It worked like a charm for me, created one Zip file.
Note: the Database SQL file is in a folder called "sql" in the zip file.
It backs up all tables in the Joomla chosen database, not only the joomla used ones, I liked this, but others may not.
I think restoring should be easy; upload files, import SQL file.
4/5 Stars as the homepage needs work, FAQ and Documentation is minimal. If anybody has spare time, help the developer.
