A willing, yet lacking backup plugin

In theory, this could be the n. 1 wp backup plugin, with plenty of features that other services offer only on payment: backup scheduling, cloud and webdav upload etc.
When put to the test, it is nevetheless hard to setup, has a cluttered interface and (even worse) sometimes just does not work. Hope the developer will keep on working at this plugin — with some improvements it could really become one of the best in its category.
