在Azure中创建虚拟机快照

Question

遵循本文(http://www.coreazure.com/snapshot-vms-in-azure-2/)，我试图从Azure门户使用powershell(PS)创建虚拟机的快照。这是我创建的用于拍摄快照的PS脚本

workflow snapshot1
{
   $subName = 'XYZ'
   $cred = Get-AutomationPSCredential -Name "[e-mail]" 
   Add-AzureAccount -Credential $cred
   Set-AzureSubscription -SubscriptionName $subName -CurrentStorageAccount 'storagename'
   $serviceName = "a1smallvm"
   $vm = Get-AzureVM –ServiceName $serviceName –Name "a1smallvm"
   $storageContainer = "backups"
   InlineScript {
      # Create a storage for putting the backups of OSDisk & DataDisks 
      New-AzureStorageContainer -Name $Using:storageContainer -Permission off
      # Stop VM if running
      $Using:vm | Stop-AzureVM -StayProvisioned
      $vm = Get-AzureVM –ServiceName $Using:serviceName –Name "a1smallvm"
      $vmOSDisk = $vm | Get-AzureOSDisk
      $vmDataDisks = $vm | Get-AzureDataDisk
      Write-output "OSDisk: $vmOSDisk"
      $storageAccountName = $vmOSDisk.MediaLink.Host.Split(‘.’)[0]
      Write-output "Data Disk: $vmDataDisks"
      Write-output "StorageAccountName: $storageAccountName"
      $vmOSBlobName = $vmOSDisk.MediaLink.Segments[-1]
      $vmOSContainerName = $vmOSDisk.MediaLink.Segments[-1].Split(‘/’)[0]
      Write-output "vmOSBlobName: $vmOSBlobName"
      Write-output "vmOSContainerName: $vmOSContainerName"
      # Backup the osblob and oscontainer
      Start-AzureStorageBlobCopy -SrcContainer $vmOSContainerName -SrcBlob $vmOSBlobName -DestContainer $Using:storageContainer
      Get-AzureStorageBlobCopyState -Container $Using:storageContainer -Blob $vmOSBlobName -WaitForComplete
      # Backup the dataBlob and dataContainer
      ForEach ($vmDataDisk in $vmDataDisks) {
        $vmDataBlobName = $vmDataDisk.MediaLink.Segments[-1]
        $vmDataContainerName = $vmDataDisk.MediaLink.Segments[-2].Split(‘/’)[0]
        Start-AzureStorageBlobCopy -SrcContainer $vmDataContainerName -SrcBlob $vmDataBlobName -DestContainer backups -Force
        Get-AzureStorageBlobCopyState -Container backups -Blob $vmDataBlobName -WaitForComplete
      }    
  }    
}

cmdlet

Start-AzureStorageBlobCopy -SrcContainer $vmOSContainerName -SrcBlob $vmOSBlobName -DestContainer $Using:storageContainer

抛出错误:

Error: Start-AzureStorageBlobCopy : Container name 'a1smallvm-a1smallvm-2015-08-11.vhd' is invalid. Valid names start and end with a lower case letter or a number and has in between a lower case letter, number or dash with no consecutive dashes and is 3 through 63 characters long.

容器名称'a1smallvm-a1smallvm-2015-08-11。我得到的vhd'遵循正确的命名格式，但仍然为什么它给出一个错误，说名称无效。虚拟机是从门户创建的，它是A1类型的虚拟机，操作系统是CentOS"OpenLogic 6.5"。知道怎么了吗?

下面是Write-output

的输出

OSDisk: Microsoft.WindowsAzure.Commands.ServiceManagement.Model.OSVirtualHardDisk
Data Disk: 
StorageAccountName: portalvhds14510n2y65vnh
vmOSBlobName: a1smallvm-a1smallvm-2015-08-11.vhd
vmOSContainerName: a1smallvm-a1smallvm-2015-08-11.vhd

正确的脚本:存储帐户名称必须相同，否则我们将不得不添加目标存储帐户的上下文。

$storageAccountName = $vmOSDisk.MediaLink.Host.Split(‘.’)[0] Set-AzureSubscription -SubscriptionName $subName -CurrentStorageAccount '$storagenameAccountName'

segment的索引应该是-2而不是-1$vmOSContainerName = $vmOSDisk.MediaLink.Segments[-2].Split(‘/’)[0]

Answer 1

我不是PowerShell专家(我相信有更好的方法)，但你可以这样做:

$vmOSContainerName = $vmOSDisk.MediaLink.AbsolutePath.Split('/')[1]

这将输出vhds，这是您的blob容器的名称。
