File Transfer Between 2 RB Units

I have a situation where I would like to transfer a file between (2) RB133 units. I want to use the scheduler to automatically transfer a file at a preset time on a daily basis from one unit to the other. The 2 RB units are on the same subnet are directly connected via ether2 on each unit.

I realize I could automate FTP or Telenet from external equipment but would like to just use the RB units to complete the task if possible.

Does anyone have suggestions how to perform this process with just the 2 RB units.

Thank You.

Does anybody have any ideas?
