使用 PowerShell 将托管磁盘的 VHD 导出/复制到不同区域中的存储帐户 (Windows)

此脚本将托管磁盘的 VHD 导出到不同区域中的存储帐户。 它首先生成托管磁盘的 SAS URI，然后使用该 SAS URI 将基础 VHD 复制到不同区域中的存储帐户。 使用此脚本将托管磁盘复制到另一区域以进行区域扩展。

必要时，请使用 Azure PowerShell 指南中的说明安装 Azure PowerShell 模块，然后运行 Connect-AzAccount -Environment AzureChinaCloud 创建与 Azure 的连接。 此外，用户配置文件的 .ssh 目录中需具备名为 id_rsa.pub 的 SSH 公钥。

如果没有 Azure 订阅，可在开始前创建一个试用帐户。

示例脚本

#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: /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
    azcopy copy $sas.AccessSAS $containerSASURI

}else{

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

脚本说明

此脚本使用以下命令生成托管磁盘的 SAS URI，然后使用该 SAS URI 将基础 VHD 复制到存储帐户。 表中的每条命令均链接到特定于命令的文档。
