Backup Extreme Summit switches using TFTP commands

Hi, We have just installed some extreme switches and currently
it is backing up using model X450-24X running the show configuration command.

We are wanting to run the following below command and wondered whether this
would be possible if we had a variations file and running a TFTP server on
server where cat tools is installed.

tftp put x.x.x.x vr "VR-Default"primary.cfg **Saved file name***.cfg

The above command makes it easier to restore configs if we were to have issues.

We tried running Device.Backup.TFTP activity but it currently only supports Cisco Devices.

Thanks
