A mixed bag of FAQs about data copy and backup in Azure plus will we ever see another Service Pack?

Q. If I perform a server-side asynchronous copy of data between Azure regions is it done via the Internet or does it stay on the Azure backbone?
Dept - Azure

A. When using the server-side asynchronous copy, the data copy is performed storage account to storage account via Azure rather than the data copying via the client requesting the copy. This account-to-account copy method avoids huge latency, as the data would have to be read by the client then sent back to Azure. If you perform a copy between Azure regions that data copy will stay on the Azure backbone and will not traverse via the Internet.

Q. What is the largest data source size I can backup to Azure Backup vaults?
Dept - Azure

A. The Azure Backup vaults themselves have no practical limit however the source of data has a size limit. These are documented at and are basically:

  • 54.4 TB Windows Server 2012/Windows 8 and above
  • 1.7 TB Windows Server 2008 R2/Windows 7 and older

Q. Will there be Service Packs for Windows Server 2016/Windows 10?
Dept - Service Packs

A. No. Microsoft have moved to a monthly Cumulative Update (quality update). Additionally there is the 6-monthly Semi-Annual Channel that delivers new functionality (or customers can use the Long-Term Servicing Channel for the standard 5 year + 5 year extended support). There are no plans for Service Packs going forwards.
