Re: Choosing The best replication system.
Thanks for the information below, just couple of questions need to clarify. If we say Point A is the Master Server, Point B and Point C are Slaves, does All Authorisation as in prepaid and account info which are stored on the Master will they replicate in real time to Point B C? Also if Point B uploads the accounting info at the end of the working day to the master Server will Mysql replicate down to point C?

Re: Choosing The best replication system.
Anyone out there with some guide or atleast some pitfalls i should try and avoid on Replicating the radius server ?
