I need to keep 2 systems identical. Mostly e-mail directories, web directories, mysql, etc. The goal here is to have a 2nd system ready to go it the first one starts to exhibit hardware issues.
What are options to have this happen? I'm going out on a limb and thinking rsync but I haven't used it past just simple use cases.
You can try lsyncd.
https://code.google.com/p/lsyncd/
It's basically a daemon monitoring inotify events and sending them to an rsync, so it can keep things up to date more easily. (I have never used it myself, so caveat emptor.)
