This is why you don’t use any singular storage medium without backups
Ftfy. Using any medium as the exclusive location of your data without any backup is a stupid idea, but if you’re gonna be that careless, using Google Drive is one of the less stupid options out there. The chance that google fucks up in an irrecoverable way is infinitely lower than you fucking your local storage up or your house burning down.
Privacy is another factor to this of course, but if we’re just looking at the security of your data, using only Google is way better than using only your self hosted solution.
