Snapshot Destinations Issue

Greetings all,
I've set up Snapshot Pro backups for a number of subsites on my Multisite install. I've created a destination on Google Drive for the archives to save to but they never seem to make it. Destination stays in pending and I never see any files show up in the Google Drive directory. It looks like the connection is verified to Google and sound but not sure if I actually have any archives there except the first test. I've programmed them to back-up once daily and save 7 days worth of archives. Any thoughts as to what might be going on? I've activated access for WPMU in the admin.

Thanks in advance for the look.
