How to document a web application server ?

[Oxii]

I have a web app server and I would like to document its configuration but I'm a little bit lost and don't know where to start. I want to include:
-Environment
-OS
-Servers (apache httpd - tomcat)
-app structure
..
.. etc

Does anyone have a template or something similar to help me ?

I am a desktop user, but that is a start.

I like rsync and add a few commands to provide extra documentation.

I used this as a starting point and added my own commands.

Sample rsync file, use a text editor and paste into a file & name it mybackup.sh

This is now getting very old - 2006 but servers have not changed all that much.
Document system backup or multiple install:

Does not include a lot of other server folders you probably want to include.
