Security and Performance
General
The Veeam Backup 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 Backup 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 Backup for Microsoft Azure User Guide.
Alternatively, follow the instructions in the Installing Updates section of the Veeam Backup for Microsoft Azure User Guide.
