I highly recommend the "Arq" [1] commercial program for backing stuff up to these kinds of services. They support most of the big names (AWS, Google, Dropbox, etc.) and will probably be supporting the new Google options soon.
It does local encryption before sending your data up to the cloud.
Notably Arq restores all macOS permissions/meta-data, and there is an open-source test kit to show whether such a program does so.
It also works on Windows.
I have no relationship with the company, other than as a happy user.
