Summary
This article describes an important update to Azure Backup for Microsoft Azure Recovery Services (MARS) Agent version to 2.0.9173.0, that is used both by Microsoft Azure Backup and the Microsoft Azure Site Recovery service to transport data to Azure.
New Features
Support for Data Box Disk and Data Box Pod for sending initial backup data to Azure
With this release we have added support for Data Box Disk and Data Box Pod as optional means to send backup data offline to Azure. This feature, currently in public preview, is particularly useful for scenarios where the volume of data or network bandwidth availability or both makes the offline transfer more advantageous. With the use of Data Box Disk and Data Box Pod, users can avoid the need to provision additional local storage, network and burden of procuring compatible disks and connectors. Review this feature announcement article for more details.
Important Improvements
Deprecation of Windows Server 2008 and Windows Server 2008 R2
With the end of support of the Windows Server 2008 and Windows Server 2008 R2 Operating Systems (OS), their use with MARS Agent is on the deprecation path. In this release, we have added additional messaging for user awareness so they can schedule OS upgrades at the earliest. If you cannot update the operating system due to existing commitments to this version, please review the deprecation announcement for alternatives and more details.

The passphrase set and change experience has been improved with additional messaging to emphasize the importance of storing the passphrase in a secure remote location.
