Oh, okay, oh dear, sorry - I've missed the point and feel like a fool 
So the servers in question are local to each other, that's a good place to start. Now I think I understand better your need. Sadly, it depends .......
I think that there are three main options:-
There will be a network lag to be taken whichever you choose so none of them are 'free' so it boils down to your choice. I would suggest option 3 is probably safest but it really depends on the amount of data written. There are a few risks though:-
Does this help clarify things, or are you still unsure? Sorry, that I'm all questions.

So the servers in question are local to each other, that's a good place to start. Now I think I understand better your need. Sadly, it depends .......
I think that there are three main options:-
- Copy files on completion to FTP server
There is the cost of disk and the time taken to perform the copy. Your choice of copy tool depends on how much data is being written each time. If the files are entirely new, then rsync will not gain much (if anything) over an scp/sftp
. - Share disk from App server to FTP server
There is a delay each time the file is read because the FTP server will pull it over the network. Implementing this and using the files will be quite easy though
. - Share disk from FTP server to App server
There is a delay as the file is being written because the App server will have to write over the network. Implementing this and using the files will be quite easy though
There will be a network lag to be taken whichever you choose so none of them are 'free' so it boils down to your choice. I would suggest option 3 is probably safest but it really depends on the amount of data written. There are a few risks though:-
- You might be writing large files that are never used, so you take the pain without actually getting any benefit, so you have to be careful not to just write everything across the network.
- Ensuring you get atomic updates is important too, so write to a temporary file then rename it once complete.
Does this help clarify things, or are you still unsure? Sorry, that I'm all questions.

ftpconfig
ftpconfig(1M) System Administration Commands ftpconfig(1M) NAME
ftpconfig - set up anonymous FTP SYNOPSIS
ftpconfig [ftpdir] ftpconfig -d ftpdir DESCRIPTION
The ftpconfig script is executed by the super user to set up anonymous FTP. Anonymous FTP allows users to remotely log on to the FTP server by specifying the user name ftp or anonymous and the user's email address as password. The anonymous users are logged on to the FTP Server and given access to a restricted file area with its own file system root. See chroot(2). The FTP area has its own minimal system files. This command will copy and set up all the components needed to operate an anonymous FTP server, including creating the ftp user account, creating device nodes, copying /usr/lib files, and copying timezone data. The passwd and group files set up have been stripped down to prevent malicious users from finding login names on the server. The anonymous file area will be placed under ftpdir. If the ftp user account already exists, then the current FTP area is used, and the system files in it are updated. All other files are left untouched. This command should be run to update the anonymous FTP area's configuration whenever a system patch is installed, or the system is upgraded. OPTIONS
-d Create a new or update an existing ftpdir without creating or updating the ftp user account. Use this option when creating guest FTP user accounts. OPERANDS
The following operands are supported: ftpdir The absolute pathname of the directory under which the anonymous FTP area is set up. EXIT STATUS
The following exit values are returned: 0 Successful completion 1 Improper usage of the command 2 Command failed ATTRIBUTES
