What software can I use to mirror data (files/folders) between two Windows servers across a broadband internet connection?
I'd like to implement an off-site backup solution for a company with two locations. Instead of transporting external drives to/from the locations or employee homes, I am interested in implementing a data mirroring solution that will use two servers to back each other up. The idea is that in the event of a physical catastrophe, one server should have the data for both locations.
Both servers will be running Windows Server 2008 or newer and both will have disks arranged in a RAID for local redundancy and drive failure protection.
I had encountered a software program at one time that was designed to accomplish this mirroring by limiting the bandwidth used on an internet connection during business hours, and doing the majority of data mirroring at night. The idea being that data is copied to the other server as soon as it is changed, but in such a way that bandwidth usage does not compromise business activities. Unfortunately I cannot remember nor find such a software program and am looking for advice from the ServerFault community.
