Hi,
Thank you for your interest!
> My question is: Why is this dividing up the site?
UpdraftPlus takes this approach, because it makes it a lot easier/quicker to restore an individual component. On most WordPress sites, once they grow, 90%+ of the data is in the media library (i.e. uploads). If you have a dodgy plugin update, and just want to restore the previous plugin, then it is inefficient/annoying to need to download the entire media library back from the remote storage location (Dropbox, etc.) just to be able to do pull out a single plugin from it. So, UpdraftPlus splits the backup into plugins/themes/uploads/others/database, for more convenient restoration.

Yes; UpdraftPlus knows to send the complete backup set to a remote site, if that is the operation you are performing.

Is this about a multisite install (i.e. WPMU)? Yes, in that case, UpdraftPlus backs up the entire install.
Best wishes,
