We have a GW2012 postoffice running on Win2008r2 that is currently about 1.5TB large and slowly growing. It's running very well except when we do our DR exercise and have to rebuild it. It was suggested by our storage vendor to break up the post office into separate volumes (e.g. put the offiles and ofusers folders on a separate volumes) which would allow the server to be restored faster. Not sure we want to do that just for the DR recovery, but is that even possible?
