Are templates stored in the database? Where is forumhome stored?

[doob]

This is a noob question, but I'm modifying forumhome and other templates in order to accomplish a sidebar.

I don't see .php on the server to control these so have been making changes via the Admin Control Panel and keeping track of versioning in a local directory.

Are template changes stored in the database or somewhere else? I want to make sure that I have a disaster recovery strategy as far as backup and restore and also that I'm planning for easy migration to a new server or hosting company.

1) So where for instance would I go to access FORUMHOME besides through the control panel?

2) What is the best way to backup template changes and track those changes?

3) Are templates stored in the database? Or do I need to back them up seperately.

4) Are other changes I make in the Admin CP saved to the database such as changing the webmaster's email, etc.?

Thanks for your guidance!
