Managing Helper Appliances

To restore Linux workloads to Microsoft Azure, Veeam Backup & Replication requires helper appliances. During the restore process, Veeam Backup & Replication mounts disks of the restored workload to the helper appliance to prepare these disks for restore.

A helper appliance is a small auxiliary virtual machine that Veeam Backup & Replication automatically deploys in Microsoft Azure. When deploying the helper appliance, Veeam Backup & Replication analyzes the VM sizes available in the restore region and selects the cheapest and smallest size suitable for using the helper appliance.

Helper appliances are persistent. After the restore process finishes, helper appliances get powered off and remain in Microsoft Azure. The appliances remain in the powered off state until you start a new restore process. Note that Microsoft Azure will bill you for storing helper appliances disks in the storage account. To remove a helper appliance, follow the instruction provided in Removing Helper Appliances.
