confused by various config backend

[mathfeel]

I noticed that ccsm has selection for three different config backend. Apparently, I am currently using plain text...I got that, it mean the config. are written in ini file in ~/.config/compiz/compizconfig/

Then there is also the choice of gconf backend, which I assume means setting are store in gconf xml file somewhere. Here are some questions. What are the consequences of using a different backend? When I switch, are setting resetted? or automatically transferred?

They are automatically transfered, as far as I know. The Gconf backend just gives you access to the settings for it in gconf-editor.

Your settings are not transfered if you switch between backends, The gconf stores it in gconf xml files, flat-file stores an ini file in ~/.config/compiz/compizconfig/<profilename>.ini, and the as for the kconfig, all I know about that is that, it's for KDE :D

EDIT: Forgot to mention, if you go back to your old backend your setting will be restored, i.e.
I switch from Ini to Gconf, I have default settings, I go back to Ini, i get my settings back ;)
