Our company would like to do a project on remote disaster recovery, currently we have our SAP ERP system in Coutry A, we would like to setup an additional site on another country - Country B, could you kindly share your experience on how to do it? by software or by hardware?
The purpose is: normally, the system in Country A provide services for all users, and the system in Country B timely synchronize data with the system in Country A, once the system in Country A crashes, system in Country B should take the responsibility in no more than five minutes, then we will have enough time for repairing system in Country A, once it is back to normal, system in Country A will synchronize data with system in Country B (all delta data happened during the downtime should be copied back)
If you have such kind of experience, please kindly give me some idea/guides.
Thanks a lot!
