I'm already using this for many years however but it seems you missed the part in the post where data privacy and security is of utmost importance. I wouldn't want extremely crucial and private data on Google's servers. There's a reason why Swiss vaults exist to provide complete secrecy. Even the people holding your item might not know what they are holding there, not the same thing with holding private info on Google where if someone gets access to your phone for example also somehow manages to access your data... Also they don't provide the kind of data encryption you need. Example whatsapp data is encrypted but not when you're hosting it on Google drive. :)
