The best backup plugin I’ve used up to now

It does exactly what I need. It creates full or partial backups, including the feature of schedule. Schedule sometimes doesn’t work and there also some problems on big websites (more than 1GB of files) that the plugin isn’t able to create the backup at all (even manually), but most of the times I believe it’s a server problem. After all most of the times it works properly without any bug, it’s simple and nice!
