Hi Chad.
What a shame the Google Drive Filestream application works this way…
Like you, I use URbackup to backup drives from Google, using the Google drive client in Windows. I too had planned to replace the old drive with the new Google File Stream application.
BTW, I make backups because of my lack of trust in cloud providers. All major cloud providers had had issues, and I know from work experience how various other service providers act.
Back on track, the only suggestion I can come up with, is to uninstall the Google File stream application, and install the Google Backup and Sync client instead. But I haven’t tested it, so I don’t know if it’s any better. Or maybe buy the Insync client (https://www.insynchq.com/downloads), who have a Linux client as well.
Of course it would be great to see URbackup use an API in the Filestream client to retrieve data, if possible.
