Checked if my permissions were right, chenged the names of the tables and everything but it was a complete waste of time.
It does connect to the database though, but a fresh 2.5 install is quicker and better.
And if you want to be able to have a quick recovery of your site, then this is what you are looking for.
Recovery is as simple as eating a Double Whopper Hamburger. It only takes time, but in that time you have a great taste. If you want a special Burger, with extra mayonaise on it, or clone your site to a different host, well then you need to take care of two or three details like preventing dripping on your penguin-shirt (database name and db password and stuff like that).
And with this extension, there is excellent documentation.
Could not find anything wrong with this extension but the lack of scheduled, automated backups.
