Backups not working

I am using Snapshot Pro for backing up my client's site. I have set up her Google Drive and successfully authorized it. Her Google Drive is also set as the destination.

My current snapshot set up is for a once weekly backup (not a very busy website) and it's not scheduled again until next Monday. Yesterday, I wanted to test the destination so I clicked on "Run Now" under the snapshot name in the snapshot listings page. Then under the Interval column there was a notice that it was creating a backup. However, it's a day later now, and it has still not yet shown up in the client's Google Drive folder. Is it also supposed to be listed in the snapshot under "All Archives" at the bottom of the page? I currently have zero archives listed there even though I have been running the backup (previously set to local destination) for a couple of weeks now.
