here's an idea to make pwg more user friendly for new users: a backup plugin

Just a easy to use minimal front end for dumping the database on a schedule, and the ability to restore as well.
Might as well include the config files ('local/')

Even better would be the ability to upload backups to a cloud service like dropbox, google drive, or even a custom FTP server or something.

Similar plugins exist for other software like Wordpress (Updraft) and forum phpBB (Auto db backup)
