Azure Backup has announced a new pricing model for data being backed-up to Azure. This new model is based on the number of machines that are being backed-up, and is measured and reported in the monthly Azure bill as Protected Instances . The new pricing has an impact on the Azure Backup bill for the data sources being backed-up to Azure via DPM servers, and this blog provides an overview of the changes that DPM customers should expect.
To begin with, you can read more about the new Azure Backup pricing and have a look at the FAQs on the pricing page .
In deployments where DPM is protecting your data sources, the primary site machines are the Protected Instances being counted for billing. The notion is simple – Azure Backup is charged based on the machines being protected to Azure, and DPM is just the conduit for the data flow. Thus in the sample deployment below, the servers marked in blue will be counted towards the Protected Instance usage and the DPM server (in grey) and the local data is not counted for the purposes of billing.
In this example, the monthly software management cost is calculated and shown in the table below:
S. No. | Machine type | Size of machine | Size bucket | Monthly cost | |
1 | File Server | Physical host | 600 GB | between 500GB and 1000GB | $20 |
2 | SQL Server | Physical host | 75 GB | between 50GB and 500GB | $10 |
3 | Virtual machine | VM | 30 GB | less than 50GB | $5 |
4 | Virtual machine | VM | 150 GB | between 50GB and 500GB | $10 |
TOTAL: $45 |
Note that Hyper-V hosts are not counted for the Protected Instances calculation. Instead, the Hyper-V virtual machines are used for the calculation. You can find more information on the datasources supported with DPM in the Pricing FAQ , along with more examples.
A DPM deployment could be a few tens of machines or could scale to a few hundred machines. In order to estimate the number of Protected Instances and the storage utilization, follow 2 easy steps:
The totals row in the HTML output contains the following information:
That’s it! The excel sheet will give you an estimate for the first month’s bill with Azure Backup. Note that this estimate does not include the savings in the storage bill due to compression – so your actual bill could be even lower. With long term retention policies the amount of data stored could increase, and this needs to be factored in for estimates involving future months.
Starting April, most customers would automatically be on the new pricing model. However there are certain customers with Enterprise Agreements or Volume Licensing agreements that will continue on the per-GB model. These customers can view their current pricing model and change it from the Azure portal.
