如何快速从一个Storage Account拷贝到另一个账号

当您有两个Storage Account的时候，怎样快速做到从一个账号拷贝到另一个账号呢。当拷贝的文件比较，例如100多G（VHD文件）。

http://code.msdn.microsoft.com/Windows-Azure-VHD-blob-5e40d0d4/sourcecode?fileId=67604&pathId=443692726 提供C#代码实现，实现原理是先下载，再上传。

如果使用PowerShell命令脚本来做，就会快，瞬间完成拷贝。

代码如下：

$StorageName1="<Storage Account>"
$StorageKey1="<Storage Key>"
$ContainerName1="vhds"
$BlobName1="eric***.vhd"
$StorageCtx1 = New-AzureStorageContext -StorageAccountName $StorageName1 -StorageAccountKey $StorageKey1 -Environment AzureChinaCloud
#$Container1 = Get-AzureStorageContainer -Name $ContainerName1 -Context $StorageCtx1 

$StorageName2="<Storage Account>"
$StorageKey2="<Storage Key>"
$ContainerName2="vhds"
$BlobName2="copied.vhd"
$StorageCtx2 = New-AzureStorageContext -StorageAccountName $StorageName2 -StorageAccountKey $StorageKey2 -Environment AzureChinaCloud
#$Container2 = Get-AzureStorageContainer -Name $ContainerName2 -Context $StorageCtx2

Start-CopyAzureStorageBlob -SrcBlob $BlobName1 -DestBlob $BlobName2 -SrcContainer $ContainerName1 -DestContainer $ContainerName2 -Context $StorageCtx1 -DestContext $StorageCtx2
