CodeIgniter in Subdirectories Using .htaccess

I backup projects like this:

1. copy the complete project into a sub_domain_root/whatever directory
2. copy this .htaccess into your sub_domain_root
DirectoryIndex index.php index.html

RewriteEngine on
# MAYBE adjust the following to your own paths
# RewriteCond $1 !^(index\.php|images|css|robots\.txt|favicon\.ico|Sitemap\.xml|sitemap\.xml)

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?$1 [L]

3. copy your index.php into your sub_domain_root AND adjust paths
