Microsoft has corrected and changed the description of the new pricing for Azure Online Backup that comes into effect on April 1st. This is after the owners of the website royally screwed the pooch in February with a confusing and incorrect posting.
NOTE: I am redacting this post because no one is able to explain what a “protected instance” is. Until then, while Azure Backup is great technically, and could be cheap, I have no idea how much it will cost.
As with all posts regarding licensing or pricing on this site, I will not be answering questions. Ask your reseller, distributor or LSP – they’re the people you are paying so they are the people who can do the work.
With the new pricing you no longer pay (using North Europe pricing in Euros) €0.149 per GB stored in Azure per month. Instead the pricing is broken into 2 pieces:
Instances
Think of an instance as The block of data that has to be protected. I
The charge per instance depends on the size of the instance. Sigh! This charge is based on the size of the protected instance. I do not know if this is based on data protected or the total amount of disk space in the instance. Another sigh!
Less than 50 GB:€3.7235 per instance
50 GB to 500 GB: €7.447 per instance
Larger than 500 GB: Multiples of the 50-500 GB charge
Storage
Azure Online Backup will use Block Blob Storage. You can use either LRS (3 copies in 1 data center) or GRS (3 copies in 1 data center, and 3 async copies in another region) at a higher cost.

Examples
The end result is that for most customers, the pricing will come way down.
1 File Server with 30 GB on LRS Storage
1 instance: €3.7235
Storage: 30 GB * €0.0179 (LRS) = €0.54
Total = €4.26
4 Machines with 80 GB each on LRS Storage
4 instances: €7.447 * 4 = €29.788
Storage: 30 GB * 4 * €0.0179 (LRS) = €5.73
Total = €35.52
1 Machine with 1400 GB on GRS Storage
3 instances (3 * 50-500 GB): €7.447 * 3 = €22.341
Storage: 1400 GB * €0.0358 (GRS) = €50.12
Total = €97.52
Wrap-Up
As I have told some people in Redmond, the added complexity to Azure Online Backup pricing is indicative of everything that is wrong with Azure pricing. The only blocker I’m seeing in Azure sales is that sales people cannot get their heads around the wildly varied and complicated pricing. I really don’t care what AWS does – I don’t work with AWS and what they do to limit their own sales is their issue. Microsoft needs to fix the pricing structure of Azure to grow it the way they want, and need, to.
