "backups"
function Backup-Lab
{
$vms = Get-AzureVM
if (! (Get-AzureStorageContainer -Name $backupContainerName -ErrorAction SilentlyContinue) )
{
New-AzureStorageContainer -Name $backupContainerName -Permission Off
}
foreach ($vm in $vms)
{
Write-Host "backing up machine: " $vm.Name
$disks = @()
$disks += $vm | Get-AzureOSDisk
$disks += $vm | Get-AzureDataDisk
foreach($disk in $disks)
{
$DiskBlobName = $disk.MediaLink.Segments[-1]
$DiskContainerName = $disk.MediaLink.Segments[-2].Split('/')[0]
Write-Host "disk: " $disk.DiskName
#Start an asynchronous copy of the VHD to our backup destination
Start-AzureStorageBlobCopy -SrcContainer $DiskContainerName -SrcBlob $DiskBlobName -DestContainer $backupContainerName -DestBlob $DiskBlobName
#Wait for the copy to complete
Get-AzureStorageBlobCopyState -Blob $DiskBlobName -Container $DiskContainerName -WaitForComplete
}
}
