azure - 将 VHD 从 Azure 磁盘复制到 Azure 存储帐户

Question

我有一个Windows 10系统的Azure磁盘。我希望此磁盘必须转换为 VHD，并且应该在 Azure 存储帐户中可用。

简单地说，我希望我的 Azure VM 数据磁盘存在于 Azure 存储 BLOB 中，而无需将 VHD 下载到我的基础计算机上。是否可以。如果是的话，请指导我。

任何人都可以帮助我吗？

谢谢

是的，这是可能的。您可以将托管磁盘复制到VHD文件中并将其存储在存储中。以下是通过 PowerShell 执行的示例代码:

#Provide the subscription Id of the subscription where managed disk is created
$subscriptionId = "yourSubscriptionId"

#Provide the name of your resource group where managed is created
$resourceGroupName ="yourResourceGroupName"

#Provide the managed disk name 
$diskName = "yourDiskName"

#Provide Shared Access Signature (SAS) expiry duration in seconds e.g. 3600.
#Know more about SAS here: https://learn.microsoft.com/en-us/Az.Storage/storage-dotnet-shared-access-signature-part-1
$sasExpiryDuration = "3600"

#Provide storage account name where you want to copy the underlying VHD of the managed disk. 
$storageAccountName = "yourstorageaccountName"

#Name of the storage container where the downloaded VHD will be stored
$storageContainerName = "yourstoragecontainername"

#Provide the key of the storage account where you want to copy the VHD of the managed disk. 
$storageAccountKey = 'yourStorageAccountKey'

#Provide the name of the destination VHD file to which the VHD of the managed disk will be copied.
$destinationVHDFileName = "yourvhdfilename"

#Set the value to 1 to use AzCopy tool to download the data. This is the recommended option for faster copy.
#Download AzCopy v10 from the link here: https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10
#Ensure that AzCopy is downloaded in the same folder as this file
#If you set the value to 0 then Start-AzStorageBlobCopy will be used. Azure storage will asynchronously copy the data. 
$useAzCopy = 1 

# Set the context to the subscription Id where managed disk is created
Select-AzSubscription -SubscriptionId $SubscriptionId

#Generate the SAS for the managed disk 
$sas = Grant-AzDiskAccess -ResourceGroupName $ResourceGroupName -DiskName $diskName -DurationInSecond $sasExpiryDuration -Access Read 

#Create the context of the storage account where the underlying VHD of the managed disk will be copied
$destinationContext = New-AzStorageContext -StorageAccountName $storageAccountName -StorageAccountKey $storageAccountKey

#Copy the VHD of the managed disk to the storage account
if($useAzCopy -eq 1)
{
    $containerSASURI = New-AzStorageContainerSASToken -Context $destinationContext -ExpiryTime(get-date).AddSeconds($sasExpiryDuration) -FullUri -Name $storageContainerName -Permission rw
    $containername,$sastokenkey = $containerSASURI -split "\?"
    $containerSASURI = "$containername/$destinationVHDFileName`?$sastokenkey"
    azcopy copy $sas.AccessSAS $containerSASURI

}else{

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

但在我的测试中，当您使用azcopy命令时，VHD文件出现问题。命令 Start-AzStorageBlobCopy 运行良好。因此，我向您推荐命令 Start-AzStorageBlobCopy。有关更多详细信息，请参阅Export/Copy the VHD of a managed disk to a storage account in different region with PowerShell .
