Backup fortigate Firewall VM with Azure Backup (Solution)

The documentation is simple and it is based on screenshots (step by step)

Unfortunately, Azure Backup does not allow backup of a Fortigate VM (or most appliances in the Azure Marketplace).
Only Azure approved distributions are supported: https://learn.microsoft.com/en-us/azure/backup/backup-support-matrix

Example of the error obtained when you launch the backup of a fortigate VM?

{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.","details":[{"code":"Conflict","message":"{\r\n \"status\": \"Failed\",\r\n \"error\": {\r\n \"code\": \"ResourceDeploymentFailure\",\r\n \"message\": \"The resource operation completed with terminal provisioning state 'Failed'.\",\r\n \"details\": [\r\n {\r\n \"code\": \"UserErrorUnSupportedDistribution\",\r\n \"message\": \"Unsupported OS version for virtual machine backup.\"\r\n }\r\n ]\r\n }\r\n}"}]}

---> The agent cannot install correctly in the Fortigate VM

A solution ?

----> through snapshots in Azure Backup.

We can make a small LAB that already contains the configured Fortigate VM.

1- Create a Recovery Service Vault

Go to  'RSV'  --->  Backup Center 

Then, Click on VAULT

You must choose, Backup Vault 

you have to choose the necessary parameters : 

The next step is to create the Policy, 

You muste choose the Datasource type : Azure Disks and the right Vault type also. 

Here, you configure the policy as you need. (Choose the right parameters)

Here, you choose the configuration according to your need.

2- Now we need to add the necessary permissions

- Permission on the disks of the VM fortigate

Go to the disks of the VM fortigate and follow the screenshots : 

Click “Add role assignment”, then “disk backup reader” role.

Give the role to the Vault.
