On Monday The Register spotted a trending post on the Google Drive forums where a user claimed that months of Drive data suddenly disappeared, and their files went back to a state from May 2023. It’s hard to imagine losing files in this mode, since at the end of the day they are still files on your hard drive. That’s all to say that, if Google lost data, and you were in File Stream mode, there’s a good chance you don’t actually have your files anymore.

This is terrifying. You should do a Google Takeout today, just to have a copy of your data before it’s too late.
