Step 4. Enabling Linux Restore
At the Subscription step of the wizard, specify whether you plan to restore Linux-based machines. If you are planning to restore them, select the Enable restore of Linux-based computers check box.
Veeam Backup & Replication will deploy a helper appliance in Microsoft Azure and use it for restore of Linux machines. For more information about helper appliances and how to setup up them, see Configuring Helper Appliances.
