WP Snapshot (cloud) on a very large site


We use WP Snapshot Pro on much smaller sites without issues but currently using WP Migrate Pro for backups on our main site (eckerd.edu) since its an extremely large site with a ton of files (multiple GB’s)

I was wondering if this might be too much for WP Snapshot to process and a. freeze or b. worse, freeze the website? I wanting to (since its so large) have the backups sent to Google Drive.

Have there been reports of people having issues using WP Snapshot on a site that let’s say larger than 3-5GB?

Thanks so much,
