Backup Exec 16 FP1 introduces the Enhanced Resiliency feature for the instantly recovered virtual machines to improve business continuity.
What can I achieve using this feature?
In the earlier release, the Instant Recovery feature had a limitation. The instantly recovered virtual machines were unavailable if the Backup Exec and/or the Hyper-V servers restarted.
The Enhanced Resiliency for Instant Recovery increases the data and application availability of virtual machines that are instantly recovered. This improves business continuity in case the Backup Exec server or the Hyper-V server must be restarted. As soon as the restart is complete or network connectivity is restored, virtual machines restored with the "Instant Recovery" feature come online automatically.
Use case 1: Hypervisor reboot
Use case 2: Backup Exec server reboot
Use case 3: Network disruption
Use case 4: Unexpected shutdown
Do I need to purchase an additional Backup Exec license to use this new feature?
No additional license is required.
What are the additional system requirements for using this feature?
There are no new system requirements for this feature.
How does this feature work?
The ‘VxLatServer’ process is primarily responsible for keeping the instantly recovered virtual machine in a functional state.
If this process is not running, the instantly recovered virtual machine stops working.
The enhanced resiliency for instantly recovered virtual machines introduced in this release ensures that this process is launched again after the Backup Exec server and/or the Hyper-V server restarts.
When the ‘VxLatServer’ process is launched for the first time, some metadata is collected and saved in a repository. The metadata is used when the process needs to be launched again.

Are there any performance impacts due to this new feature?
