Security and Performance
General
The Veeam Plug-In for Microsoft Azure appliance and its worker VMs can now be deployed with Encryption at Host enabled. This feature requires Veeam Plug-In for Microsoft Azure build 13.8.4.19 or later, and the target Azure region and subscription must have Encryption at Host enabled.
To enable Encryption at Host:
On the Veeam Backup & Replication server, add the following line to C:\ProgramData\Veeam\Backup\Plugins\Microsoft Azure\Config.xml:
<ServerDeployOptions EncryptionAtHost = "true" />
All subsequent Veeam Plug-In for Microsoft Azure appliance deployments will then be launched with Encryption at Host.
After the appliance is deployed, connect to it over SSH and add the following lines to /etc/veeam/azurebackup/Config.ini:
[WorkerVmDeploymentOptions] EncryptionAtHost = "true"
All worker VMs deployed by the appliance will then use Encryption at Host.
Update the appliances as described in the Upgrading Backup Appliances section of the Veeam Plug-In for Microsoft Azure User Guide.
Alternatively, follow the instructions in the Installing Updates section of the Veeam Plug-In for Microsoft Azure User Guide.
