What will be the best way to have Disaster Recovery of site ( File & Print and Messaging Soluton. ). at remote location with approx. 300 km. distance.
One thing you should consider is whether you really want DR for File & Print and Messaging servers. These functions are easily reproducible with proper backup/restore procedures. DR (both hot and cold DR sites) is an expensive proposition. Keep it only for critical business processes e.g. your ERP & CRM systems or your Software Development systems.
