Azure ASR’s SLA-backed enhanced VMware to Azure solution is now ready to replicate your on-premises workloads to Azure
You heard right. Microsoft has launched an enhanced version of its Azure Site Recovery (ASR) targeted especially for VMware customers.
The concept of ASR is very simple: organisations will be able to replicate their VMware virtual machines (VMs) to Azure, update and then run them in Azure as a disaster recovery option. They will be charged a small amount by VM but won’t have to pay for compute or storage until the VM is up and running in Azure.
To note, Azure Site Recovery, as part of Microsoft Operations Management Suite (OMS), enables your organisation to gain control and manage your workloads no matter the source: Azure, AWS, Windows Server, Linux, VMware or OpenStack.
Some of the key ASR characteristics:
- With non-disruptive recovery testing, you can easily test the failover of your VMware virtual machines to Azure within minutes, and validate your workload’s performance in Azure, without impacting on-going replication or the production workload.
- With ASR-integrated failback, start replicating your Azure virtual machines back to your on-premises ESXi environment, and failback to the original or an alternate location when your on-premises site is once again available for use.
- Heterogeneous workload support, automated VMware vCenter Server discovery
- Continuous data protection (CDP), one-click failovers with ASR Recovery Plan
- Rich health monitoring and e-mail notifications.
I’ve been working with ASR for a while and I definitely recommend it.
Ready to start using ASR? Check out additional product information, to start replicating your workloads to Microsoft Azure using Azure Site Recovery today. You can use the powerful replication capabilities of Site Recovery for 31 days at no charge for every new physical server or virtual machine that you replicate.

I have been contacted by some people asking about backup issues they are experiencing on Windows Server 2012 . The issue is related with the Microsoft November update release KB3000853.
My recommendation is to remove the update until Microsoft fix the issue as it affected Microsoft and third party backup products.
As per Taylor Brown’s (Hyper-V Program Manager) blog,
“We are getting reports that some customers are seeing backup jobs fail after installing the latest Windows Updates including the November rollup (http://support.microsoft.com/kb/3000853).
We believe there is an issue with the KB3000853 update and are working to fix it as quickly as possible, in the interim downloading and applying http://support.microsoft.com/kb/2996928/ should address the problem”
Saturday 22nd November
Infrastructure Saturday is a day long event for south east Queensland based IT Professional that work with Microsoft products. This event is an educational, informative & lively day filled with sessions about Microsoft technologies.
Location: Microsoft office, Brisbane, QLD. http://www.infrastructuresaturday.com/
Topics covered in my Session: What’s New in Hyper-V vNext?
- New Virtual Machine Upgrade Process
- New Integration Components installation method
- Secure Boot for Linux
- Distributed Storage Quality of Service (QoS)
- Hyper-V Backup
- Hyper-V Virtual Machine Configuration
- Cluster OS Rolling Upgrade
Microsoft just released a critical fix for hyper cluster that have been backed up by System Center DPM
“Physical Disk resource move during the backup of a Cluster Shared Volume (CSV) may cause resource outage”.
If you have configured a Windows Server 2012-based Hyper-V failover cluster CSV and your backup software perform the backup by using snapshots and the Physical Disk resource is moved to another node in the cluster, the Physical Disk resource may fail to come online if the backup of the CSV is in progress. As a result, virtual machines that rely on the CSV may crash.
A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem.

DPM design for Hyper-V :
- Incremental Backups Only – full only once
- No More Backup Window – online backups
- Application consistency via VSS
- Protect Live Migration VMs in CSV clusters
- Protect whole VM, recover individual items
- Auto Protection of new VMs
- Routine backups – nightly or more frequently
Strategy to Deply DPM 2010 in Hyper-V/CSV environment :
- Identify Project Requirements and scope
- Simulate using Hyper-V Calculator
- Review Hyper-V design guidelines & Best Practices
- Acquire VSS Hardware Provider & check environment with SDPM SAN Testing Tool:
- Verify that the SAN supports hardware snapshots & is certified for DPM.
- Install the VSS hardware provider
- Self Certifying your SAN. If your SAN is not in the certified list & you have a SAN, run the SCDPM SAN Testing Tool : StartCSVTests.cmd /run ( to be realeased yet )
- Validate a Pilot Environment
- Ready for Deployment
- Integration components should be updated on both VMs.
- Ensure that Live Migration is functional
2. Deploy : Protected CSV server
- Install all recommended prerequisites:
|General Prerequisite||Install the integration components on the guests. For more information, see Install a Guest Operating System (http://go.microsoft.com/fwlink/?LinkId=165041).|
|Microsoft Windows Server 2008 SP2||Install Microsoft Windows Server 2008 SP2 OR Install the Microsoft Hyper-V prerequisites (http://go.microsoft.com/fwlink/?LinkID=133781).|
|Microsoft Windows Server 2008 R2||Install the following on the host computer:KB975354 (http://support.microsoft.com/kb/975354)KB975921 (http://support.microsoft.com/kb/975921)|
- Failover Cluster Validation
- Enable Automount : Enable Auto mount on the host for successful child partition backups : MOUNTVOL /E
- Install Hardware Provider:Ensure that VSS hardware providers are installed : vssadmin list providers
- Validate Hardware snapshots
- Use DSConfig Tool to serialize backups (for software snapshots providers only) :
· Problem:With software snapshots, simultaneous triggering of VM backups (especially scale deployments) will cause backup jobs to time out and fail.
· Enable Per CSV LUN Serialization:This serialization limits the number of virtual machine backups happening on a single CSV LUN.Create a DataSourceGroups.xml file by running the DSConfig.ps1 script on any one node of a cluster containing CSV.Place the file in the DPM server at %PROGRAMFILES%\Microsoft DPM\DPM\Config.Repeat step 1 for every cluster that is protected by a DPM server.The DataSourceGroups.xml file needs to be updated only when virtual machines are added, deleted, or modified in the cluster and protection is configured for them.
3. Deploy : DPM 2010 server
- Enable Hyper-V Role on DPM Server :DPM supports item-level recovery (ILR), which allows you to do granular recovery of files, folders, volumes, and virtual hard disks (VHDs) from a host-level backup of Hyper-V virtual machines to a network share or a volume on a DPM protected server. You must have the Hyper-V role enabled on the DPM server to perform item-level recoveries. During item-level recovery, DPM has to mount the VHDs of the protected virtual machines
- Install DPM server pre-requisites
- Install DPM 2010
- Turn off “TCP Chimney offload”For better throughput, TCP Chimney Offload should be turned off.
- Allocate Storage Pool & Deploy Agents
- Datasourcegroups.xml file:
- Merge the DatasourceGroups.XML file for all CSVs protected by DPM server. This is applicable when software providers are used on the CSV cluster.
- Copy the <Group> tags from all the DataSourceGroup.xml files generated and add the text between the <DataSourceGroup> tags. The DataSourceGroups.xml file will now contain one <header> tag, one <DataSourceGroup> tag, and <Group> tags from all CSV clusters.
- Configure Protection Groups
- DPM2010 provides Datasource caching for faster enquiry.
- Remember to clear cache if new VMs have been added
- Enable AutoProtection:
