I thought Snapshot did total database backups, but randomly

I thought Snapshot did total database backups, but randomly discovered it is not the case. This plugin needs a multisite feature. As is it's only good for single site installs. Also think that it should not be allowed to be network activated, or at least come with a warning that it will NOT backup the whole database, just a small portion.

For reference...
