Configuring OS X Lion as server (without server.app) I purchased a Mac Mini Server (2x500 GB) with Snow Leopard Server. I upgraded to Lion (not Server).
The Mac Mini should act as a Homeserver for my development. My needs are:


Time Machine on HD2 for the Minis HD1 and for my MacBook (I'm sure 500GB are sufficient)
MAMP installed from macports.org
24/7 uptime
ssh from dynamic DNS
screen sharing from local network


I use Lion Server at work and figured I don't need it for the Mini at home, since I have no user management, don't want to use the built-in Apache and have read numerous discouraging reviews.

My question is, is there any advice available how to configure Lion for my purposes? It's hard to google for that, any search query containing "Lion" and "Server" will return references to Lion server - even finding tags for this page is difficult :)

For example, do I have to configure Time Machine in a certain way, or is there anything special the Server app has for time machine? 
How should I configure admin access?

I would appreciate advice or pointers to websites.

Thanks in advance!
I would do it this way


Configure Time Machine in you Mac Mini Server 
Share HD2 or create a shared folder in HD2 to save the backups from your MacBook
Configure Time Machine in your Macbook to save on a Network folder (The shared folder in your MacMini)
In your Mac Mini enable screen sharing and remote login (this last one for SSH)


Make sure your firewall in your Mac Mini is set up correctly to allow incoming connections
