I, too, miss the Google backup function. I haven't kept close track of what happens when it fails (I've just backed up to my c: drive and then manually moved the backup file to my google drive via the web view) but for what it's worth --- it seems that I'm getting a new and more informative error message (below). Does this indicate that perhaps the Rootsmagic app itself needs to be verified with Google as a trusted program rather than being an individual account authorization issue? Anyway --- FYI in case it's helpful to someone. I certainly don't know what to do with it!
Context: I don't have any synced drives. I've turned off OneDrive and I do a manual backup to an external hard drive. My only mode of backing up to Google was to use the "back up --> to google drive" option. [I am planning to ditch the external backup drive & install Google Backup & Sync, though. A big thank you to all the folks who pointed out in other threads that syncing of the actual *.rmgc file risks a corruption issue. I'll be sure to exclude the Rootsmagic folder from the sync list and instead will put the backup file in a separate folder on my c:drive for sync.]
