Snapshot not compatible with Multi-DB plugin

Hi there,

I just tested Snapshot plugin with Multi-DB plugin(16 Databases), in a Wordpress Multisite installation.
The Snapshot plugin works well, BUT backups ONLY ONE database: the database of the main site.

So, following these old forum questions, Snapshot seems to be NOT compatible with Multi-DB.
