Hi Rajvs,
Certainly the least expensive option would be an internet site to site VPN over whatever Internet access is available. However, that Internet traffic may just be riding the same network backbone as your MPLS connection and, in the event calamities, it may also go down.
Certainly the more expensive but most reliable option for DR would be VSAT. In other words, with VSAT you are going over a complely seperate network.
As long as you are okay with the satellite latency and the price is acceptable, i would go with the VSAT solution because it is a diverse path.
Hope that helps!

Network, Vsat, MPLS
Presently, I am using an MPLS link to connect our operation between indonesia and india. Would like to introduce a redundant line inorder to help us keep up the connectivitiy during times of natural calamities (like flood, quake etc.,) What would be best option for this link? Would Vsat be a wiser choice?
