I need a program that will keep two loadbalanced servers in sync. I've been looking at replication packages like this http://www.veritas.com/products/category/ProductDetail.jhtml?ProductId=storagereplicatornt but it seems to be 'one way' replication, not true syncronisation. Each server needs to be a source AND a target....get me? So, my question is, has anyone here done this before? What software? Can each server be a source and a target?
