[TriLUG] "Mirror" web servers ?

[Kevin Hunter]

If I have a RH 7.2 server running Apache, Tomcat, mySQL, can I
"mirror" my setup across the wire to a 2nd server w/ same software
installed that's setup to be my disaster recovery web server ?

How ?
Can I tunnel the "mirroring" through SSH ?

I think the only directories I'd really need to mirror would be:

/usr/local/tomcat/webapps
/usr/local/tomcat/conf
"htdoc" dir for the web site
/usr/local/mysql/data

Thx for any and all advice!!
