SharePoint recovery environment in Microsoft AzureDesign and build the

failover environment in

Microsoft Azure

q Create a virtual network in Microsoft Azure.

q Connect the on-premises network with the virtual network in Microsoft Azure with a site-to-site VPN connection. This connections uses a dynamic gateway in Microsoft

Azure.

q Deploy one or more domain controllers to the Microsoft Azure virtual network and configure these to work with your on premises domain. These DCs are catalog servers.

q Adapt the SharePoint farm for cloud services and availability sets.

q Deploy the SharePoint farm plus a file server to host file shares.

q Setup log shipping and DFSR between the on-premises environment and the Microsoft Azure-based recovery environment.

The configuration of Active Directory for this solution constitutes a hybrid deployment scenario in which Windows Server AD DS is partly deployed on-premises and partly deployed on Microsoft Azure Virtual Machines.

Important Before deploying Active Directory in Microsoft Azure, read Guidelines for Deploying Windows Server Active Directory on Microsoft Azure Virtual Machines

(http://msdn.microsoft.com/en-us/library/windowsazure/jj156090.aspx).

For complete guidance on designing and deploying Active Directory environments, see http://TechNet.microsoft.com.

SharePoint Disaster

Recovery to Microsoft

Azure

Example architectures for building a

recovery environment in Microsoft

Azure

Overview The disaster recovery environment for an on-premises

SharePoint 2013 farm can be hosted in Microsoft Azure. Microsoft Azure Infrastructure Services provides a secondary datacenter.

Pay only for the resources you use.

Small recovery farms can be scaled out after a disaster to meet scale and capacity targets.

The recovery farm in Microsoft Azure is configured as

identically as possible to the production on-premises farm. Same representation of server roles.

Same configuration of customizations.

Same configuration of search components (these can be on a smaller version of the production farm).

Log shipping and Distributed File System Replication (DFSR)

are used to copy database backups and transaction logs to

the Microsoft Azure farm. DFSR is used to transfer logs from the production environment to the recovery environment. In a WAN

scenario DFSR is more efficient than shipping the logs directly to the secondary server in Microsoft Azure.

Logs are replayed to the Microsoft Azure-based SQL Server computers.

Log-shipped databases are not attached to the farm until a recovery exercise is performed.

Failover procedures: Stop log shipping.

Stop accepting traffic to the primary farm.

Replay the final transaction logs.

Attach the content databases to the farm.

Start a full crawl.

Restore service applications from the replicated services databases.

Recovery objectives provided by this solution include: Sites and content

Search (re-crawled, no search history)

Services

Additional items that can be addressed by Microsoft

Consulting Services or a partner:q Synchronizing custom farm solutions

q Connections to data sources on premises (BDC and search content sources)

q Search restore scenarios

q Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO)

Cold standby environments take longer to start but are less

expensive The farm is fully built, but the virtual machines are stopped after the farm is created. You only pay

processing costs when the virtual machines are running, but storage and network data transfer costs

apply.

In the event of a disaster, all the farm virtual machines are started and patched.

Backups and transaction logs are applied to the farm databases.

Additional procedures for cold standby environments Turn on virtual machines regularly to patch, update, and verify the environment.

Run procedures to refresh DNS and IP addresses.

Setup SQL AlwaysOn after a failover.

This reference architecture includes two virtual machines configured as domain controllers. Each is configured as follows:

Size Small.

Operating system Windows Server 2012.

Role Active Directory Domain Services domain controller designated as a global catalog server. This configuration reduces egress traffic across the VPN connection. In multi-domain environment with high rates of change, configure domain controllers on premises to not sync with the global catalog servers in Microsoft Azure.

Data disks Place the Windows Server AD DS database, logs, and SYSVOL on Microsoft Azure data disks. Do not place these on the Operating System disk or the Temporary Disks provided by Microsoft Azure. This is important.

Role Install and configure Windows DNS on the domain controllers.

IP addresses Use dynamic IP addresses. This requires you to create a Microsoft Azure Virtual Network.
