I have a RTO of 30 minutes. data rate of change is aprox. 50 GB per day how much bandwidth should I buy?

kuku,
It would be best to contact your service provider (EMC business partner or EMC technical coordinator) and they can work with you directly. They will (may in the case of EMC business partner) have access to a tool called Business Continuity Solution Designer (BCSD) which was intended to be used to assist with the analysis/sizing/design of remote replication solutions such as SRDF and determining the resource requirements (network throughput, number of RAs, SRDF/A cache, etc).
Ask for it by name when you talk to them and see if they can make some suggestions that you can commit to.
