Vol. 17, #49 - December 3, 2012 - Issue #908
This week's issue of WServerNews is about cloud backup. But before we dig into this topic, let's first find out what sort of advice an expert consultant like Dogbert might give to an organization that's thinking of migrating their business processes into the cloud:
By the time you're reading this newsletter my latest book Training Guide: Installing and Configuring Windows Server 2012 should be available:
You can order it here from Amazon:
For an excerpt from one of the chapters in this book, see the Tech Briefing section of this newsletter.
This is (I think) my 30th book about Microsoft products. That sounds like a lot, but my colleague and fellow author William Stanek has just finished his 150th book:
That's disgustingly prolific, isn't it?
And now for the mailbag...
In the issue Hyper-V Backup and Restore (Issue 905) we described some tools for backing up and restoring Hyper-V hosts and their virtual machines. A reader named Felix from Australia had another product to recommend:
I use BackupAssist from Cortex I.T. Labs, which supports (among other types of backups) Hyper-V backups. It uses the inbuilt wbadmin tool but does it in a very user friendly way and provides a comprehensive backup report. There is an optional Hyper-V recovery option that mounts the backup image of a VM as a drive letter for easy restore. They also have options to backup Exchange mailboxes and, file backups to other servers on the network and in the cloud. Very reasonably priced!
Another reader named Bill, a Senior Systems Administrator in Ohio, shared about the problems he has been having with his current backup solution:
Symantec Backup Exec 2012 is a nightmare. It has been since we upgraded from 2010 R3. In fact I rebuilt the server from scratch and it did no good. 2012 originally had some serious issues working with MS VSS. That took several weeks to look into. After some hotfixes and SPs it will not do any sort of granular backup of SQL and Exchange VMs. We can only get granular backups of simple file server and IIS type VMs.
There's been an open case with Symantec for over a month. After sending them extensive debug logging info they're chalking it off to a persistent issue that is currently under investigation. As a result I'm now looking at Veeam for our HyperV environment.
Our issue Cloudy Thinking: PaaS (Issue 906) briefly discussed the Platform as a Service cloud computing service model and described a number of different popular PaaS service providers. One reader thought our discussion of PaaS was too brief and missed some important points:
Longtime subscriber to WServer News, but this is my first email. I write this because I think you were off base on a number of your comments about PaaS.
First of all, you write as if PaaS is a deployment only model. Although that might be true for many or most of the offerings you mention, it is certainly not universal. Both the Oracle Database Cloud and Salesforce Force.com allow for development and deployment in their PaaS offerings, which is not just a detail. With these services, you dramatically change your development methodology, allowing for iterative development where changes take effect immediately.
Secondly, you have a small point on your discussion of the proprietary nature of PaaS, but you miss the big point. The core issue is that moving to a shared environment (by definition, PaaS environments are shared, to some extent -see the next point) means a firmer lockdown of resources. This means that any app you developed outside of a PaaS environment will probably have some calls, etc., which are not supported on a target PaaS. Although it is true that, right now, most PaaS have slightly different restricted lists, there is less difference between PaaSs than between out of the Cloud and in the Cloud. So there will always be migration costs. Heck, there are migration costs (testing, etc.) when you move to a different in-house operating system - and these costs are not trivial. The bottom line here is that, by and large, migration is typically a bad use case for the Cloud. A much better idea is to say that new development will live on the Cloud and, once this goes on for a while, migration might be considered, along with recreation of the target app.
Thirdly, you say that you are locked into a Cloud PaaS vendor, and if they go away, you are toast. Not at all true with the Oracle Database Cloud - you can move everything in the Service, data and apps, to any environment that supports the Oracle stack.
Finally, you don't even touch on the other key difference between PaaS/SaaS and IaaS - multi-tenancy. Many PaaS providers do not really give multi-tenancy, instead using VMs. (No, I do not think that VMs are mufti-tenant - they are not nearly as scalable and require additional management, unlike a true multi-tenant environment) This difference will, moving forward, become a bigger and bigger differentiator.
The reader makes some good points here. For example, I should have explicitly mentioned the development aspect of deploying PaaS solutions as something you should investigate before you buy into a vendor's PaaS offering. I still feel however that lock-in can pose a problem with some PaaS hosters, and if you plan on developing custom applications on a PaaS hosting provider's cloud you better be sure that your code is portable to several other PaaS hosting providers should the one you're working with go under. As for multi-tenancy, I'll probably visit that topic in a future issue as it's another important consideration when implementing any kind of cloud computing solution.

We've visited the topic of backup several times recently, and we'll probably continue to do so from time to time because business continuity is important for all businesses, large and small. While tape backup is still used by many companies for archival purposes and disk-to-disk backup is increasingly popular, there's increasing pressure in the marketplace for businesses to consider cloud-based backup as an alternative to implementing an in-house backup system.
Benefits of cloud backup
The potential benefits of cloud backup are similar to those of other types of cloud-based services. These benefits can include:
Risks of cloud backup
Like other forms of cloud computing however, cloud-based backup can also pose certain risks:
Bottom line for businesses
Like everything else in IT, it all comes down to weighing the benefits against the risks before you make your decision.
Windows Azure Online Backup
Windows Server 2012 now includes an optional in-box cloud backup solution called Windows Azure Online Backup. By using this feature, you can back up volumes, folders or files on your servers to cloud storage hosted by Microsoft. Windows Azure Online Backup is built into the Windows Server Backup utility, but before you can use it you need to first create a user ID on the Windows Azure Online Backup website. This user ID will of the form username@NAME.onmicrosoft.com where NAME is a name you choose to represent your organization within the Microsoft Online Services cloud.
Once you've done this, you download a Windows Azure Online Backup Agent from the website and install it on your server. At that point, an Online Backup node will appear in the Windows Server Backup console like this:
Once you've created your user ID, you click Register Server and specify a password used to encrypt your backed up data. You are then ready to schedule online backups, recover data, and perform other operations as shown here:
There's also a free preview of Windows Azure Online Backup that gives you 300 GB of cloud storage. I encourage you to download Windows Server 2012 today and try out Windows Azure Online Backup and let me know what you think of it by emailing me at email@example.com.
