使用PowerShell对磁盘做快照并复制到存储账户

使用PowerShell对磁盘做快照并复制到存储账户

以下 PowerShell 脚本先对指定的托管磁盘创建快照，再将快照导出成 VHD 文件，保存在指定的存储账户中

Connect-AzAccount -Environment AzureChinaCloud $SubscriptionId = "xxxxxxxx" Select-AzSubscription -Subscription $SubscriptionId #磁盘所在资源组的名称 $ResourceGroupName ="oldrg" #磁盘名称 $DiskName = "hademo_OsDisk_1_2f5ee787fc8e4c6faaa01e88b3369504" #根据磁盘制作的快照名称 $SnapshotName = "oldrgwinos" #导出时间 $sasExpiryDuration = "3600" #导出到目标存储账号的名称 $StorageAccountName = "myresourcegroup54248" #导出到目标存储账号的容器名称 $StorageContainerName = "vhds" #存储账户的密钥 $StorageAccountKey = '1zz2xxxxxxxxxxxx' #导出到目标存储账户容器的vhd名称 $DestinationVHDFileName = "newwinos.vhd" #快照所在的区域 $Location = "chinanorth2" #获取磁盘信息 $Disk = Get-AzDisk -ResourceGroupName $ResourceGroupName -DiskName $DiskName #根据磁盘创建快照 $Snapshot = New-AzSnapshotConfig -SourceUri $Disk.Id -CreateOption Copy -Location $Location New-AzSnapshot -Snapshot $Snapshot -SnapshotName $SnapshotName -ResourceGroupName $ResourceGroupName #获取快照的SAS $sas = Grant-AzSnapshotAccess -ResourceGroupName $ResourceGroupName -SnapshotName $SnapshotName -DurationInSecond $sasExpiryDuration -Access Read #获取目标存储账户的凭据信息 $destinationContext = New-AzStorageContext -StorageAccountName $StorageAccountName -StorageAccountKey $StorageAccountKey #开始拷贝 Start-AzStorageBlobCopy -AbsoluteUri $sas.AccessSAS -DestContainer $StorageContainerName -DestContext $destinationContext -DestBlob $DestinationVHDFileName #查看拷贝进度 Get-AzStorageBlobCopyState -Blob $DestinationVHDFileName -Container $StorageContainerName -Context $destinationContext -WaitForComplete #回收快照的SAS Revoke-AzSnapshotAccess -ResourceGroupName $ResourceGroupName -SnapshotName $SnapshotName #删除快照 Remove-AzSnapshot -ResourceGroupName $ResourceGroupName -SnapshotName $SnapshotName -Force

参考:

Get-AzStorageBlobCopyState

AzCopy

推荐使用7.3.0

快照SAS如下:

azcopy /source:/SourceSAS:"?sv=2017-04-17&sr=b&si=b8ff2e37-deb9-4e7f-9578-eee4f728fccb&sk=system-1&sig=MA88lxbyk0ExdIn17aj25vhSCciMmEDfQrbd4Hxjh3g%3D" /dest:f:\test\abcd.vhd

Azure CLI 以下 Azure CLI 脚本仅对指定快照生成 SAS Uri，并将快照导出成 VHD 文件至指定存储账户
