Question

我正在尝试使用“按需付费”订阅中的Recovery Services保管库进行Azure Resource Manager备份和还原。我正在使用非常简单的代码，据我所知，它是出于MS文档的。我可以获得一个保险库对象，我可以获得一个容器，但是当我尝试从任何容器中获取任何项目时，Get-AzureRmRecoveryServicesBackupItem总是不返回任何内容，即使我知道其中有项目并且Azure RM GUI确认了这一点。 “什么都不返回”意味着如果我将结果赋给变量它是空的/ null，如果我尝试输出到控制台则没有输出。

我有两个不同的订阅，具有不同的保管库，虚拟机和备份项以及来自两台不同的计算机的结果相同。我在一台机器上重新安装了模块，另一台机器上从头开始安装模块。使用-Debug开关为Get-AzureRmRecoveryServicesBackupItem命令显示正在返回的项目，其结果为OK，没有错误。 Powershell代码显示在下面，然后出现-Debug输出。踢球者，这个确切的代码工作于2/7/17，没有开玩笑。我现在关注的是想法，所以任何帮助都会受到赞赏。

更新：我们发现当我们为Get-AzureRmRecoveryServicesBackupContainer使用-FriendlyName参数时会出现问题，但是如果我们通过管道输出| Where-Object {$ _.FriendlyName -eq $ vmName}问题不会发生。我们已经开了一个MSFT案例。

$vaultName = 'somevault'
$resourceGroupName = 'somerg'
$vmName = 'testvm'

$vault = Get-AzureRmRecoveryServicesVault -Name $vaultName -ResourceGroupName $resourceGroupName;
Set-AzureRmRecoveryServicesVaultContext -Vault $vault

$container = Get-AzureRmRecoveryServicesBackupContainer  -ContainerType AzureVM –Status Registered -FriendlyName $vmName
#output of this cmdlet is empty
Get-AzureRmRecoveryServicesBackupItem –Container $container  -Debug

调试输出：

有相同的问题（也在各种PC上）并通过传递不同的参数集来解决它。我没有使用Get-AzureRmRecoveryServicesBackupContainer来获取对容器的引用。相反，我直接使用容器名称调用Get-AzureRmRecoveryServicesBackupItem。这仅在您传递参数-BackupManagementType AzureVM时才有效。

Login-AzureRmAccount
Select-AzureRmSubscription -SubscriptionId <myguid>

Get-AzureRmRecoveryServicesVault -Name "myvaultname" | Set-AzureRmRecoveryServicesVaultContext
$item = Get-AzureRmRecoveryServicesBackupItem -BackupManagementType AzureVM -WorkloadType AzureVM -Name "myname"
$latestRecoveryPoint = Get-AzureRmRecoveryServicesBackupRecoveryPoint -Item $item | Sort-Object RecoveryPointTime -Descending | Select-Object -First 1

如果省略-Name，则会返回一个包含所有名称的列表。

当项目存在时，Get-AzureRmRecoveryServicesBackupItem不返回任何内容
