I am looking for software to replicate files and web content from one server to another. We have a 3 server farm and people can be attached to any of the servers uploading content and/or files. Currently my replication is going from A -> B and A -> C (synchronized both ways) which works great as long as A does not go down. We publish to A only, and customers upload to A, B, or C, depending on what server they get attached to. I need to be able to publish to any of the servers and to copy files from server to server regardless of whether "A" is available. What software products are others using? Opinions are appreciated. thanks
