My company is so tiny that twenty-three years' worth of records fits into less than 3.5 GB. That goes into my free Dropbox as my offsite backup. Otherwise, all the backups go on external drives and I just pray the house doesn't catch fire. I think it's probably from being on so many sites as a contractor and seeing endless problems of one kind or another with cloud stuff that I'm very old-timey in my approach to storage. Not that I think your Google Drive stuff is in danger. I just know I've had far fewer problems with my own drives than the cloud does.
