primary backup configuration

[Maqbool Hashim]

Hi,

I have two radius servers one primary and one backup one, on different 
ip addresses.  They both have a mysql backend which runs on the same 
physical machine.  I need the sql database and radius configuration 
files to be synchronised periodically (probably every 24hours).  I guess 
this is a common setup, so I'd appreciate some ideas as to the best way 
to achieve this?

Thanks
