I have 2 sftp servers sitting on my dmz.  I was going to load balance/HA configure them since they are currently each a stand-alone solution.  I can use the F5 to create a vip and assign it to a dns name on the outside of my firewall... the trouble is, how do I keep both servers file systems in synch?  anyone do this before?  the pragma software doesn't appear to have this feature, or I haven't found it yet :-)   if the data drives were synchronized every few minutes I could just let the F5 handle the inbound traffic, and my Tidal app on the inside can sweep 1 server for files (also using a dns name on the inside. 

thanks in advance
