I've used rclone[1] with great success (it can sync specific folders which looks like what you want) but I've since then moved on to a commercial service called Insync[2] because I was having rate limiting problems with the Google Cloud API key that rclone needs. I do wonder that I should move back to rclone because I don't like a third party having access to my google drive. As it goes without saying, use a good encrypted backup solution. I like cryfs for encrypting data. [1]: https://rclone.org/ https://rclone.org/ [2]: https://www.insynchq.com/ https://www.insynchq.com/ [3]: https://www.cryfs.org/ https://www.cryfs.org/
