This article describes new features, improvements, and fixes that apply to Azure Backup for Microsoft Azure Recovery Services (MARS) Agent version 2.0.9070.0 that is used by both Microsoft Azure Backup and Microsoft Azure Site Recovery (ASR) to transfer data to Azure.
Instant Restore speed and reliability improvements
We introduced Instant Restore in the January 2017 update for the MARS Agent. In this update, users of Instant Restore experience significantly improved speeds at which files and folders can be recovered by copying to a local computer from the mounted recovery volume.
Several reliability improvements have also been made to provide more robust item-level restore operations of large data sources.
Integrity Check Improvements
In this update, users experience more robust integrity checks because of improvements that are made in checksum comparisons.
The Microsoft Recovery Services Agent cannot connect to the OBEngine service. Verify that the OBEngine service is present in the Services Control Panel and that port 6049 is available.
Please close the Microsoft Azure Backup snap-in and restart it.
