Google Drive not as secure as you may think

We use Google drive to backup all our sensitive and important information. When we logged in yesterday, to our horror all the information Files and folders were gone. This information dates back approximately 1-2 years updated monthly. All gone. We interacted with Google (most probably an AI agent) resulting in the following outcome "Either the data was not up loaded or it is was deleted and too old to retrieve" after spending an hour online with them. We were under the impression that Google drive was a safe place. Don't trust it, make other arrangements if you have important data. Quite disappointed
