Matthias I get it but as I said I think it’s more likely for your HDD to break than for Google, Apple, Microsoft to shut down their cloud storage division without a prior notice for you to have time to download your data. I know that Google doesn’t have the best reputation when it comes to keeping services alive. killedbygoogle.com doesn’t exist for nothing 😅. But Stadia and Google Cloud Storage are 2 different things with different priorities for Google as far as I know. And even in Stadia’s case we’ve got a 3 months notice and refunds for everything bought through Google Store. Again different users have different needs and depending on how valuable that data is for you you’re better with 2-3 physical backups than using cloud storage. But I’m maintaining my opinion that for a casual user Google Cloud or other reputable provider is more reliable than your HDD/SSD.
