I'm curious if your plugin works with multi-db from wpmu?
Basically, instead of running a single database my WordPress website uses 256 databases + 1 global database + 10+ vip databases.
Is your plugin smart enough to automatically look at my setup, realize I am running multiple databases, and backup everything properly? I believe it it looks for the db.php & db-config.php files in wp-content directory, then it would instantly know that I am running multiple databases.
