Y(standby) can ssh to X, but X cant ssh to Y. X will need a hop server
to do so. But Y can ssh/scp directly from X. So Y (standby) copies the
files from X (primary) and applies. This is what network security guys
gave me to work on. It's messy I know. One of the toughest
requirements I worked on.
Log files are switched every 10 minutes to ensure data loss of no more
than 10 minutes.
