complete vm backup(along with disks)

Hello Team,

We have a VM which hosts SQL Server. Now we have moved the database from this VM to SQL Server service.

Now we would like to take a back up of the VM and all its associated disks and archive to cheap storage before deleting the VM and the associated disks.

Please provide guidance on how to take back up of the VM and its associated disks and also on storing the backups (to save cost).

Thanks,
