Backup in Azure IaaS?

Category: azure security

I have created six servers in Azure IaaS and Federated with Office 365. All works well! I don't want VM image backups as I trust Microsoft not to lose my VMs. But users can still lose files and an admin can delete the wrong accounts in AD so how should a Azure backup solution be created?

Currently, I'm considering creating a seventh server and simply install Backup Exec in it as I would have done in an on-prem solution.

How do the rest of you do backups in Azure IaaS?

Most people I talk to just use whatever backup solution they use on premise.

Ok. In an additional VM or back to an onprem solution?

Depends on the backup tool and the infrastructure on premise. What I've seen in some cases is actually backing up from an Azure VM to a hosted Backup Service.

I don't think I've seen from one Azure VM to another Azure VM though. (Admittedly, I tend to keep my nose out of infrastructure things though).

I guess one have to weigh speed vs traffic cost vs cost of storage. Ah well, I think I will go all in with Azure. But all eggs will be in that one basket...

Since the issue is related to Iaas, I have moved this thread to Virtual Machine forums for getting a better support.

Thanks for your understanding.

Since the VHDs are going to be stored in your storage account. you can download the VHD image from any storage explorer to on premise and mount it with Hyper-V manager.

Another way is, stop your VM and sysprep it and capture the image, and download the image from your blob storage to local machine and mount it using Hyper-V manager.

Coming to 2nd point, i understand you want to backup your virtual machine and restore after some time. If so it is easy task. You can simply save your work on VM and stop the VM and delete the VM. Since the disks are stored in to storage account, your disks (VHDs) will still be there in storage even after deleting the VM. if you want to back up them to local machine, you can simply download it and upload back through CS Upload when you want. If you want to keep that in storage it self, you can leave the disks in storage it self and when you are creating VM again you can create VMs based on the disks that exist in your storage account.

When you choose new VM option, azure site shows the available disks and you can select the disk you want to spin up the VM.

Hope it helps.
