I am an inflated reader of articles about DR and BC. I am currently working about the further perspective to build a second data center with DR&BC features and in the first phase together with all team try to figure out how should we draw up a tender specification document. This latter will address our high demands to develop and implement in mirroring to the secondary site (localized to a distance about 200 km ) only our production environment using an Active-Active topology in synchronous mode with RTO 4 hours and RPO 0 (ZERO DATA LOSS).
Considering the above mentioned kindly ask to share with me some thoughts or other suggestions to be taken into consideration in the writing of tender specifications in order to attain and fulfill the mission and the scope of our critical project.
Thanks in advance for all your commitment and the valuable support on this matter.
