Hello @Rahul Gupta Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
From the details shared in the original post, I understand that you are trying to enable backup on FortiGate VM and being greeted with an error message.
Unfortunately, Azure Backup does not support backup of Network appliances like Fortinet FortiGate or most appliances in the Azure Marketplace) for a VM backup. For Azure VM Linux backups, only Microsoft Azure approved distributions are supported - Linux distributions endorsed by Azure. Reference: https://learn.microsoft.com/en-us/azure/backup/backup-support-matrix-iaas#operating-system-support-linux https://learn.microsoft.com/en-us/azure/virtual-machines/linux/endorsed-distros Other bring-your-own Linux distributions might work as long as the Azure VM agent for Linux is available on the VM, and as long as Python is supported.
As a workaround, you can use a snapshot as a point-in-time backup, or to help troubleshoot virtual machine (VM) issues. You can take a snapshot of both operating system (OS) or data disk VHDs.
