We have a new file server to handle the obscene amount of files generated by the company (PDFs, XLS, DOCs and JPGs). Files being moved to the new server total about 3tb. The problem is we can't take the company down for days to move the files. The other problem is the applications creating all these files have to reference previous files, so we can't simply point them to the new server. Also, there isn't an option to have the applications create files on the new server, but reference the old server for existing files.
The servers are x64 win2003 r2. Both servers are on the same subnet.
DFS doesn't work.
Is there an application that can handle this amount of data to copy the files over, throttle bandwidth, and do a 'merge'? By merge I mean constantly copying over newly created files until the two servers are synched.
