If you have a small number of servers to protect and you currently have no backup solution, you are using the in box Windows Server backup tool on these servers, or use a third party backup solution, Windows Azure Back may be a viable option for you. If you have a larger infrastructure and already using System Center 2012 and using DPM for protection and you want to keep replicas offsite, Windows Azure backup is a brilliant solution. In this post we will look at both of these scenarios and give you the information you need to get started, including a Step-by-Step on how to deploy, configure and manage Windows Azure Backup on Windows Server 2012 R2. This post is part of the Windows Server 2012 R2 Launch Series.

The amount of data organizations are collecting and now storing is rising. Analysis tells us that data rates are growing at over 40% per year. 90% of the world’s current data was created in the past 2 years. This rapid rise means that the cost of storing this data is rising year on year. The good news is the cost per terabyte is falling year on year, but unfortunately not at the same rate as data growth. The cost of backup is also rising, from purchasing a solution, running it, and training people to use it. The cost and complexity of managing the storage is a factor – you have to manage all the backup media, store it, and test it in case you need it. All this leads to the possibility that important data may go unprotected, either entirely or for longer periods than is ideal. As we consider these challenges, let’s see how Windows Azure Backup helps address them.
What is Windows Azure Backup?
Windows Azure Backup helps protect server data against loss and corruption by enabling backup to offsite cloud storage in Windows Azure. It provides a consistent experience configuring, monitoring, and recovering backups across local disk and cloud storage, integrating with the in-box backup program in Microsoft Windows Server or System Center Data Protection Manager. Windows Azure Backup encrypts and protects your backups in offsite cloud storage with Windows Azure, adding a layer of protection in case data loss or disaster impacts your servers. It can integrate with the backup tools in Windows Server or System Center Data Protection Manager as well as being driven by PowerShell scripting. You can manage cloud backups from these familiar tools to configure, monitor, and recover backups across local disk and cloud storage with ease. Windows Azure Backup delivers efficient data protection. It minimizes network bandwidth use, provides flexible data retention policies, and provides a cost-effective data protection solution that can be Geo replicated with ease. Data stored in Windows Azure is geo-replicated among Windows Azure data centers, for additional protection. Your data is encrypted before it leaves your premises, and remains encrypted in Windows Azure – only you have the key. Incremental backups provide multiple versions of data for point-in-time recovery. Plus, you can recover just what you need with file-level recovery.
What Does Windows Azure Cost?
We charge for backup based on the amount of data stored in the Backup service. We do not charge additionally for bandwidth, storage, storage transactions, compute, or other resources associated with providing the Backup service. Windows Azure Backup was made generally available on October 10, 2013. Promotional preview pricing remains in effect until November 30, 2013. If you have less than 5gb of data to backup per month it is absolutely FREE. I really like free but that is not the good news. The good news is the cost when using it at scale in production. On Dec 1st the price will change to $.50 cents per GB per month. Yep, that’s right you can backup your server for the month for about the cost of a cup of coffee. See Chart Below… Keep up with the most recent pricing and review the 6 or 12-Month Plan options for even more savings at http://www.windowsazure.com/en-us/pricing/details/backup/
|COMPRESSED DATA STORED PER MONTH||PRICE
(starting Dec 1)
(until Nov 30)
|First 5 GB / Month 1||Free||Free|
|Greater than 5 GB / Month||$0.50 per GB per month||$0.25 per GB per month|
1 For monetary credit offers, backup will be charged at the billable tier.
The amount of storage for which you are billed is determined by the compression ratio and the number of backups retained. The charge for backup storage is prorated daily. For example, if you consistently utilized 20 GB of storage for the first half of the month and none for the second half of the month, your average daily amount of compressed data stored would be 10GB for that month. Since the first 5GB each month is included at no charge, your bill for that month would be $2.50 (5GB x $0.50) for that month (Way less than a cup of coffee).
What is Geographic Availability?
First let me say, from a backup perspective, I would recommend that you use a different data center for your backup than your physical location. If you are backing up on-premise machines and you are on the east coast set your backup storage to be on the west coast. If you are backing up Windows Azure machines that are configured for East, back them up in west.
Backup is available in the following regions:
|United States||US West, US East|
|Europe||Europe West, Europe North|
|Asia Pacific||Asia Pacific East, Asia Pacific Southeast|
When can/should you use Windows Azure Backup?
If you’re already using System Center Data Protection Manager, you can start using Windows Azure Backup today – it integrates with System Center Data Protection Manager. If you’re a small business or branch office and have a small number of servers to protect, Windows Azure Backup integrates with the in-box Windows Server backup tools you may already be using. Windows Azure Backup is suitable for any workload, file servers, SharePoint®, SQL, Exchange, or others. Windows Azure Backup integrates with Windows Server technologies to make this happen.
Small Business or Branch Office
if you have a small number of servers and you want to protect the data they hold using the tools built-in to Windows Server 2012 R2, the process to configure Windows Azure Backup is relatively simple. First, sign up for a Windows Azure account. This will provide you access to the Windows Azure Management Portal. From there, you can select the Recovery services option and add the Windows Azure Backup service to your account. The next step involves an exchange of data. We’ll cover the certificate part later on in the security section, but for now the important part is the installation of the agent on the server or servers that you want to register to use the Windows Azure Backup service. As mentioned, the Windows Azure Backup agent integrates with the existing Windows Server backup tool. When you start the tool after the agent installation, you register this server using your certificate. The certificate can be self-signed or public. Then you configure what data you want to back up and what schedule you want to use. That is it. If you are using a schedule, the server will now back up your data to that schedule. You can monitor it from the backup tool, to see when the backup ran, when the next one will run, and view any issues. If you need to recover data at any time, for example a server failure, or even an accidental deletion of a file or folder from a location being protected, you can use the backup tool to recover that data. Windows Azure Backup provides very granular recovery options, either to the original server or a different one. Recovering data to an alternative server is a good practice for testing recovery procedures. If you don’t have a physical server to restore to, create one on Windows Azure .
Enterprises with System Center
Let’s now look at how Windows Azure Backup works in an environment where you are using System Center Data Protection Manager. Most of this procedure is the same as we’ve just seen.
First, sign up for a Windows Azure account as we talked about above. The next step involves installing the agent on the DPM server, not, as in the previous example onto the server you want to protect. The Windows Azure Backup agent integrates with DPM. When you restart DPM after the tool has been installed, you register this server using your certificate. Then you configure what data you want to back up and what schedule you want to use. The DPM server will continue to protect the existing server as it did before the agent was installed, but the server will now back up data from servers you have configured. If you need to recover data at any time, for example a server failure, or even an accidental deletion of a file or folder from a location being protected, you can use DPM to recover that data, while still continuing to monitor and protect the other servers.
Is Your Data Secure?
The first stage in the transfer process is the encryption of your data on premise using your key. Your data stays encrypted with your key while in transit over the wire to Windows Azure storage. Your data stays encrypted while in Windows Azure storage. It is never decrypted while it resides in Windows Azure storage. Your data can only be decrypted once it’s restored on your premises. Only you have the decryption key to do this. This makes it very important to protect this key. Make sure you back up your key, keep it safe, and store a copy offsite. Your data cannot be decrypted without it. In the event of key loss, Microsoft cannot help you as Microsoft does not keep a copy of your key and has no access to it. The key is never passed to Windows Azure during any Windows Azure backup. If you need at some point to change the key, it is easy to do. Simply create a new key upload it to Windows Azure and tell Windows Azure Backup to use the new key.
How is Windows Azure Backup Deployed?
Windows Azure Backup is deployed by configuring or enabling the services on Windows Azure then installing an agent on the server that communicates with the service.In this Step-By-Step post we will go through the entire process Step By Step so you can easily deploy in your environment.
