There are a set of servers that will need to be replicated to another site. The secondary site will house an exact replica of the data that is in the original servers. The software that we will be using in order to replicate the servers is a mixture of DoubleTake, DFS and vRanger. In order for the replication to occur over the Internet we need to provision an Internet connection that is big enough to sustain all of the changes that occur after the initial seeding of the data. We dont want to provision an Internet connection with too much bandwidth because we will be paying too much and we dont want to provision a pipe that is too small. The Internet connection will need to be purchased before the hardware and software are purchased due to construction times.
A piece of software or tool or method that will report the bit-level changes on a day-to-day basis prior to the hardware and software being purchased is the preferred way of provisioning the Internet connection. This will give us a very specific metric for the Internet connection. Does anyone know of a way to determine the bit level changes to all of the files on a set of Windows server running various applications such as Exchange, SQL, BES and file-print?
