I'm running into the issue that Unity Connection will not backup using freeFTPd as the backup server with files over 1 GB (my mailstore is just over at 1.2 GB). I've tried setting up one of the recommended servers, Openssh and cygwin, but my problem is that I can't find any documentation on how to setup these servers to allow storage to a remote filesystem. I can get them to work on the local storage, but due to our company backup strategy I need to have these go to a remote server. I would rather do the backups directly to this storage instead of setting up a job to copy later. Has anyone successfully implemented openssh, cygwin, or copssh to drop into a remote fileshare?
