User manager Back up options

Hi Guys,
I have been using UM now for about 3 years. I have not really had much time to play with it any further, other than to add new clients to it every day :slight_smile:
It seems very basic to me for what it can do and I feel there should be more options with it.

But my biggest concern at the moment is it crashing on us. Its the only radius server we have for our entire network.

Does anyone have installations that where you have 2 user managers running simultaneously, one the master and one the slave lets say. Is it possible to have the master update the slave with its records once a day just incase our master falls over and we need the slave to take over? Or a similar example.
