Hi Everyone,

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.

Can anyone provide some insight for me?

CentOS 6.5.
