LCS is entirely based on XML. No database are required, which makes the setup and backup way easier. You just need to upload the files onto your server, and call http://your_server/lcs_path/admin. Enter the basic settings, and your backoffice is up and running.

There are actually 2 folders : the administrative site (/admin), which is the backoffice itself, and the "content" folder, containing all you'll enter from the backoffice. You can (should) move this folder to a non-accessible directory, in order to improve security. If you do this prior to call the /admin for the first time, you'll be prompted for the content path. Else you'll need to modify consts.inc.php yourself to change the path of your content folder.
