[Azure]ARM模式托管磁盘的快照与还原[2]——删除与恢复

来源：互联网发布：浪迹知乎编辑：程序博客网时间：2024/05/17 05:59

本文中包含两个脚本，一个是删除托管磁盘快照的脚本，一个是使用托管磁盘快照还原磁盘的脚本。

比较简单，只是几个命令的调用，这里就不详细解释具体的语句意义了，大家直接看脚本吧：

删除快照的脚本：

param(      [Parameter(Mandatory = $true)]    [string]$SubscriptionName,       [Parameter(Mandatory = $true)]    [string]$ResourceGroupName,      [Parameter(Mandatory = $true)]    [string]$ManagedDiskName)[void](Select-AzureRmSubscription -SubscriptionName $SubscriptionName);$disk = Get-AzureRmDisk -ResourceGroupName $ResourceGroupName -DiskName $ManagedDiskName;if ($disk -eq $null){    Write-Host "Disk not found";    return;}$snapshots = Get-AzureRmSnapshot;$filteredSnapshots = @($snapshots | where {$_.CreationData.SourceUri -eq $disk.Id});Write-Host ("Snapshot found for disk {0}:" -f $ManagedDiskName) -ForegroundColor Yellow;$filteredSnapshots | select @{Name="Id"; Expression={$filteredSnapshots.IndexOf($_) + 1}}, @{Name="TimeCreated"; Expression={$_.TimeCreated.ToLocalTime()}}, Name | ft;$selection = (Read-Host "Please select the snapshot you want to delete, input 'a' if you want to delete all snapshots");If ($PSCmdlet.ShouldContinue("Confirm?", "=== Confirm delete Opeartion ===")){    if ($selection -eq "a")    {        foreach ($snapshot in $filteredSnapshots)        {            Write-Host ("Deleting snapshot {0}" -f $snapshot.Name) -ForegroundColor Yellow;            [void](Remove-AzureRmSnapshot -ResourceGroupName $snapshot.ResourceGroupName -SnapshotName $snapshot.Name -Force);            Write-Host ("Snapshot {0} deleted" -f $snapshot.Name) -ForegroundColor Green;        }    }    else    {        $selection = $selection - 1;        $snapshot = $filteredSnapshots[$selection];        Write-Host ("Deleting snapshot {0}" -f $snapshot.Name) -ForegroundColor Yellow;        [void](Remove-AzureRmSnapshot -ResourceGroupName $snapshot.ResourceGroupName -SnapshotName $snapshot.Name -Force);        Write-Host ("Snapshot {0} deleted" -f $snapshot.Name) -ForegroundColor Green;    }}

还原磁盘的脚本：

param(      [Parameter(Mandatory = $true)]    [string]$SubscriptionName,       [Parameter(Mandatory = $true)]    [string]$ResourceGroupName,      [Parameter(Mandatory = $true)]    [string]$ManagedDiskName,    [Parameter(Mandatory = $true)]    [string]$RestoredDiskName)[void](Select-AzureRmSubscription -SubscriptionName $SubscriptionName);$disk = Get-AzureRmDisk -ResourceGroupName $ResourceGroupName -DiskName $ManagedDiskName;if ($disk -eq $null){    Write-Host "Disk not found";    return;}$snapshots = Get-AzureRmSnapshot;$filteredSnapshots = @($snapshots | where {$_.CreationData.SourceUri -eq $disk.Id});Write-Host ("Snapshot found for disk {0}:" -f $ManagedDiskName) -ForegroundColor Yellow;$filteredSnapshots | select @{Name="Id"; Expression={$filteredSnapshots.IndexOf($_) + 1}}, @{Name="TimeCreated"; Expression={$_.TimeCreated.ToLocalTime()}}, Name | ft;$selection = (Read-Host "Please select the snapshot you want to restore");$selection = $selection - 1;$snapshot = $filteredSnapshots[$selection];$restoredDiskConfig = $null;if ($snapshot.OsType -eq $null){    $restoredDiskConfig = New-AzureRmDiskConfig -AccountType $snapshot.AccountType -Location $snapshot.Location -CreateOption Copy -SourceResourceId $snapshot.Id;}else{    $restoredDiskConfig = New-AzureRmDiskConfig -AccountType $snapshot.AccountType -OsType $snapshot.OsType -Location $snapshot.Location -CreateOption Copy -SourceResourceId $snapshot.Id;}Write-Host ("Restoring data to managed disk {0}" -f $RestoredDiskName) -ForegroundColor Yellow;[void](New-AzureRmDisk -DiskName $RestoredDiskName -Disk $restoredDiskConfig -ResourceGroupName $ResourceGroupName);Write-Host "Finished" -ForegroundColor Yellow;
