Good day

I am a Microsoft Partner and CSP, but am very new to Azure.

I've got a client with a single Windows 2008 R2 Server (no virtualization) which we would like to backup to Azure Site Recovery.

I would like to know what I will need:

- System Requirements
- Azure Service Modules needed (Backup, Site Recovery)
- Restoring process

Please can someone point me in the right direction.

Firstly, to highlight the difference between Azure Backup and ASR:


Azure Backup - The Azure-based service you can use to back up (or protect) and restore your data in the Microsoft cloud. Azure Backup enables Azure IaaS VM backup as well as replace your existing on-premises or off-site backup solution with a cloud-based solution that is reliable, secure, and cost-competitive. Learn more about Azure Backup.


Azure Site Recovery - Contributes to your BCDR strategy by orchestrating replication of on-premises virtual machines and physical servers. You replicate servers and VMs from your primary on-premises datacenter to the cloud (Azure), or to a secondary datacenter. Learn more about Azure Site Recovery.


You can recover the machine (or data) by using either Azure Backup or ASR, the latter provides you fail back option.


You could use Azure Backup Server to protect Windows Server 2008 R2 (Volume, share, folder, file, system state/bare metal) using Azure backup.

Refer Azure Backup Server protection matrix for the supported Operating Systems.


Take a look into the instructions outlined in the documents below for the backup and restoration process:

Additionally, find the list of supported Operating System (for replicated machines) by ASR below:


64-bit Windows Server 2016 (Server Core, Server with Desktop Experience), Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2 with at least SP1. Windows 2016 Nano Server isn't supported. So, you should at least have 2008 R2 with SP1 and above.


You may refer the step-step instructions outlined in this document Set up disaster recovery to Azure for on-premises physical servers for the setup.
