G Suite Happy Ending
Every month, I drop all of my Google files into my OneDrive using "Google takeout". I don't have to use my own bandwidth, just select all of the data I want (everything), choose to have it sent into my OneDrive, then once it's done (takes a few hours) I delete older backups if I need space (with 1TB of OneDrive space, I can hold about 20 of these Google data backups). That way I ensure I always have an almost-up-to-date backup of all of my Google data that I can use to re-start all of my accounts on another provider, if needed.
