Veeam 11 Windows 10 Hyper-V backup question

I have to replace a SCSI tape drive with SAS to upgrade to Veeam 12.   I have to replace the OS on the Veeam server to upgrade to 13.

I am still on Veeam 11.  I have HP Z840 workstation that is on Windows 10 Hyper-V.   I am moving VMs from VMWare 6 to this workstation.   I have so far installed our children’s minecraft servers on Ubuntu 24.04 as virtual machines.    I setup for file level backups.   I want to backup each VM in E:\Hyper-V separately.   Each VM has its own folder and VM structure in this directory.   E:\VMBackups has a script that removes and replaces each of these VMs.

# Import the Hyper-V module
Import-Module Hyper-V

# Define parameters
$BackupDriveLetter = "E"  # Change to your backup drive
$VMHost = "localhost"      # Change if backing up from a different host
$VMNames = @("Bedrock2404_10.10.10.3", "Bedrock2404_10.10.10.4", "Bedrock2404_10.10.10.5", "Java2404_10.10.10.6", 
             "Java2404_10.10.10.7", "PaperMC_10.10.10.8"  ) # List of VMs to back up

Remove-Item -Path E:\VMBackups -Recurse -Force

# Function to back up VMs
function Backup-VMs {
    param (
        [string]$BackupDriveLetter,
        [string]$VMHost,
        [string[]]$VMNames
    )

    foreach ($VMName in $VMNames) {
        # Export the VM
        Export-VM -Name $VMName -Path "E:\VMBackups\$VMName"
    }
}

# Call the backup function
Backup-VMs -BackupDriveLetter E -VMHost $VMHost -VMNames $VMNames

How do I setup a file level backup to recover each directory separately in case of issues on their minecraft servers.   

How do I recover at the folder level?   Do I need to upgrade to v12 or v13 to do this?
