1. Restore the VM from “Backup Item” in the Vault and select Restore Type as “Restore disks”.
2. Download the three .json files which have been created along with the VHD in the container of the storage account.
3. Login to Azure via PowerShell
PS C:\Windows\system32> Connect-AzAccount
4. Find the id of the availability set
PS C:\Windows\system32> Get-AzAvailabilitySet -ResourceGroupName "xxx"
5. Find the following information below from the .json files which were downloaded in Step.2
– VM-Size (e.g. Standard_DS2_v2_Promo)
– OS Disk URI (e.g. https://xxxxx/xxxxx/xxxx.vhd)
– NIC ID (e.g /subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.Network/networkInterfaces/xxx)
– Location (e.g. australiasoutheast)
6-1. Run the commands below if using unmanaged disk (Storage Account)
PS C:\Windows\system32> $vm = New-AzureRmVMConfig -VMName <VM-name> -VMSize <vm-size> -AvailabilitySetId <availability-set-id>
PS C:\Windows\system32> Set-AzureRmVMOSDisk -CreateOption "Attach" -VM $vm -VhdUri <osDiskURI> -Name <osDiskName> [-Windows | -Linux]
----- If Data Disks available -----
PS C:\Windows\system32> Add-AzureRmVMDataDisk -VM $vm -Name <DataDiskName> -VhdUri <DataDiskURI> -Lun <LUN#> -CreateOption Attach
-----------------------------------
PS C:\Windows\system32> Add-AzureRmVMNetworkInterface -VM $vm -Id <nicId>
PS C:\Windows\system32> New-AzureRmVM -ResourceGroupName <resourceGroupName> -Location <location> -VM $vm
6-2. Run the command below if using managed disk
#Provide the name of your resource group $resourceGroupName ='xxx' #Provide the name of the snapshot that will be used to create OS disk $snapshotName = 'xxx' #Provide the name of the OS disk that will be created using the snapshot $osDiskName = 'xxx' #Provide the name of the Nic $nicName = 'xxx' #Provide the name of the VM $myvm = 'xxx' #Provide the VM Size $vmsize = 'xxx' ########## $snapshot = Get-AzSnapshot -ResourceGroupName $resourceGroupName -SnapshotName $snapshotName $diskConfig = New-AzDiskConfig -Location $snapshot.Location -SourceResourceId $snapshot.Id -CreateOption Copy $disk = New-AzDisk -Disk $diskConfig -ResourceGroupName $resourceGroupName -DiskName $osDiskName $nic = Get-AzNetworkInterface -Name $nicName # If AvailabilitySet is configured $ava = Get-AzAvailabilitySet -ResourceGroupName $resourceGroupName $vm = New-AzVMConfig -VMSize $vmsize -VMName $myvm -AvailabilitySetId $ava.Id ## If AvailabilitySet is NOT configured #$vm = New-AzVMConfig -VMSize $vmsize -VMName $myvm # Set the VM configuration to point to the new disk Set-AzVMOSDisk -VM $vm -ManagedDiskId $disk.Id -Name $disk.Name -CreateOption Attach -Windows Add-AzVMNetworkInterface -VM $vm -ID $nic.Id New-AzVM -ResourceGroupName $resourceGroupName -VM $vm -Location $disk.Location
