Backup / DR / BC
The course is part of these learning paths
This course provides an introductory tour of Azure Storage Solutions such as its SQL offerings (SQL DB and third-party offerings of MySQL), managed NoSQL databases (DocumentDB and MongoDB), managed Redis Cache service, Azure Backup (backup-as-a-service), Site Recovery (for handling disaster recovery) and StorSimple (a hybrid cloud storage solution).
- Understand what SQL DB is and how to get started using it
- Learn the options offered by Azure for managed MySQL
- Understand what DocumentDB and MongoDB are and how to get started using them

Welcome back, we are now ready to look at Site Recovery.
What is Site Recovery?
Site recovery is a disaster recovery-as-a-service product.
Which means it is a platform for you to manage your disaster recovery needs.
We covered Backup earlier, which is about data. Disaster recovery is about resources, systems and what order to stand you systems up when a failover happens.
Site Recovery also is a good tool to use in replicating systems to and recovery in Azure - this could be a DR scenario or maybe even a migration from your on-premise environment to running in Azure.
Site Recovery can also replicate on-premises VMs to Azure.
You can also set your system dependencies to orchestrate the step order your recovery will follow.
Site Recovery allows you to failover from the primary site to Azure or to a secondary site.
Also in the Portal you can monitor the status of replication and backup jobs, letting you know when something is wrong.
Site Recovery is about replicating your primary site and its systems in Azure or to a secondary site.
It can replicate VM's that are On-Premise – VMWare or Hyper-V VMs and even physical machines with either Windows or Linux on them.
If the replicas are going to Azure, they are stored in storage until they need to be brought online, then they are stood up as virtual machines at that time.
Site Recovery has a pretty extensive list of the types of workloads it can replicate.
As you can see, Active Directory, IIS, SQL Server, Sharepoint, Exchange, SAP, File Servers, Oracle, Linux, Citrix and even more.
This means if you have the machine or virtual machine running on-premise there is a good chance Site Recovery can replicate it to Azure for you.
As mentioned earlier, Site Recovery can be a great tool for migrating systems.
You can migrate physical servers or VM's to Azure.
Migrate from one Azure region to another.
Or even migrate AWS windows VMs to Azure – currently you can’t migrate Linux machines from AWS.
Recovery plans allow you to define machines that are related, for example a sharepoint farm will have a sql server and some web servers – which need to be grouped for a recovery scenario.
Once machines are grouped, you can then define the dependencies they may have.
For example, with a Sharepoint farm you would want to bring the database up before the web servers.
Once all the replicas and recovery plans are created you can test the recovery plan and verify the machines work. Then tear them down after you confirm the test is good.
